Abstract: A new species of the cleptoparasitic bee genus Microsphecodes Eickwort and Stage (Halictinae: Halictini) is described and figured from a male and female collected in Jamaica. Microsphecodes xaymacensis Engel, sp. n., is distinguished from its congeners on the basis of integumental coloration and sculpturing, and form of the male pygidial plate and genitalia.
Abstract: A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in middle Eocene (Lutetian) Baltic amber. Ctenoplectrella phaeton sp. n. is distinguished from its congeners on the basis of its body proportions, integumental sculpturing, wing venation, and pubescence, and is one of the more distinctive members of the genus. A revised key to the species of Ctenoplectrella is provided.
Abstract: The purpose of this application, under Articles 23.9.3 and 81 of the Code, is to conserve the usage of the specific name Cryptotermes dudleyi Banks, 1918 for an important economic termite pest species introduced throughout much of the world by man. The senior name, Calotermes havilandi parasita Wasmann, 1910 (currently Cryptotermes parasita), is poorly known, not widely used, and applied only to a population of restricted distribution, while the junior name has been universally used in an extensive systematic, biological, and pest management literature since 1918 when it was first proposed. It is accordingly proposed that the specific name dudleyi be given precedence over parasita whenever the two are considered to be synonyms.
Abstract: A new genus and species, Yuripopovina magnifica, belonging to a new coreoid family, Yuripopovinidae (Hemiptera: Pentatomomorpha), is described and illustrated from the Lower Cretaceous amber of Lebanon. The species represents the first definitive Mesozoic record for the Coreoidea. A cladistic analysis of Coreoidea, including the new family, is undertaken.
Abstract: Euglossa williamsi sp. n. is here described from the lowland Amazonian region in Ecuador and Peru, and as part of a small species assemblage within Euglossa consisting of E. dodsoni Moure and E. obtusa Dressler. An identification key to the males of the group is provided plus detailed figures of the new species and representative illustrations for the others. A brief discussion of the taxonomic and biogeographical implications of the new species is provided. New records in Honduras and Nicaragua are provided for the related E. dodsoni.
Abstract: We describe a fossil hydrophilid beetle Anacaena paleodominica sp. nov. from the Early Miocene amber of the Dominican Republic, which is the only definitive amber inclusion of the family Hydrophilidae documented. The species belongs to the Recent Anacaena suturalis species group known from the Nearctic, Neotropical, and Australian regions. The fossil demonstrates that representatives of the species group may already have been widespread and common by the Early Miocene, and indicates a possible Miocene/post-Miocene extinction of the aquatic insect fauna on the island of Hispaniola.
Abstract: A new genus and species of aetheogrammatid lacewings is described and figured from the Jurassic of eastern Inner Mongolia, China (Daohugou; Jiulongshan Formation). Ectopogramma kalligrammoides Engel, Huang, and Lin, new genus and species, is noteworthy for the forked c-sc crossveins and presence of veinlets between the c-sc crossveins and the presence of some marginal twigging, while still retaining many putative apomorphies with the slightly more extreme venation of Aetheogramma Ren and Engel (Early Cretaceous; Yixian Formation). The wing venation provides a tantalizing link between the more extreme venation of the younger and more derived Aetheogramma speciosum Ren and Engel, nomen emendatum, and the venation of families such as Kalligrammatidae. Ectopogramma is placed in a separate subfamily, Ectopogrammatinae, new subfamily. The genus Kalligrammina Panfilov is considered as family incertae sedis.
Abstract: A new study of a surviving syntype of Trigona meadewaldoi Cockerell, 1915, was undertaken and several widely employed names for Neotropical stingless bees recognized as junior synonyms. A lectotype is designated for T. meadewaldoi and the following new synonymies established: Tetragona francoi Moure, 1946, and Trigona (Frieseomelitta) freiremaiai Moure, 1963. These nomenclatural matters are here settled and the species thoroughly characterized in advance of a forthcoming phylogenetic consideration of the genus Frieseomelitta von Ihering, 1912.
Abstract: The application of non-invasive imaging technologies using X-radiation (diagnostic radioentomology, âDRâ) is demonstrated for the study of amber-entombed social bees. Here we examine the external and internal morphology of an Early Miocene (Burdigalian) stingless bee (Apinae: Meliponini) from the Dominican Republic using non-destructive, X-ray microtomography analysis. The study permits the accurate reconstruction of features otherwise obscured or impossible to visualize without destroying the sample, and allows diagnosis of the specimen as a new species, Proplebeia adbita Greco and Engel.
Abstract: Agulla protomaculata, new species (Raphidiidae: Raphidiinae), is described and figured from a series of males and females preserved as fine compressions in middle Eocene shale from the Green River Formation of Colorado. The specimens are exquisitely preserved, complete with integumental color patterns. The species is compared with other Tertiary snakeflies.
Abstract: A new species of the orchid bee subgenus Dasystilbe Dressler (Euglossini: Euglossa Latreille) is described and figured from a series of males and females collected broadly in Mesoamerica. Euglossa (Dasystilbe) obrima, sp. n., is differentiated from the one known species of Dasystilbe, E. (D.) villosa Moure, which occurs only in Panamá and perhaps Costa Rica. The subgenus and its constituent species are diagnosed, and comments provided on Dasystilbe.
Abstract: A second species of the enigmatic lampyrid genus Oculogryphus is described and figured as Oculogryphus bicolor sp. n. from Vietnam. The definition of the genus is slightly modified with consideration of newly detected morphological variation from this species. According to a comprehensive phylogenetic analysis including nearly 80% of documented lampyrid genera, Oculogryphus is the putative sister group to Stenocladius s. str. within the paraphyletic group of Ototretinae-Ototretadrilinae. The classification of Stenocladius is briefly discussed in this context.
Abstract: A diverse fauna of wasps of the extinct parasitoid family Stigmaphronidae (Ceraphronoidea) are recorded in Early Cretaceous (Lower Albian) amber from Spain. Seven new species in five genera are described and figured based on 51 specimens, representing more material than in all the world's other amber deposits combined. New species include: Elasmophron mari sp. nov., Libanophron sugaar sp. nov., Hippocoon basajauni sp. nov., Burmaphron jentilak sp. nov., B. sorginak sp. nov., B. iratxoak sp. nov., and Tagsmiphron olentzero sp. nov. The significance of the fauna is discussed and compared with that of other Cretaceous amber deposits, in particular the tremendous richness of the Spanish fauna is contrasted with the complete absence of stigmaphronids in the slightly younger and nearby French amber. Whether this stark difference represents particularly favorable conditions for these parasitoids, or their hosts, in the Cretaceous Spanish archipelago, or whether it is owing to taphonomic factors is discussed.
Abstract: Three new species within the stigmaphronid genus Tagsmiphron Engel and Grimaldi, 2009, and one new species within the megaspilid genus Conostigmus Dahlbom, 1858 are described from Upper Cretaceous (Campanian) amber originating at the Grassy Lake locality in Alberta, Canada. New taxa include Tagsmiphron spiculum sp. nov., T. leucki sp. nov., T. exitorum sp. nov., and Conostigmus cavannus sp. nov. The new Conostigmus species is a rare discovery. It is the third megaspilid species to be found in Cretaceous amber, with the two specimens described herein effectively doubling the number of known Mesozoic exemplars for the family. We provide the first comprehensive report of known Ceraphronoidea within Canadian amber, and contrast this against other Cretaceous amber assemblages, discussing the potential palaeobiogeographic and palaeoenvironmental implications of the Canadian amber assemblage.
Abstract: The dryinid wasp fauna of Caxiuanã National Forest, Pará, Brazil is summarized. Seventeen species, three of which are new, in six genera and three subfamilies have been found: Anteoninae: Anteon panamense Olmi, A. chiriquense (Cameron), A. noyesi Olmi, Deinodryinus bicolor (Olmi et Currado), D. bilobus Fenton, D. caxiuana sp. nov.; Dryininae: Dryinus argentinus Olmi, D. striatus (Fenton), D. snellingi Olmi, D. ruficeps Cameron, D. multicarinatus sp. nov., D. hamulus sp. nov.; Gonatopodinae: Gonatopus campbelli Olmi, G. neotropicus (Olmi), G. testaceus Cameron, Neodryinus incaicus Olmi, and Trichogonatopus neotropicus Olmi. Gonatopus neotropicus and N. incaicus are newly recorded from Brazil. The new species are described and illustrated. Keys to genera and species are provided.
Abstract: A new subgenus, Alocanthedon Engel and Gonzalez subgen. n., is described for five species of unusual Southeast Asian bees in the genus Chalicodoma Lepeletier de Saint Fargeau (Megachilinae: Megachilini). The subgenus is most noteworthy for the deep postgenal depression or furrow in males (bordered outwardly near the base of the mandible by a protuberant, thick lamella) and the presence of a dense patch of black setae posteriorly in the forewing medial cell (except in one species) [resembling the dense patch of setae among the submarginal cells of Thrinchostoma Saussure (Halictidae: Halictinae: Halictini)]. The subgenus is characterized and distinguished from the related Callomegachile Michener. A key to the following five species presently included in the subgenus is provided: Chalicodoma aterrimum (Smith), C. atratiforme (Meade-Waldo) comb. n., C. memecylonae Engel sp. n., C. odontophorum Engel sp. n., and
C. apoicola Engel sp. n. Chalicodoma (Callomegachile) atratiforme sininsulae (Cockerell) is newly placed in synonymy with C. (C.) fulvipenne (Smith). Species have been collected from Memecylaceae (Myrtales) and Fabaceae (Fabales). The phylogenetic relationships of Alocanthedon among other Megachilini are briefly elaborated upon.
Abstract: Three new genera and species of primitive termites (Isoptera) are described and fi gured from Early Cretaceous French and Lebanese ambers: Santonitermes chloeae ENGEL, NEL & PERRICHOT, n. gen., n. sp., from an imago preserved in Charentese amber (AlbianâCenomanian); Syagriotermes salomeae ENGEL, NEL & PERRICHOT, n. gen., n. sp., from an alate detected in opaque amber from the same locality and reconstructed using synchrotron microtomographic imaging; and Lebanotermes veltzae ENGEL, AZAR & NEL, n. gen., n. sp., from an alate preserved in Lebanese amber (Aptian). The three genera exhibit primitive features of the Meiatermes-grade of early isopteran genera (sensu ENGEL et al. 2009). In addition, three further fragmentary specimens from Lebanon amber are reported, each
apparently distinct from Lebanotermes n. gen. and the previously described Melqartitermes ENGEL et al., 2007. The new fossils further document the diversity and morphological disparity of âlowerâ termite groups during the Early Cretaceous, highlighting the importance of palaeontological material for understanding isopteran phylogeny as well as the diversifi cation of Isoptera in the latest Jurassic and Early Cretaceous.
Abstract: Two new species of Chalicodoma Lepeletier de Saint Fargeau subgenus Alocanthedon Engel & Gonzalez are described and figured from Indonesia and Malaysia. Chalicodoma (Alocanthedon) indonesicum Engel & Schwarz, nov.sp., is described from two males collected on Siberut Island (Mentawai Island Chain) and Central Java (Indonesia). From Sarawak (Malaysian Borneo) is described C. (A.) trusanicum Engel, nov.sp., also only known from the male. Both species are superficially similar to C. (A.) memecylonae Engel 2011 from Peninsular Malaysia.
Abstract: A new subgenus of Protandrena Cockerell (Panurginae: Protandrenini) from South America, Andinopanurgus Gonzalez & Engel, subgen. n., is described and figured for distinctive species of the genus occurring at mid- and high elevations in the Andes from Venezuela to Peru (1100-3400 m). In addition to the distribution, the subgenus is easily distinguished from other subgenera by a unique combination of morphological characters in both sexes, especially in the hidden sterna and genitalia of the male. Protandrena amyae sp. n., and P. femoralis sp. n., are also described and figured from the Ecuadorian and Peruvian Andes. New geographical records and a key to the species are also provided.
Abstract: Two new earwigs (Dermaptera) recently discovered in mid-Cretaceous (latest Albian) amber from Myanmar are described and figured. Astreptolabis ethirosomatia gen. et sp. n. is represented by a peculiar pygidicranoid female, assigned to a new subfamily, Astreptolabidinae subfam. n., and differs from other protodermapterans in the structure of the head, pronotum, tegmina, and cercal forceps. Tytthodiplatys mecynocercus gen. et sp. n. is a distinctive form of first-instar nymph of the Diplatyidae, the earliest record for this basal earwig family. The taxon can be distinguished from other Early Cretaceous nymphs by the structure of the head, antennae, legs, and most notably its filamentous and annulate cerci. The character
affinities of these taxa among Neodermaptera are generally discussed as is the identity of an enigmatic âearwig-likeâ species from the Jurassic of China.
Abstract: New material of the wasp family Maimetshidae (Apocrita) is presented from four Cretaceous amber deposits â the Neocomian of Lebanon, the Early Albian of Spain, the latest Albian/earliest Cenomanian of France, and the Campanian of Canada. The new record from Canadian Cretaceous amber extends the temporal and paleogeographical range of the family. New material from France is assignable to Guyotemaimetsha enigmatica Perrichot et al. including the first females for the species, while a series of males and females from Spain are described and figured as Iberomaimetsha Ortega-Blanco, Perrichot & Engel, gen. n., with the two new species Iberomaimetsha rasnitsyni Ortega-Blanco, Perrichot & Engel, sp. n. and I. nihtmara Ortega-Blanco, Delclòs & Engel, sp. n.; a single female from Lebanon is described and figured as Ahiromaimetsha najlae Perrichot, Azar, Nel & Engel, gen. et sp. n., and a single male from Canada is described and figured as Ahstemiam cellula McKellar & Engel, gen. et sp. n. The taxa are compared with other maimetshids, a key to genera and species is given, and brief comments made on the family.
Abstract: A new genus and species of microphysid bug is described and illustrated from two individuals preserved in Late Cretaceous (Campanian) amber from Alberta, Canada. Popovophysa entzmingeri gen. et sp. nov. is distinguished from its fossil and modern counterparts. The new species has attributes of the two currently recognized subfamilies Ciorullinae and Microphysinae, suggesting that those taxa may not be distinct and are in need of cladistic analysis.
Abstract: Rhadinolabis phoenicica Engel, Ortega-Blanco & Azar gen. et sp.n. is described and figured from two female earwigs preserved in Early Cretaceous amber from Lebanon, representing the oldest Dermaptera in amber. In addition a partial nymph is recorded from the same deposits. The placement of the genus among Neodermaptera is briefly discussed.
Abstract: The female of Pyrocoelia prolongata Jeng and Lai, a diurnal lampyrid species from Taiwan, is described for the first time. A single individual was found in a small, shady, dry streambed at the edge of a mixed forest at 2700 m elevation. The individual glowed in darkness and would move its abdomen up and down when disturbed and as a deterring behavior. A key to the females of the species of Pyrocoelia Gorham in Taiwan is provided. The morphology of photogenic organs of females and the function of bioluminescence of day-active species of Pyrocoelia are discussed.
Abstract: Species of the extinct, parasitoid wasp family Serphitidae (Proctotrupomorpha: Bipetiolarida: Serphitoidea), occurring in Cretaceous (Turonian) amber from New Jersey, are reviewed. Two species, both new, are described and figured as Serphites raritanensis Engel & Grimaldi sp.n. and S. navesinkae Engel & Grimaldi sp.n.
Abstract: Apis mellifera jemenitica Ruttner (= yemenitica auctorum: vide Engel 1999) has been used in apiculture throughout the Arabian Peninsula since at least 2000 BC. Existing literature demonstrates that these populations are well adapted for the harsh extremes of the region. Populations of A. m. jemenitica native to Saudi Arabia are far more heat tolerant than the standard races often imported from Europe. Central Saudi Arabia has the highest summer temperatures for the Arabian Peninsula, and it is in this region where only A. m. jemenitica survives, while other subspecies fail to persist. The indigenous race of Saudi Arabia differs from other subspecies in the region in some morphological, biological, and behavioral characteristics. Further taxonomic investigation, as well as molecular studies, is needed in order to confirm whether the Saudi indigenous bee populations represent a race distinct from A. m. jemenitica, or merely an ecotype of this subspecies.
Abstract: New Upper Carboniferous (Pennsylvanian, Westphalian A) insects are described from localities in the Pottsville Formation of northern Alabama (including the Union Chapel Mine). Five species are recorded in five palaeopterous orders and comprising five genera (four new to Science). New taxa proposed are: Anniedarwinia alabamensis Beckemeyer and Engel new genus and species (Ephemeropterida: Syntonopterodea: Syntonopteridae); Pharciphyzelus lacefieldi Beckemeyer and Engel new genus and species (Palaeodictyopterida: Palaeodictyoptera: Homoiopteridae), Camptodiapha atkinsoni Beckemeyer and Engel new genus and species (Palaeodictyopterida: Diaphanopterodea: Namurodiaphidae); Agaeoleptoptera uniotempla Beckemeyer and Engel new genus and species (Palaeodictyopterida: Megasecoptera: Ancopteridae); and Oligotypus tuscaloosae Beckemeyer and Engel, new species (Odonatoptera: Protodonata: Paralogidae). Each taxon is described, figured, and compared with close relatives in Carboniferous and Permian deposits. Camptodiapha new genus extends the geographical range of the family Namurodiaphidae into the Carboniferous of North America. The diagnosis of the family Ancopteridae is expanded to accommodate Agaeoleptoptera new genus rather than propose another monogeneric family. The distribution of Ancopteridae is extended geographically into North America and temporally into the Upper Carboniferous. A key to the genera of ancopterids is provided.
Abstract: Forty-eight family-group names are identified for insects among the Isoptera (termites), representing a nearly 19% increase since the last compilation less than 10 years ago. Accordingly, these names are newly catalogued, including various updates from the original summary. The name Reticulitermitidae is recognized as a nomen nudum while Caatingatermitinae is newly considered a nomen invalidum, and neither is available in zoological nomenclature. A catalogue of the suprafamilial names for Isoptera is appended. The
name Xylophagodea is formally proposed for the Isoptera + Cryptocercidae clade.
Abstract: The family Scelembiidae (Neoembiodea: Embiomorpha: Archembioidea) is recorded from Asia for the first time, based on two individuals preserved in Early Eocene amber from the Cambay Basin, western India. Kumarembia hurleyi Engel & Grimaldi, gen. n. et sp. n., is described, figured, and distinguished from other archembioid genera. The genus shares male genitalic features with scelembiids, otherwise known from South America and Africa.
Abstract: The Miocene Randeck Maar (southwestern Germany) is one of the only sites with abundant material of fossil honey bees. The fauna has been the focus of much scrutiny by early authors who recognized multiple species or subspecies within the fauna. The history of work on the Randeck Maar is briefly reviewed and these fossils placed into context with other Tertiary and living species of the genus Apis Linnaeus (Apinae: Apini). Previously unrecorded specimens from Randeck Maar were compared with earlier series in an attempt to evaluate the observed variation. A morphometric analysis of forewing venation angles across representative Recent and Tertiary species of Apis as well as various non-Apini controls was undertaken to evaluate the distribution of variation in fossil honey bees. The resulting dendrogram shows considerable variation concerning the wing venation of Miocene Apini, but intergradation of other morphological characters reveals no clear pattern of separate species. This suggests that a single, highly variable species was present in Europe during the Miocene. The pattern also supports the notion that the multiple species and subspecies proposed by earlier authors for the Randeck Maar honey bee fauna are not valid, and all are accordingly recognized as Apis armbrusteri Zeuner.
Abstract: The fauna of termites (Isoptera) preserved in Early Eocene amber from the Cambay Basin (Gujarat, India) are described and figured. Three new genera and four new species are recognized, all of them Neoisoptera â Parastylotermes krishnai Engel & Grimaldi, sp. n. (Stylotermitidae); Prostylotermes kamboja Engel & Grimaldi, gen. et sp. n. (Stylotermitidae?); Zophotermes Engel, gen. n., with Zophotermes ashoki Engel & Singh, sp. n. (Rhinotermitidae: Prorhinotermitinae); and Nanotermes isaacae Engel & Grimaldi, gen. et sp. n. (Termitidae: Termitinae?). Together these species represent the earliest Tertiary records of the Neoisoptera
and the oldest definitive record of Termitidae, a family that comprises >75% of the living species of Isoptera. Interestingly, the affinities of the Cambay amber termites are with largely Laurasian lineages, in this regard paralleling relationships seen between the fauna of bees and some flies. Diversity of Neoisoptera in Indian amber may reflect origin of the amber deposit in Dipterocarpaceae forests formed at or near the paleoequator.
Abstract: The first fossil of the staphylinine tribe Diochini Casey is described and figured from an inclusion in mid-Eocene (Lutetian) Baltic amber. Diochus electrus sp. n. is distinguished from its congeners and the diversity of rove beetles (Staphylinidae s.l.) is summarized briefly.
Abstract: Euglossella, one of the most distinctive subgenera of orchid bees of the genus Euglossa, is composed of two characteristic assemblages of species, one of them comprising bees bearing the strongly metallic integument trademark of the genus (viridis species group), and the other consisting of bees with a brown integument shaded with metallic iridescence (decorata species group). Here we provide the first of two parts of a revision of Euglossella, providing diagnostic definitions for the subgenus, the decorata species group, and all the species included therein. Six species are included in the decorata group, one new: Euglossa (Euglossella) aurantia, sp. n.; E. (E.) apiformis Schrottky, resurrected status; E. (E.) decorata Smith, revised status; E. (E.) singularis Mocsáry, revised status; E. (E.) cosmodora Hinojosa-DÃaz and Engel; and E. (E.) perpulchra Moure and Schlindwein. Euglossa meliponoides Ducke and E. urarina Hinojosa-DÃaz and Engel are newly synonymized under E. decorata, E. decorata ruficauda Cockerell is synonymized under E. singularis, and a neotype is designated for E. apiformis.
Abstract: The bee genus Chilicola Spinola (Xeromelissinae) is recorded from the State of Bahia, Brazil for the first time, based on a new species of the megalostigma group of the subgenus Hylaeosoma Ashmead. Chilicola (Hylaeosoma) kevani sp. n. is described and figured from males collected in Wesceslau Guimarães, Bahia. The species can be distinguished on the basis of coloration, size, integumental sculpturing, and structure of the hidden metasomal sterna and genitalia. A revised key to the species of the megalostigma group is provided.
Abstract: Megalopta (Noctoraptor) notiocleptis Engel, new species (Halictinae: Augochlorini), is described and figured from a female captured in central Bolivia, representing the first record of this parasitic lineage for the country. The species is distinguished from other cleptoparasitic Megalopta and its putative host documented from the same locality as M. (Megalopta) nitidicollis Friese.
Abstract: A new genus and species of earwig is described and figured from Early Cretaceous (Latest Albian-Earliest Cenomanian) amber of southwestern France. The holotype was studied using traditional light microscopy as well as through propagation phase contrast X-ray synchrotron microtomography, rendering high resolution three dimensional models for critical examination. Gallinympha walleri Perrichot & Engel, new genus and species, is represented by two late instar nymphs missing only portions of the abdomen, as well as most of the head for the paratype. The genus is a member of the Pygidicranidae, one of the most basal of living earwigs, and is distinguished from other taxa in the family. A thorough account of the specimen's morphology is provided along with a detailed comparison with similar structures across a diversity of primitive earwig lineages.
Abstract: Ten amber inclusions of male Ripidiinae (Coleoptera: Ripiphoridae) are reported from Early Miocene deposits of the Dominican Republic and compared with extant species of Neorrhipidius Viana, 1958 from Argentina and Paraguay and Quasipirhidius Zaragoza Caballero, 1991 from Mexico. Neorrhipidius seicherti sp. n. and Quasipirhidius luzziae sp. n. are described and illustrated. Both species are characterised by 11-segmented antennae with eight distal antennomeres uniflabellate, mouthparts reduced to maxillary palpi represented by long styli with fused basal palpomeres, by metathoracic wings without crossveins and tarsal formula of 5-5-4. Neorrhipidius seicherti sp. n. differs from Quasipirhidius luzziae sp. n. by the presence of postocular ommatidia and by the shape of metascutellum. The distribution of fossil and extant Ripidiinae in Central America is briefly discussed. Furthermore, the frequent occurrence of Quasipirhidius luzziae sp. n. in amber as syninclusions suggests possibly unique synchronisation of emergence unknown in extant taxa or more likely intraspecific aggregative behaviour by males prior to mating with receptive females.
Abstract: A new species of Lasioglossum Curtis subgenus Dialictus Robertson (Halictinae, Halictini) is described and figured from a series of female and males collected on Sombrero Island, Anguilla; the northernmost island of the Lesser Antilles. Lasioglossum (Dialictus) sombrerense sp. n. is distinguished from its congeners and the name made available for a forthcoming work on the arthropod diversity of Sombrero Island.
Abstract: Five new species and one new genus of Serphitidae microhymenoptera are described from Upper Cretaceous (Campanian) amber originating at the Grassy Lake locality in Alberta, Canada. New taxa include Serphites hynemani sp.n., Serphites bruesi sp.n., Serphites kuzminae sp.n., Serphites pygmaeus sp.n. and Jubaserphites ethani gen. et sp.n. Topotype material for the type species of Serphites, Serphites paradoxus Brues is re-illustrated and redescribed in greater detail, clarifying the characteristics of the species for comparison with the numerous serphitids that have been described subsequent to the work of Brues. We provide the first comprehensive report of known serphitid specimens in Canadian amber, draw comparisons with taxa in other Cretaceous deposits, and comment upon the palaeoecological connotations of the relatively diverse and morphologically disparate Canadian serphitid assemblage.
Abstract: The fauna of false fairy wasps (Proctotrupomorpha: Bipetiolarida: Mymarommatoidea) occurring in Early Cretaceous (Albian) amber from north and northeastern Spain (Moraza, San Just, and El Soplao outcrops) is described. In total twelve specimens have been recovered and four species recognized, all new: Alavaromma orchamum, new genus and species (Alavarommatidae, new family), Archaeromma hispanicum, new species (Mymarommatidae), Galloromma alavaensis, new species, and G. turolensis, new species (Gallorommatidae). The study is indicating the necessity of revision, and maybe fusion, of both superfamilies, as the boundaries between them are less and less defined. However, major classificatory rearrangements must await the completion of the cladistic studies presently underway.

Abstract: Despite centuries of research addressing amber and its various inclusions, relatively little is known about the specific events having stimulated the production of geologically relevant volumes of plant resin, ultimately yielding amber deposits. Although numerous hypotheses have invoked the role of insects, to date these have proven difficult to test. Here, we use the current mountain pine beetle outbreak in western Canada as an analogy for the effects of infestation on the stable isotopic composition of carbon in resins. We show that infestation results in a rapid (approx. 1 year) 13C enrichment of fresh lodgepole pine resins, in a pattern directly comparable with that observed in resins collected from uninfested trees subjected to water stress. Furthermore, resin isotopic values are shown to track both the progression of infestation and instances of recovery. These findings can be extended to fossil resins, including Miocene amber from the Dominican Republic and Late Cretaceous New Jersey amber, revealing similar carbon-isotopic patterns between visually clean ambers and those associated with the attack of wood-boring insects. Plant exudate δ13C values constitute a sensitive monitor of ecological stress in both modern and ancient forest ecosystems, and provide considerable insight concerning the genesis of amber in the geological record.
Abstract: The diversity of serphitid wasps (Proctotrupomorpha: Serphitoidea) in Early Cretaceous (Albian) amber from Spain is described. Four new species have been found representing the genera Serphites Brues 1937, Aposerphites Kozlov and Rasnitsyn 1979, and Microserphites Kozlov and Rasnitsyn 1979. From the Peñacerrada I (Moraza) outcrop two species are described as Aposerphites angustus Ortega-Blanco, Delclòs, Peñalver and Engel, new species and Serphites lamiak, new species. A single species was found at the San Just (Teruel) outcrop and is described as S. silban, new species. Another single specimen was found in El Soplao (Cantabria) outcrop, described as Microserphites soplaensis, new species. This last specimen is especially interesting in sharing typical serphitid and mymarommatoid characters, giving additional support to the apparent close relationship of both groups.
Abstract: The purpose of this application, under Article 75.5 of the Code, is to conserve the name Apis armbrusteri Zeuner, 1931 for a species of fossil honey bee occurring in the Miocene fauna of southwestern Germany. The holotype is the hollow impression of a bee from the Early Miocene Böttingen Marmor and, aside from attributing the taxon to the tribe APINI, no details regarding its specific identity can be gleaned from this specimen. Nonetheless, this name has been universally applied to the Early Miocene honey bees from Böttingen Marmor and the related contemporaneous site from the same crater series, Randeck Maar, since Zeuner & Manning (1976). Although A. armbrusteri is recognised as a nomen dubium, to resurrect the unused specific epithet Apis scheuthlei (Armbruster, 1938) for these bees would be counter to current usage and would destabilise a voluminous literature on honey bee evolution and ecology. It would also threaten the subgeneric name Cascapis Engel, 1999 as A. armbrusteri sensu Zeuner & Manning (1976), i.e. based on the Randeck Maar material, is its type species by original designation. Accordingly, it is proposed that the unidentifiable holotype be set aside and one of the more exquisitely preserved and easily diagnosable specimens from this same fauna be designated as neotype, thereby stabilising the honey bee taxonomy and bringing the application of the name A. armbrusteri in line with universal current usage.
Abstract: The braconid wasp subfamily Protorhyssalinae is recognized from Early Cretaceous (Albian) amber of Peñacerrada, Spain. Protorhyssalopsis perrichoti Ortega-Blanco, Delclòs, and Engel, new genus and species, is described and figured from a single female and differs from the other two genera ascribed to this doubtfully natural subfamily. The new genus differs in details of wing venation, and mesosomal and mouthpart morphology from Protorhyssalus Basibuyuk et al. (in Turonian New Jersey amber) and Protorhyssalodes Perrichot et al. (in Albian-Cenomanian French amber). The uncertain subfamilial placement for the recently described genus Aenigmabracon Perrichot et al. is also briefly discussed.
Abstract: The chrysidoid wasp family Embolemidae (Chrysidoidea: Dryiniformes) is recorded in Early Cretaceous (Albian) amber from Peñacerrada (Spain). Embolemus periallus Ortega-Blanco, Delclòs, and Engel, new species, is the first definitive embolemid in Cretaceous amber and the first definitive record of the family from the Mesozoic. The new taxon is described, illustrated, and compared with its modern counterparts. The geological history of the family is reviewed and the putative placement of the Early Cretaceous genus Baissobius briefly discussed.
Abstract: A remarkable bilaterally asymmetrical gynandromorph of the augochlorine bee Thectochlora alaris (VACHAL 1904) (Halictinae: Augochlorini) is described and figured. This is only the second documented gynandromorph for the bee tribe Augochlorini and one of the most dramatic in its complete asymmetry. Despite the deformity of the usual acarinarium present in species of Thectochlora, the individual was found in association with at least six deutonymphs which are likely of Thectochloracarus neotropicalis FAIN, ENGEL, FLECHTMANN & OCONNOR 1999. -----Zusammenfassung: Eine bemerkenswerte bilateral asymmetrische Gynandromorphie der augochlorinen Biene Thectochlora alaris (VACHAL 1904) (Halictinae: Augochlorini) wird beschrieben und abgebildet. Es ist erst die zweite bekannte Gynandromorphie für die Tribus Augochlorini welche besonders augenscheinlich ist durch die vollständige Asymmetrie. Nichtsdestotrotz bestand bei diesem Tier eine für die Gattung typische Assoziation mit Milben von Thectochloracarus neotropicalis FAIN, ENGEL, FLECHTMANN & OCONNOR 1999.
Abstract: Knowledge of the Yemeni apoid fauna remains relatively scant. Here new records are provided for the allodapine bee genus Compsomelissa in Yemen. The species Compsomelissa boerneri ALFKEN is newly recorded from Yemen, and the Arabian Peninsula.-----Zusammenfassung: Die Kenntnis der Bienenfauns des Yemen ist bisher sehr spärlich bekannt. Hier können wir neue Funddaten der Bienengattung Compsomelissa für den Yemen mitteilen. Die Art Compsomelissa boerneri ALFKEN ist neuerlich aus dem Yemen und Arabien bekannt geworden.
Abstract: The male of Megachile (Eutricharaea) ventrisi ENGEL 2008 (Megachilinae: Megachilini) is described and figured for the first time and new records are provided for this interesting Arabian leaf-cutter bee. The species is newly recorded from Yemen and Oman.-----Zusammenfassung: Das Männchen von Megachile (Eutricharaea) ventrisi ENGEL 2008 (Megachilinae: Megachilini) wird erstmalig beschrieben und abgebildet, neue Nachweise dieser arabischen Blattschneiderbiene werden vorgestellt. Die Art wird konnte neu für Jemen und Oman nachgewiesen werden.
Abstract: Insects were the first animals to evolve powered flight and did so perhaps 90 million years before the first flight among vertebrates. However, the earliest fossil record of flying insect lineages (Pterygota) is poor, with scant indirect evidence from the Devonian and a nearly complete dearth of material from the Early Carboniferous. By the Late Carboniferous a diversity of flying lineages is known, mostly from isolated wings but without true insights into the paleoethology of these taxa. Here, we report evidence of a full-body impression of a flying insect from the Late Carboniferous Wamsutta Formation of Massachusetts, representing the oldest trace fossil of Pterygota. Through ethological and morphological analysis, the trace fossil provides evidence that its maker was a flying insect and probably was representative of a stem-group lineage of mayflies. The nature of this current full-body impression somewhat blurs distinctions between the systematics of traces and trace makers, thus adding to the debate surrounding ichnotaxonomy for traces with well-associated trace makers.
Abstract: A new species of leaf-cutter bee, Megachile (Eutricharaea) arachosiana, new species, is described and illustrated based on males and females from west-central and northern Pakistan. The opportunity is taken to provide new taxonomic notes on the subgenus Eutricharaea Thomson. The subgenus Platysta Pasteels, comprising the large African species M. platystoma Pasteels and M. khamana Cockerell, is synonymized with Eutricharaea (new synonymy). It is noted that M. microxanthops Cockerell, considered widely a synonym of M. concinna Smith, is allied to M. apostolica Cockerell and is removed from synonymy accordingly. A new taxonomic summary is provided for M. concinna with M. microxantha Cockerell, M. atratula Rebmann, and M. privigna Rebmann considered new junior subjective synonyms (new synonymies).
Abstract: A new species of Chlerogas Vachal (Halictinae: Augochlorini) is described and figured from Bolivia, correcting a past mis-association of sexes for Chlerogas boliviensis Brooks and Engel. Chlerogas aterrimus sp. n. is described from two males and a single female collected in the Department of Santa Cruz (Provinces of Florida and Caballero) and is distinguished from C. boliviensis, known only from females, and its other congeners. A revised key to the species of Chlerogas is provided along with a new locality record for C. boliviensis.
Abstract: The South American species of the rare bee genus Chlerogella Michener (Halictinae: Augochlorini) are revised, completing the study of the genus. Chlerogella diversity is significantly expanded beyond the five previously described South American species of Cherlogella azurea (Enderlein) comb. n., C. nasus (Enderlein), C. mourella Engel, C. octogesima (Brooks and Engel) comb. n., and C. buyssoni (Vachal). Twenty-two new species are described â C. agaylei sp. n., C. arhyncha sp. n., C. borysthenis sp. n., C. breviceps sp. n., C. cochabambensis sp. n., C. cooperella sp. n., C. cyranoi sp. n., C. dolichorhina sp. n., C. elysia sp. n., C. eumorpha sp. n., C. euprepia sp. n., C. hauseri sp. n., C. hypermeces sp. n., C. materdonnae sp. n., C. oresbios sp. n., C. picketti sp. n., C. rostrata sp. n., C. silvula sp. n., C. terpsichore sp. n., C. tychoi sp. n., C. vachali sp. n. C. xuthopleura sp. n. â and the distribution of the genus is expanded beyond Perú and Ecuador to include Bolivia, Colombia, and Venezuela. The female of C. azurea is described for the first time while the placement of Halictus buyssoni Vachal in Chlerogella is considered tentative, following the usage of previous authors, as the holotype and sole specimen is untraceable. The genus is newly diagnosed based on a greater understanding of variation in malar length across the species and a dichotomous key is provided. New floral records for species of Chlerogella include Psychotria pongoana Standl. (Rubiaceae) and a putative record on Phragmopedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae).
Abstract: A new species of Caenaugochlora Michener, subgenus Ctenaugochlora Eickwort, is described and figured from a single female from central Costa Rica. Caenaugochlora (Ctenaugochlora) perviridis, new species, is distinguished from its congeners and a new key to the species of the subgenus is provided. New locality data are recorded for two other Ctenaugochlora, C. algeri Engel and C. perpectinata (Michener), both recorded from Costa Rica and the latter from BolÃvia. Males of C. perpectinata were captured at flowers of Clethra lanata M. Martens & Galeotti (Ericales: Clethraceae). Comments on color variation in C. algeri and other augochlorines are provided.
Abstract: Among insects, eusocial behavior occurs in termites, ants, some bees and wasps. Isoptera and Hymenoptera convergently share social behavior, and for both taxa its evolution remains poorly understood. While dating analyses provide researchers with the opportunity to date the origin of eusociality, fossil calibration methodology may mislead subsequent ecological interpretations. Using a comprehensive termite dataset, we explored the effect of fossil placement and calibration methodology. A combined molecular and morphological dataset for 42 extant termite lineages was used, and a second dataset including these 42 taxa, plus an additional 39 fossil lineages for which we had only morphological data. MrBayes doublet-model analyses recovered similar topologies, with one minor exception (Stolotermitidae is sister to the Hodotermitidae, s.s., in the 42-taxon analysis but is in a polytomy with Hodotermitidae and (Kalotermitidae + Neoisoptera) in the 81-taxon analysis). Analyses using the r8s program on these topologies were run with either minimum/maximum constraints (analysis a = 42-taxon and analysis c = 81-taxon analyses) or with the fossil taxon ages fixed (ages fixed to be the geological age of the deposit from which they came, analysis b = 81-taxon analysis). Confidence intervals were determined for the resulting ultrametric trees, and for most major clades there was significant overlap between dates recovered for analyses A and C (with exceptions, such as the nodes Neoisoptera, and Euisoptera). With the exception of isopteran and eusiopteran node ages, however, none of the major clade ages overlapped when analysis B is compared with either analysis A or C. Future studies on Dictyoptera should note that the age of Kalotermitidae was underestimated in absence of kalotermitid fossils with fixed ages.
Abstract: Two new species of Caenaugochlora Michener are described and figured from Ecuador. Caenaugochlora quichua sp. n. and C. bennetti sp. n. are both remarkable for the presence of carinate preoccipital carinae, setose compound eyes, strongly rimmed metabasitibial plate, normally pectinate inner metatibial spur, metapostnotal striae not reaching the apical margin, and the male fourth metasomal sterna with lateral projections. The combination of these features intermingle attributes of the presently recognized subgenera, while others are unique to the genus as a whole. A revised diagnosis is provided for the genus and its two subgenera, with Caenaugochlora s.str. accommodating C. bennetti and C. quichua, and brief comments made regarding the implications of the characters exhibited by the aforementioned species.
Abstract: A new genus and species of sphaeropsocid bark louse is described and figured from a single individual in Early Cretaceous amber from Hammana, central Lebanon. Asphaeropsocites neli g. et sp. n. is the second sphaeropsocid described from Lebanese amber. Like Sphaeropsocites lebanensis Grimaldi & Engel 2006, it has a basal phylogenetic position within Sphaeropsocidae, and adds evidence that these insects were once widespread and global in the past. The new species is distinguished from related taxa, and a discussion and checklist of sphaeropsocids are provided.
Abstract: Three genera and species of Scydmaeninae (Staphylinidae) are described as new from mid-Cretaceous Burmese amber: Ektatotricha paradoxa Chatzimanolis, Engel & Newton gen. et sp. nov. and Electroatopos castaneus Chatzimanolis, Engel & Newton gen. et sp. nov. in the emended supertribe Hapsomelitae, and Kachinus antennatus Chatzimanolis, Engel & Newton gen. et sp. nov. in the supertribe Scydmaenitae. The supertribe Hapsomelitae is newly diagnosed and doubt cast on one of its putative apomorphies, with the development of a âpatellaâ considered a misinterpretation by the original authors.
Abstract: The first definitive ibaliid wasp (Cynipoidea: Ibaliidae) is described and illustrated from a female preserved in middle Eocene (Lutetian) Baltic amber. Archaeibalia succinica Liu & Engel gen. et sp.n. is distinct from all other members of the family, cladistically placed as sister to all other Ibaliidae, and classified in its own subfamily, Archaeibaliinae Liu & Engel subfam.n. The genus was putatively a parasitoid of wood-boring insects in hardwood trees. Given that the species is exceptionally rare in Baltic amber (a single individual) despite a habitat that would have placed it in immediate proximity with resin flows, the host of A. succinica was probably not living in the âBaltic amber treeâ. The historical biogeography and evolution of ibaliids is reconsidered based on the present paleontological evidence.
Abstract: A key is provided for the eleven species of Thrinchostoma Saussure (Halictinae: Halictini) known from Asia. A hitherto unknown male, apparently of Thrinchostoma (Thrinchostoma) afasciatum Michener, from Borneo is described and illustrated.
Abstract: The Tertiary genus Laasbium Scudder, originally described with two species and as a lineage of staphylinid beetles (Coleoptera: Staphylinidae) from the Eocene-Oligocene boundary of Florissant, Colorado, is re-evaluated. Examination of the original series for Laasbium agassizii Scudder (type species) and Laasbium sectile Scudder reveal that these represent incompletely preserved earwigs (Dermaptera). The genus Laasbium is transferred to the order Dermaptera and comments provided on the classification of Florissant fossil earwigs, all previously placed in the genus Labiduromma Scudder. A lectotype is designated for Laasbium agassizii and the following six new genera erected to accommodate the diversity of Florissant fossil earwigs (authorship of all taxa is Engel and Chatzimanolis): Petrolabis (type species:
Labiduromma gurneyi Brown), Litholabis (type species: Labiduromma gilberti Scudder), Rupiforficula (type species: Labiduromma scudderi Brown), Geroncolabis (type species: Labiduromma tertiaria Scudder), Spiladopygia (type species: Labiduromma exsultatum Scudder), and Paleocarcinophora (type species:
Labiduromma lithophila Scudder). The following new combinations are established: Petrolabis gurneyi (Brown), Litholabis gilberti (Scudder), Rupiforficula scudderi (Brown), Rupiforficula labens (Scudder), Rupiforficula inferna (Scudder). âLaasbiumâ sectile, a poorly-preserved lateral compression, is considered genus incertae sedis.
Abstract: Insects have evolved diverse methods of predator avoidance, many of which implicate complex adaptations of their wings (e.g., Phylliidae, Nymphalidae, Notodontidae). Among these, angiosperm leaf mimicry is one of the most dramatic, although the historical origins of such modifications are unclear owing to a dearth of paleontological records. Here, we report evidence of pinnate leaf mimesis in two lacewings (Neuroptera): Bellinympha filicifolia Y. Wang, Ren, Liu & Engel gen. et sp. nov. and Bellinympha dancei Y. Wang, Ren, Shih & Engel, sp. nov., from the Middle Jurassic, representing a 165-million-year-old specialization between insects and contemporaneous gymnosperms of the Cycadales or Bennettitales. Furthermore, such lacewings demonstrate a preangiosperm origin for leaf mimesis, revealing a lost evolutionary scenario of interactions between insects and gymnosperms. The current fossil record suggests that this enigmatic lineage became extinct during the Early Cretaceous, apparently closely correlated with the decline of Cycadales and Bennettitales at that time, and perhaps owing to the changing floral environment resulting from the rise of flowering plants.
Abstract: For nearly 100 million years the India subcontinent drifted from Gondwana until its collision with Asia some 50 Ma, during which time the landmass presumably evolved a highly endemic biota. Excavations of rich outcrops of 50-52 myo amber with diverse inclusions from the Cambay Shale of Gujarat, western India address this issue. Cambay amber occurs in lignitic and muddy sediments concentrated by near-shore chenier systems. It is a class II, cadinene-based polymer, which, along with fossil wood anatomy indicates a definitive source of Dipterocarpaceae. The amber is very partially crosslinked and polymerized, and readily dissolves in organic solvents, thus allowing extraction of whole insects, whose cuticle retains microscopic fidelity. Fourteen orders and more than 52 families and 100 species of arthropod inclusions have been discovered thus far, which show affinities to taxa from the Eocene of northern Europe but also to the Recent of Australasia, and the Miocene of tropical America. Thus, pre-contact India appears not as biologically isolated or insular as previously believed. A significant diversity of eusocial insects are fossilized, including corbiculate bees, rhinotermitid termites, and modern subfamilies of ants (Formicidae), groups that apparently radiated during the contemporaneous Early Eocene Climatic Optimum or just prior to it during the Paleocene-Eocene Thermal Maximum. Cambay amber preserves a uniquely diverse and early biota of a modern-type of broad-leaf tropical forest, revealing 50 Ma of stasis and change in biological communities of the dipterocarp primary forests that dominate southeastern Asia today.
Abstract: Among weevils of the subfamily Baridinae (548 extant genera and ca. 9,000 species), unique prosternal horns and associated sheaths have evolved independently multiple times. These structures are utilized in a unique form of male-male aggression in which males push, rather than overturn as in most other horned beetles, their competitor. Herein we report the first fossils of male Baridinae exhibiting such prosternal horns. Two males recovered from the middle Eocene Green River Formation in northwestern Colorado serve to provide a minimum age (at ca. 47 million years old) for both the origin of horns and its associated form of male-male combat in Baridinae.
Abstract: The fi rst Cretaceous fossil of the bostrichoid beetle family Anobiidae (Bostrichiformia: Bostrichoidea) is described and figured. Mesernobius anawrahtai gen. et sp. nov., is described from a single individual preserved in mid-Cretaceous (latest Albian) amber from Myanmar (Burma). The fossil intermingles many features respective to the subfamilies Eucradinae, Dryophilinae, and Ernobiinae, and is placed in its own subfamily Mesernobiinae subfam. nov. Pending a more complete cladistic investigation of higher relationships within Anobiidae, the new subfamily is tentatively considered more derived than Eucradinae owing to the produced and carinate lateral margin of the prothorax, but plesiomorphic to the remaining subfamilies owing to the rudimentary metacoxal plates and the absence of pectinate protarsi.
Abstract: Two species of Cretaceous amber Ripiphoridae (Tenebrionoidea) are attributable to the tribe Ripidiini (subfamily Ripidiinae), both in latest Albian amber â âRipiphorusâ burmiticus (Cockerell) from Myanmar and Paleoripiphorus deploegi Perrichot et al. from France. New information and interpretations are provided for each species and Cockerellâs species is officially placed in the tribe and within a new genus, Cretaceoripidius gen. nov. Revised diagnoses are provided for the subfamily Ripidiinae and its constituent tribes, Eorhipidiini and Ripidiini.
Abstract: The first damselfly in Late Cretaceous amber from South Dakota is described and figured. The specimen preserves the forewing apex of a putative hemiphlebiid, a group of relict damselflies today that were apparently widespread and diverse during the Cretaceous.
Abstract: The first termites in Early Cretaceous (Albian) amber from Spain are described and figured. Morazatermes krishnai Engel and Delclòs, new genus and species, is described from an imago (and wings of a second specimen) preserved in fossiliferous resin from Moraza, Burgos Province. A second termite species, Cantabritermes simplex Engel and Delclòs, new genus and species, is also recorded from the same deposits but is presently known only from the forewing. Similarly, an isolated forewing in amber from San Just, Teruel Province is described as Aragonitermes teruelensis Engel and Delclòs, new genus and species. Lastly, the first termite in Late Cretaceous (Campanian) amber from Grassy Lake, near Medicine Hat, Canada is described from a fragmentary imago lacking wings or much of the body. All of these taxa belong to a primitive grade of unassigned termites between Mastotermitidae and the families Termopsidae, Hodotermitidae, and Archotermopsidae (sensu Engel et al., 2009). Notes are appended on the recently described âKalotermesâ burmensis Poinar, from the latest Albian of Myanmar (Burmese amber), and the species transferred to Kachinitermopsis Engel and Delclòs, new genus, resulting in the new combination, Kachinitermopsis burmensis. These new taxa highlight the diversity of primitive termites during the Cretaceous.
Abstract: We review a series of related publications that combine higher-level phylogenies of weevils (Coleoptera: Curculionoidea) with host plant information to explain the success of this megadiverse lineage in the context of a co-evolutionary escape-and-radiation hypothesis. We argue that the authors' approach is marred by the cumulative effect of: (1) inadequate taxon sampling, particularly within the most diverse family Curculionidae; (2) insufficient reconciliation of systematic evidence, including the reassessment of morphological characters and necessary classificatory emendations; (3) exceedingly wide concepts of ecological similarity, leading to uninformative tests of adaptation; (4) insufficient resolution of the temporal sequence of associated weevil and angiosperm radiations; and (5) inadequate consideration of alternatives to the escape-and-radiation hypothesis. As a result, there are very few new and reliable inferences about the evolutionary success of weevils that depend precisely on the phylogenetic data presented in these studies. Improved taxon sampling alone is not the solution, because the existing mid-level classification of weevils is too deficient to permit inferences about natural lineages and their ancestral traits. We therefore recommend abandoning such an approach in favour of more narrowly focused reconstructions of the evolutionary history of generic and tribal groupings.
Abstract: Although caddisfly (Trichoptera) cases and adults are fairly abundant in the fossil record, fossils of the immature stages, particularly insights into the pupal stage, are exceedingly rare. Herein we report the discovery of a fossil caddisfly pupa, putatively of the family Vitimotauliidae, from Early Cretaceous deposits in northeastern China. This is the first fossil trichopteran pupa to have been described from China.
Abstract: Representatives of the family Strephocladidae have been considered as fossil relatives (i.e., stem-group) of Mantodea (mantises) based on characters of the forewing morphology. Here we describe new specimens from the Wellington Formation that we assign to the strephocladid species Homocladus grandis Carpenter, 1966. The range of morphological variation exhibited by the new material, in addition to wing morphology variability documented in extant mantises and roaches, suggest that H. ornatus Carpenter, 1966 and Paracladus retardatus Carpenter, 1966, reported from the same formation, are new junior subjective synonyms of H. grandis. We describe the first hind wing for this species based on a well-preserved specimen. It exhibits a combination of character states unique to dictyopteran insects.
Abstract: Multivariate morphometric analyses of Apis cerana Fabricius, 1793 across its full geographical range were performed. Principal components plots did not reveal distinct morphoclusters. Further substructuring of the principal component plots could not initially be derived but only by introducing local labelling did it reveal six main morphoclusters. We apply geographically based common epithets to the morphoclusters and designate them as: as âNorthern ceranaâ, âHimalayan ceranaâ âIndian plains ceranaâ âIndo-chinese ceranaâ âPhilippine ceranaâand âIndo-Malayan ceranaâ. A. cerana naturally occurs in climatic zones ranging from rainforest, savanna, steppe, grasslands and deciduous forest to taiga. The distributions of the morphoclusters are related to these physiographic and climatic factors. The taxonomy of A. cerana is formally revised and synonymous specific and infraspecific names summarized.-----Zusammenfassung: In diesem Artikel berichten wir über die Ergebnisse einer über das gesamte Verbreitungsgebiet reichenden multivariaten morphometrischen Analyse von Apis cerana und die statistisch definierten Morphokluster und Subklusterpopulationen innerhalb dieser. (1) Morphokluster I, ânördliche ceranaâ, erstreckt sich vom nördlichen Afghanistan und Pakistan durch das nordwestliche Indien über das südliche Tibet, das nördliche Myanmar, China und dann nordöstlich nach Korea bis zum fernöstlichen Russland und Japan; (2) Morphokluster II, âhimalaya ceranaâ schlieÃt die Bienen des nördlichen Indien und einige Regionen des südlichen Tibet und Nepal ein. (3) Morphokluster III âindische Ebene ceranaâ besiedelt die Ebenen des zentralen und südlichen Indien und Sri Lanka. (4) In Morphokluster IV, âindo-chinesische ceranaâ gruppieren sich die Bienen von Myanmar, Nordthailand, Laos und Südvietnam; (5) Morphokluster V âphilippinische ceranaâ ist auf die Philippinen beschränkt; (6) Morphokluster VI, hier als âindo-malayische ceranaâ bezeichnet, erstreckt sich von Südthailand über Malaysia und Indonesien. Wir stellen die Beziehungen der Morphokluster untereinander und ihre geophysikalischen und ökologischen Umgebungen dar und erstellen eine neue Verbreitungskarte auf Grudlage der gesamten über A. cerana publizierten Literatur (Hepburn and Hepburn, 2006). Einige Anmerkungen zu Genfluss und zeitlicher reproduktiver Isolation werden aus Daten zu Schwärmen und Wanderungen abgeleitet.
Nach moderner taxonomischer Praxis sind keine der historisch verwendeten âformellenâlateinischen Namen für die Variationen von Apis passend oder legitim. Daher sollten die Namen unter den Nomenklaturregeln ihrer Zeit gültig erstellten Namen sowie auch die übrigen, überwiegend nach 1970 erstellten Namen als Synonyme angesehen werden. Eine detaillierte synonymische Zusammenstellung im standardisierten taxonomischen Format findet sich bei Engel (1999). Als Konsequenz dieser publizierten Synonyme sind Trinomen wie A. c. japonica oder A. c. cerana unter den Regeln der ICZN keine offiziellen Bestandteile der Klassifikation von Apis mehr. Alle früheren Unterarten sind damit auÃer Gebrauch. Im gleichen Sinne sind Namen der Morphokluster wie âhimalaya ceranaâ und âindo-malayische ceranaâ wie wir sie hier gebrauchen nicht bindend, sie bieten Bienenwissenschaftlern aber eine weitere Möglichkeit, die zusammenhängenden Populationen von A. cerana sinnvoll und biologisch begründet zu unterteilen. Die ICZN Zusamenfassung der Taxonomie für A. cerana ist hier zusammen mit der formellen Synonymie der Unterartnamen und anderen Namen zusammengestellt, wie es von der Nomenklatur gefordert wird. Zuletzt soll angemerkt werden, dass A. cerana in das nordöstliche China, nach der Ambon Insel, Iran und papua-Neuguinea eingeführt wurde. Von dort hat sie Inseln in der TorresstraÃe besiedelt (Dunn, 1992) und in neuerer Zeit Neubritannien und die Salomoninseln erreicht (Anderson, 2005 â unpubl. data). A. cerana von Papua-Neuguinea sind morphologisch von denen aus Java nicht unterscheidbar. A. cerana wurde darüber hinaus mehrere Male in Darwin, Brisbane und nahe Perth, Australien aufgegriffen.
Abstract: A new species of the cleptoparasitic bee genus Chiasmognathus is described and figured from southwestern Niger. Chiasmognathus saheliensis sp. nov. (Ammobatini) is distinguished from its congeners by the combination of its coloration, integumental sculpturing (particularly that of the mesosoma), and genitalic structure. Species of the genus victimize nests of Nomioides and perhaps Ceylalictus (Halictidae: Halictinae: Nomioidini), both of which are known to occur in Niger.
Abstract: A new genus and species of dustywing is described and figured from Baltic amber. Geroconiocompsa ostara, new genus and species, is closely allied to Archiconiocompsa Enderlein (Coniopterygidae: Aleuropteryginae), itself known from a single Eocene amber species (Archiconiocompsa prisca Enderlein) and tentatively assigned to the Coniocompsini. The new genus shares with Archiconiocompsa the deeply forked forewing M, Cu forked near the wing base, two crossveins between Cu and A1, sc-r present in the forewing, Sc2 not joining Sc1 in the hind wing, and crossveins present between Cu1 and Cu2 and A1 and A2 in the hind wing, but has a more primitive form of venation in the connection of the posterior branch of Rs (R4+5) to the anterior branch of M (M1+2), the shorter distal abscissa of Sc1, and the hind wing r1-rs distad the Rs fork, features reminiscent of many Aleuropterygini. The new genus further bridges the morphological gap between Coniocompsini and Aleuropterygini highlighting that the former may render the latter paraphyletic. Archiconiocompsa prisca is figured from a newly recognized specimen in Baltic amber.
Abstract: Electrohemiphlebia barucheli gen. et sp. nov. and Jordanhemiphlebia electronica gen. et sp. nov., two new genera and species are described, based on exceptional inclusions of hemiphlebiid damselflies in Cretaceous amber from France and Jordan. The type specimen of E. barucheli was studied using phase contrast X-ray synchrotron microtomography, giving exceptional images and detailed information. Its comparison with the recent Hemiphlebia mirabilis confirms the attribution of several Cretaceous damselflies to the Hemiphlebiidae, showing that this particular group was widespread in the Early Cretaceous and probably originated in the Late Jurassic or earlier. The ecological niches today occupied by the small coenagrionoid damselflies were occupied during the Triassic and Jurassic by Protozygoptera, hemiphlebiids during the Early Cretaceous, and modern taxa in the Cenozoic.
Abstract: Albertoberotha leuckorum McKellar and Engel, a new genus and species of the neuropteran family Rhachiberothidae is described from Upper Cretaceous (Campanian) amber from the Grassy Lake locality in Alberta, Canada. Rhachiberothidae today consist of 13 species from sub-saharan Africa; but 12 species in amber throughout the Northern Hemisphere indicate that the family was global at least 125â45 mya. Despite the extent of existing studies pertaining to amber-entombed neuropterans, only members of the Berothidae and Chrysopidae have been conclusively reported from Canadian amber to date. We describe the first representative of the Rhachiberothidae to be observed in Campanian amber and draw comparisons with genera in other Cretaceous deposits.
Abstract: The Central American species of the rare bee genus Chlerogella Michener (Halictinae: Augochlorini) are revised. Aside from the previously described Chlerogella elongaticeps Michener and C. clidemiae Engel, five
new species are added to the fauna and figured as C. prolixa sp. n., C. fortunaensis sp. n., C. kellieae sp. n., C. anthonoma sp. n., and C. pinocchio sp. n. These species include the first records from Costa Rica (C. kellieae, C. anthonoma, and C. pinocchio) and the first description of the male for C. elongaticeps. A dichotomous key to the species is provided.
Abstract: Complex ethological adaptations and intraspecific interactions leave few fossil traces. We document three Dominican (20 million years old [myo]) and Baltic (45 myo) amber fossils that exhibit firm evidence of highly integrated interactions between mothers and offspring in the diverse camptosomate lineage of beetles (Chrysomelidae, leaf beetles). As in contemporary species, these hard cases were initially constructed by mothers, then inherited and retained by offspring, which then elaborate this protective domicile with an unusual but economical building material, their feces. The three fossils are classified in the Subfamily Cryptocephalinae; two are classified in the tribe Chlamisini based on morphological evidenceâthe flattened head lacking a sharp keel and long legs with simple recurved untoothed claws. These diagnostic features are not clearly visible in the third specimen to permit more refined identification. These fossils provide more precise paleontological dating of tribal nodes within the cryptocephaline radiation of leaf beetles. These fossils are the first and earliest evidence of motherâoffspring interaction, building behavior, and fecal recycling in Camptosomata beetles and of inheritance of architectural structures in beetles.
Abstract: A new orthognathine weevil species (Curculionoidea: Dryophthoridae), Mesocordylus longiscapus sp. n., is described and illustrated from Early Miocene Dominican amber. It represents the first amber fossil record of Mesocordylus and the second for the subfamily Orthognathinae.
Abstract: A new species of anthidiine bee (Megachilidae: Megachilinae: Anthidiini), Anthidiellum (Ranthidiellum) ignotum sp. n., is described and figured from northeastern Thailand, the furthest North this subgenus has yet been recorded. The species is distinguished from its congeners, being most similar to A. (R.) apicepilosum (Dover) in the coloration of the legs, but is otherwise quite unique for the group. A provisional key to the species of Ranthidiellum is provided.
Abstract: A new species of the termite bug genus Termitaradus Myers (Aradoidea: Termitaphididae) is described and figured based on a single female preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Termitaradus mitnicki sp. n. differs from the only other termitaphidid in Dominican amber, T. avitinquilinus Grimaldi and Engel, in the integumental ornamentation, number of laminae and lobules, body proportions, and setation. This is the third species of fossil Termitaphididae discovered. A revised key to living and fossil termitaphidids is provided.
Abstract: Caenaugochlora (Caenaugochlora) cyanella (Halictinae: Augochlorini), new species, is described and figured from females collected in northwestern Honduras. The new species, although belonging to the subgenus Caenaugochlora Michener, superficially resembles C. donnae Engel of the subgenus Ctenaugochlora Eickwort, both having a strong metallic blue coloration and distinctly tuberculate subpleural signum. Caenaugochlora cyanella, however, lacks the densely pectinate inner metatibial spur, strongly and completely striate basal area of the propodeum, densely punctured integument, and other features of Ctenaugochlora species. The species is distinguished from its congeners and characters for its recognition provided.
Abstract: A description of a new genus and species of braconid, Archephedrus stolamissus, from Early Cretaceous (Albian) amber from Moraza-PenËacerrada I (Spain) is here provided. This is the first fossil Aphidiinae described in Cretaceous amber. The fossil has some typical characters of the subfamily but possesses a unique assemblage of characters among aphidiines, such as a fairly robust abdomen, with a more pronounced articulation between the first and second, instead of the second and third, metasomal segments, as well as several wing venational traits. The distribution of this and other aphidiine fossils, as well as their putative phylogenetic placement as basal among Aphidiinae, is discussed, supporting a Northern rather than Southern Hemisphere origin for the lineage.
Abstract: Two new halictine bees (Halictidae: Halictinae) are described and figured from females preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Oligochlora semirugosa sp. n. (Augochlorini) is similar to O. micheneri Engel but differs in the shape of the pronotal dorsolateral angle, the partially rugulose gena (entirely imbricate in the latter species), and the sculpturing of the face, mesosoma, and metasomal terga. Nesagapostemon moronei gen. n. sp. n. (Caenohalictini) resembles Eickwortapis in the absence of carinae bordering the dorsal horizontal surface of the propodeum while having the vertical posterior surface encircled. The genus differs from Eickwortapis in the much larger and more robust body size (nearly twice as large), the non-slanting and shorter horizontal surface of the propodeum, sculpturing, and pilosity of the hind legs. A second specimen of O. grimaldii Engel is recorded and a provisional key to halictid bees in Dominican amber is provided.
Abstract: Two new species of Old World cleptoparasitic bees are described and figured from Saudi Arabia, the United Arab Emirates, and Egypt, both of the genus Ammobates Latreille (Nomadinae: Ammobatini). Ammobates androsthenes Engel, new species (United Arab Emirates and Saudi Arabia), and A. arsinoe Engel, new species (Egypt), are distinguished from their congeners.
Abstract: The first fossil snakefly from the Neogene of North America (mid-Miocene of Nevada) is described and figured. Agulla mineralensis Engel, new species, is represented by an isolated hind wing and is more similar to modern Nearctic snakeflies in venation than to most Old World species in contrast to some of the Paleogene species which seem to represent a different faunal composition.
Abstract: Like ants, termites are entirely eusocial and have profound ecological significance in the tropics. Following upon recent studies reporting more than a quarter of all known fossil termites, we present the first phylogeny of termite lineages using exemplar Cretaceous, Tertiary, and Recent taxa. Relationships among Recent families were largely unaffected by the addition of extinct taxa, but the analysis revealed extensive grades of stem-group taxa and the divergence of some modern families in the Cretaceous. Rhinotermitidae, Serritermitidae, and the âhigherâ termites (family Termitidae), which comprise 84% of the world termite species, diverged and radiated entirely in the Tertiary, corresponding with significant increase of termite individuals in the fossil record. Radiation of the higher termites may have affected the formation of terrestrial carbon reserves like oil and coal. The higher classification of Isoptera is slightly revised based on the phylogenetic results. The following new taxa are proposed: Cratomastotermitidae, new family; Euisoptera, new clade; Archotermopsidae, new family; and Neoisoptera, new clade. In addition, the families Stolotermitidae, Stylotermitidae, and Archeorhinotermitidae are newly recognized or resurrected, and the families Termopsidae and Hodotermitidae are significantly restricted in composition.
Abstract: Aside from pollen and nectar, bees of the subfamily Megachilinae are closely associated with plants as a source of materials for nest construction. Megachilines use resins, masticated leaves, trichomes and other plant materials sometimes along with mud to construct nests in cavities or in soil. Among these, the leafcutter bees (Megachile s.l.) are the most famous for their behaviour to line their brood cells with discs cut from various plants. We report on fossil records of one body fossil of a new non-leafcutting megachiline and of 12 leafcuttings from three European sitesâEckfeld and Messel, both in Germany (Eocene), and Menat, France (Paleocene). The excisions include the currently earliest record of probable Megachile activity and suggest the presence of such bees in the Paleocene European fauna. Comparison with extant leafcuttings permits the interpretation of a minimal number of species that produced these excisions. The wide range of size for the leafcuttings indirectly might suggest at least two species of Megachile for the fauna of Messel in addition to the other megachiline bee described here. The presence of several cuttings on most leaves from Eckfeld implies that the preferential foraging behaviour of extant Megachile arose early in megachiline evolution. These results demonstrate that combined investigation of body and trace fossils complement each other in understanding past biodiversity, the latter permitting the detection of taxa not otherwise directly sampled and inferences on behavioural evolution.
Abstract: The fossil history of leaf beetles (Chrysomelidae) is relatively poorly documented despite an abundance of available material. Of particular interest is the origin and radiation of the diverse tortoise beetles, a derived group within Cassidinae s.l. (=Cassidinae + Hispinae) defined by the exophagous life history and specialized morphology of the immature stages. Cassidinae is also a group with relatively few fossil records that can be assigned with any degree of certainty. Here we report two of the oldest definitive tortoise beetle fossils, Eosacantha delocranioides gen.n. et sp.n. and Denaeaspis chelonopsis gen.n. et sp.n., from the Eocene Green River Formation (ca. 47 million years old) in northwestern Colorado, U.S.A. Owing to the fine level of preservation, many important features can be observed and are coded into the recent cladistic analysis for the subfamily. Phylogenetic analysis highlights that both genera have affinities with modern lineages, one restricted to the Old World and the other restricted to the Neotropics. Although Cassidinae as a whole extend into the Cretaceous, the available information suggests that the tortoise beetles perhaps originated and diversified during the Early Tertiary. As such, the morphological and biological transitions from the leaf-mining hispiforms to the distinctive tortoise-like cassidiforms, with their elaborate defensive larval shields and other unique behaviours, probably took place during the latest Paleocene or earliest Eocene. These Green River fossils are the oldest yet to document the specialized morphology associated with the transition in cassidine feeding and immature biology.
Abstract: An enigmatic new genus and species of rove beetle (Coleoptera: Staphylinidae) is described as Dolichoxenus newtoni, new genus and species, in Early Miocene (Burdigalian) amber from the Dominican Republic. The species is the first oxyteline discovered as an amber inclusion. The genus is apparently a member of the tribe Oxytelini (Staphylinidae: Oxytelinae) and may be allied to the African genus Jerozenia Herman, 2003. The genus exhibits several remarkable apomorphies for the subfamily, and in general possesses features otherwise known in the subfamily for inquilines of ants, suggesting a possible paleobiological association for the genus.
Abstract: Caupolicana (Zikanapis) wileyi sp. n. from Guatemala is described. New locality records are noted for other species, and the hitherto unknown female of C. (Z.) rozenorum Michener, Engel, and Ayala from Guatemala is described. A key for the identification of Central American Caupolicana is provided.
Abstract: Aim---This study aimed to evaluate the probability of suitable habitats in the United States for two adventive orchid bee species (Eulaema polychroma (Mocsáry) and Euglossa viridissima Friese), one of which has become established in southern Florida despite the absence of its associated orchid hosts.
Location---North and Central America, northern South America, and the Caribbean.
Methods---Using positive occurrence data within the native range of both orchid bee species, Maxent species distribution modelling was employed to evaluate the probability of suitable habitats in the United States. The power of predictability for the model was tested using partitions of the data.
Results---Our results show the absence of suitable habitat in southern Arizona for E. polychroma to maintain populations there, as well as establishing the northernmost limit for the species at around 29° N in northwestern Mexico. Suitable habitat was found for E. viridissima in various locations throughout southern Florida. This species is predicted to spread to occupy roughly the southern half of the Florida Peninsula.
Main conclusions---The findings indicate that species distribution modelling is useful for evaluating records of species occurrence outside of their native range. Our results indicate that the isolated record of a male of E. polychroma from southern Arizona should not be considered representative of an established population in the absence of further males and females from the same region. Conversely, E. viridissima has successfully become established in southeastern Florida after a seemingly accidental introduction first noticed in the summer of 2003. We discuss the naturalization of E. viridissima in Florida, the probability of suitable habitat across the Caribbean (where orchid bees are otherwise natively absent today), and the absence of perfume orchids (Orchidaceae). Lastly, we discuss the implications of these results for understanding the biology and biogeography of Euglossini.
Abstract: A giant termite is described and figured from the Late Miocene of the Styrian Basin in southeastern Austria. Gyatermes styriensis gen. n. et sp. n. is represented by a relatively complete forewing, with basal scale. The fossil approximates in size the largest of all termites today and is the largest fossil termite on record. The presence of this species in the Late Miocene fauna of Europe indicates that climatic conditions were appropriate for the persistence of species and colonies requiring relatively stable, warm conditions. The genus is primitive in overall features but shares some similarity with the dampwood termites.
Abstract: The purpose of this application is to emend the family-group name NOMIIDAE Gozis, 1875 (Insecta, Coleoptera), a senior homonym of NOMIINAE Robertson, 1904 (Insecta, Hymenoptera) and long-considered a synonym of PSYDRINA LeConte, 1853, thereby removing the homonymy between the two names. It is proposed that the stem of the generic name Nomius Laporte, 1835, on which the beetle family-group name is based, be emended to give NOMIUSIDAE, while leaving the bee name (based on Nomia Latreille, 1804) unaltered.
Abstract: The extinct, parasitoid wasp family Stigmaphronidae (Proctotrupomorpha: Ceraphronoidea) is reviewed and a cladistic analysis of relationships undertaken. Stigmaphronids are presently known principally in Cretaceous amber from Siberia, Alaska, Canada, New Jersey, Myanmar, and Lebanon, but also from a few compressions from the Early Cretaceous of Siberia and Mongolia. As a result of the study the following new taxa are proposed, more than doubling the size of the family: Elasmophron kurthi nov. gen. et spec. (New Jersey amber), Libanophron astarte nov. gen. et spec. (Lebanese amber), Burmaphron nov. gen., Burmaphron tridentatum nov. spec. (Burmese amber), B. prolatum nov. spec. (Burmese amber), Tagsmiphron nov. gen., Tagsmiphron muesebecki nov. spec. (New Jersey amber), T. gigas nov. spec. (New Jersey amber), T. ascalaphus nov. spec. (New Jersey amber), and T. canadense nov. spec. (Canadian amber). The genus Elasmomorpha KOZLOV is proposed as a junior synonym of Allocotidus MUESEBECK (nov. syn.) resulting in Allocotidus melpomene (KOZLOV) nov. comb. Relationships are well supported, so the lack of any stratigraphic-clade rank correlation strongly suggests poor stratigraphic sampling of what was probably a very diverse lineage.
Abstract: Bees of the genus Chiasmognathus (Ammobatini) occurring in the Arabian Peninsula are revised. Three species, all new, are recognized as: Chiasmognathus nearchus n. sp. (from the UAE and Oman), C. aurantiacus n. sp. (from the UAE), and C. himyarensis n. sp. (from Yemen). Species are cleptoparasitic on the halictid bee genus Nomioides and likely also on Ceylalictus (Halictinae: Nomioidini). The host of C. nearchus n. sp. is Nomioides rotundiceps Handlirsch, 1888.
Abstract: Males of solitary bees usually spend the night in clusters on small branches of plants, cavities and flowers. The individuals usually return to the same location each evening during their life, exhibiting site fidelity to a particular plant. The present paper reports the sleeping roosts of the males of some oil-collecting bees of the genera Centris, Paratetrapedia, Lanthanomelissa, Monoeca and Tetrapedia.
Abstract: The first fossil honey bee (Apini: Apis Linnaeus) from the New World is described and figured, expanding the former native range of the tribe Apini into the Western Hemisphere. Apis nearctica sp. nov., is represented by a single female worker preserved in paper shale from the middle Miocene of Stewart Valley, Nevada. The species belongs to the armbrusteri species group (= Cascapis Engel) and is most similar to the extinct species A. armbrusteri Zeuner from the Miocene of southwestern Germany. The species is described and its affinities discussed, as well as its implications for our understanding of honey bee and corbiculate bee biogeography and evolution.
Abstract: A new genus and species of the extinct Paleozoic insect order Diaphanopterodea (Palaeodictyopterida) is described and figured from the Early Permian (Artinskian) Wellington Formation of Noble County, Oklahoma. Anomalohymen dochmus, new genus and species, is most similar to Biarmohymen bardense Zalessky from the Early Permian (Kungurian) of Tshekarda in Russia. The two genera share the proximal coalescence of M and CuA along with a generally reduced venation. Rather than erect another monogeneric family, we here include Anomalohymen in the Biarmohymenidae, emending the diagnosis of the family, providing a key to the constituent genera, and extending the biogeographic and temporal range of the lineage.
Abstract: A second species of dasyleptid bristletail (Archaeognatha: Dasyleptidae) is described and figured from the Lower Permian Wellington Formation of Kansas. Dasyleptus artinskianus Engel, new species, is distinguished from other dasyleptids and a key to the species of the genus is provided.
Abstract: The first tiphiid wasp (Aculeata: Euaculeata: Vespoidea: Tiphiiformes) in Cretaceous amber is described and figured. Thanatotiphia nyx, new genus and species, is represented by a male entombed in mid-Cretaceous (latest Albian) amber from Myanmar. Thanatotiphia possesses remarkable apomorphies in wing venation, lacks key traits of modern subfamilies, and is thus classified in a new subfamily, Thanatotiphiinae. The fossil is further shown to be nested well within the family, indicating that major lineages of Tiphiidae diverged by the mid-Cretaceous. The new taxon is compared with modern tiphiid subfamilies and the sparse fossil history of the family briefly overviewed.
Abstract: Notes are provided on the identity and nomenclature of Amegilla sesquicincta (Erichson), a name long confused in its application. Amegilla sesquicincta is a Senegalese species of uncertain identity while the species from India to which this name has been applied is preoccupied and accordingly named A. dizona nom. n. As this name was used as the type species of the subgenus Dizonamegilla, the question of the type species for this group is addressed and subsequently fixed as A. dizona in accordance with ICZN regulations.
Abstract: The first fossil of the pteromalid subfamily Leptofoeninae Handlirsch is documented. Leptofoenus pittfieldae sp. n. is described and figured from a single male preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. The fossil is compared with its modern congeners and comments generally provided on the taxonomy of the subfamily, including a key to the two genera.
Abstract: A new species of the highly specialized hemipteran family of social ectosymbionts, the Termitaphididae, is reported in Miocene amber from the Dominican Republic: Termitaradus avitinquilinus, n. sp. It differs from the only other fossil termitaphidid (Termitaradus protera Poinar and Doyen), in Miocene Mexican amber, and from modern species by various distinctive features. Two of the three specimens of T. avitinquilinus are preserved in a piece of amber with its presumed host, a worker of the basal termite, Mastotermes electrodominicus Krishna and Grimaldi. The hypothesis that the family Termitaphididae is ancient and inhabited Pangaea is disputed in favor of a much more recent, Tertiary origin. It is suggested, in fact, that termitaphidids are highly modified Aradidae, possibly derived from the Mezirinae.
Abstract: A new high-elevation species of the augochlorine bee genus Augochloropsis Cockerell (Anthophila: Apoidea: Halictidae: Halictinae: Augochlorini) is described and figured. Augochloropsis (Paraugochloropsis) isabelae, new species, is distinguished from its congeners and it is noted that females of the species exhibit head size variation. The variation in head size and morphology seen between females is suggestive of social behavior in this species. Where known, species of Augochloropsis range from solitary to semisocial, and there is even a single record of primitive eusociality in the genus.
Abstract: Publishing taxonomic and systematics studies in the digital era faces major challenges and requires new approaches, many of which are currently stimulating spirited discussions among taxonomists and systematists. New amendments to the International Code of Zoological Nomenclature are expected to regulate electronic publishing of new taxa and create a standard form for their registration (ZooBank). Responding to a perceived need, this editorial announces establishment of ZooKeys - a new online and print journal in zoological taxonomy and systematics, which aims to quickly respond and adapt to the newest developments in taxonomic publishing. Open Access is accepted as mandatory for ZooKeys. The rationale for and concept of ZooKeys is discussed in detail.
Abstract: The first formally described fossil of the beetle family Prostomidae (Tenebrionoidea) is presented. Vetuprostomis consimilis n.gen. et n.sp., is described and figured from a single individual preserved in mid-Cretaceous amber from Myanmar (Burma). The fossil is remarkably similar to modern prostomids from which it is distinguished. The only other records of fossil jugular-horned beetles are three undescribed Baltic amber inclusions in a private collection.
Abstract: A fossil cimicoid bug is described and figured from a single male preserved in mid-Cretaceous (latest Albian) amber from Myanmar. Quasicimex eilapinastes n.gen., n.sp., shares many features with the bed bug family Cimicidae (Cimicomorpha: Cimicoidea), as well as a few features of primitive cimicids such as Primicimicinae, while simultaneously retaining some significant plesiomorphies relative to crown-group cimicids. The genus is tentatively retained in Cimicidae s. lato, basal to all other cimicids.
Abstract: A new species of fig wasp, Ceratosolen (Ceratosolen) polyodontos n. sp., is described from females captured at Los Baños, Luzon, Philippines. The species can be distinguished from its congeners by the possession of a much greater number of ventral mandibular lamellae (22â23), divided into an anterior and posterior area, and posterior metasomal structures associated with the ovipositor.
Abstract: A new morphological structure is described and figured for orchid bees (Apinae: Euglossini). These minute features are located posterolateral to the ocelli and are termed âjuxtocellar structuresâ. The diversity of their form across Euglossini is described. Homologous structures were found in some related lineages of apid bees (e.g., Anthophorini, Centridini, Eucerini) while in others the structures were absent (e.g., Xylocopinae, Nomadinae). Most notably juxtocellar structures are apomorphically lost in all other corbiculate apine tribes (i.e., Bombini, Meliponini, Apini, Electrobombini, Electrapini, and Melikertini), a pattern which is in accordance with current phylogenetic hypotheses for the clade.
Abstract: A new genus and species of primitive termite (Isoptera) is described and figured from the remains of an imago preserved in middle Eocene (Lutetian) Baltic amber. Idanotermes desioculus Engel, new genus and species (near to Mastotermitidae), is distinguished from related genera as well as all other termites known as inclusions in Baltic amber. In addition, the genus Heterotermes (Rhinotermitidae: Heterotermitinae) is newly recorded from Baltic amber and Heterotermes eocenicus Engel, new species, is described. A revised key to Baltic amber termites is provided so as to accommodate the newly discovered species.
Abstract: The termite species from Brazil's Early Cretaceous (Aptian-aged) Crato (Santana) Formation are evaluated on the basis of the degree of character variation seen in modern species, using a series of 56 specimens, scanning electron microscopy of minute structures, and a bivariate plot of the proportional sizes of sclerotized body structures. Of the previously described species only the following are considered valid: Mariconitermes talicei Fontes and Vulcano, Meiatermes araripena Krishna, Cratomastotermes wolfschwenningeri Bechly, Cratokalotermes santanensis Bechly, and Cretarhinotermes novaolindense Bechly. The combination M. araripena Krishna (once placed in Cretatermes) is restored, and Cretatermes pereirai Fontes and Vulcano is proposed as a junior synonym of M. araripena. The following new species is described: Meiatermes hariolus Grimaldi, new species. The following are considered nomina dubia based on superficial and even contradictory diagnoses: Caatingatermitinae Martins-Neto et al. (likely synonymous with Hodotermitinae); Araripetermes nativa Martins-Neto et al. (nomen incorrectum, recte: nativus), Caatingatermes megacephalus Martins-Neto et al., and Nordestinatermes obesa Martins-Neto et al. (nomen incorrectum, recte: obesus). These are probably all new synonyms of the Cretaceous genus Meiatermes Lacasa-Ruiz and MartÃnez-Delclòs and of M. araripena in particular, but this assertion cannot be verified without access to the type specimens. Of the six definitive species of Crato termites, reconstructions are provided for four. All species appear to be basal taxa, either a stem group to Isoptera, to Hodotermitidae sensu lato, or to Kalotermitidae. Despite very partial preservation, Cretarhinotermes appears to be within the hodotermitid grade and not a rhinotermitid. Some specimens have yielded detailed preservation of soft internal tissues, including the midgut, which has further phylogenetic implications.
Abstract: The first Cretaceous fossil of the wasp family Rhopalosomatidae (Aculeata: Euaculeata: Vespoidea) is described and figured from a male preserved in Burmese amber. Eorhopalosoma gorgyra Engel, new genus and species, is the first rhopalosomatid discovered in amber and the second â but first definitive â member of the family from the Cretaceous. The new species is distinguished from its modern counterparts. The modern genus Olixon Cameron is transferred to a separate new subfamily, Olixoninae.
Abstract: A family of extinct lacewings is described and figured from the Yixian Formation [Early Cretaceous (M.S.E.) or latest Jurassic (D.R.)] of Liaoning Province, China. Aetheogrammatidae Ren and Engel, new family, is established for Aetheogramma speciosa Ren and Engel, new genus and species, and is distinguished from other myrmeleontiform families. The enigmatic kalligrammatid genus Kallihemerobius Ren and Oswald is placed in a new subfamily, Kallihemerobiinae Ren and Engel.
Abstract: A new crabronid wasp species, Pison menkei sp. n., is described and figured from a single female preserved in Early Miocene (Burdigalian) Dominican amber. The fossil is herein distinguished from extant and extinct congeners and regarded as an isolated species removed from modern Neotropical species groups. It is the seventh named fossil Pison and the second from Dominican amber.
Abstract: Four new cleptoparasitic bees of the tribe Ammobatini (Apidae: Nomadinae) are described and figured from southeastern Pakistan and Sri Lanka. Ammobates maxschwarzi sp. n. (Pakistan) is known from a series of females, while A. cinnamomeus sp. n. (Pakistan), Parammobatodes craterus sp. n. (Pakistan), and Chiasmognathus taprobanicola sp. n. (Sri Lanka) are known from males and females. The species are distinguished from their congeners and comments made on potential hosts. In addition, C. gussakovskii (Popov), previously known only from Tajikistan, is newly recorded from southern Kyrgyzstan.
Abstract: A new fossil antlion, Choromyrmeleon aspoeckorum n.sp., is described and illustrated from the Yixian Formation (conservatively considered as Early Cretaceous or latest Jurassic) of Liaoning Province, China. This constitutes the second species of the genus Choromyrmeleon as well as the second fossil record of Myrmeleontidae from China.
Abstract: Well-preserved insects are reported in pelitic sediments from the Feldbach and Paldau Formation (Late Miocene: Early Pannonian) of the Styrian Basin, Austria. Herein we provide a brief overview of the hitherto recovered fauna. The fauna includes representatives of five insect orders, representing at least 10 morphospecies of the families Phrygaenidae (Trichoptera), Tipulidae (Diptera), putative Rhagionidae (Diptera), Carabidae and Chrysomelidae (Coleoptera), Formicidae (Hymenoptera), and a giant primitive termite near Termopsidae (Isoptera). The various identifiable morphospecies recovered to date are summarized.
Abstract: A new species of the rare cleptoparasitic bee genus Chiasmognathus Engel (Ammobatini) is described and figured from a female collected in northwestern Iran. Chiasmognathus rhagae sp. n. is generally similar to C. orientanus (Warncke) (Bulgaria, Turkey, Cyprus, Crete, and the Levant) or C. pashupati Engel (from southeastern Pakistan) but can be readily recognized by coloration and integumental sculpturing. In addition, a new locality in Israel is provided for C. aegyptiacus (Warncke).
Abstract: A new species of leaf-cutter bee, Megachile (Eutricharaea) ventrisi sp. n., is described and figured from western Saudi Arabia. The species is remarkably similar to M. walkeri Dalla Torre from the same region but differs strikingly in the structure of the metafemoral setae, metasomal scopa, and clypeal integument.
Abstract: A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in a single piece of middle Eocene (Lutetian) Baltic amber. Ctenoplectrella gorskii Engel, sp. n. is distinguished from other species of the genus most notably in the venation of the forewing.
Abstract: The remains of a new species of zorapteran (Polyneoptera: Anartioptera: Mystroptera: Zoraptera) are described and figured from a female preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Zorotypus (Zorotypus) mnemosyne Engel sp. n. is represented by a female of the apterous, blind morph (âapteronâ) and can be readily distinguished from the only other Miocene zorapterans, Z. goeleti Engel & Grimaldi (winged morph) and Z. palaeus Poinar (apterous morph) in the terminal abdominal structure, the shape of the cerci, and the spination of the metafemora. Notes on the status of the recently described Jordanian amber (contemporaneous with Lebanese amber) zorapteran are provided and the genus Paleospinosus is newly synonymized with Octozoros Engel (new synonymy) resulting in the new combination Z. hudae (Kaddumi). In addition, the name âZ. confirmans Schevenâ is considered a nomen nudum et invalidum. However, the taxon is distinct from other Dominican amber species and is therefore validated as Z. absonus Engel sp. n. and distinguished from other fossil zorapterans.
Abstract: A new genus and species of the peculiar braconid wasp subfamily Masoninae is described and figured from a female preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Anoblepsis konokeraia Engel and Bennett, new genus and species, belongs to the tribe Masonini but differs from the hitherto only known genus, Masona van Achterberg. The genus is diagnosed and compared with its modern counterparts. Anoblepsis konokeraia is the third braconid species documented from Dominican amber and the second of the subfamily Masoninae.
Abstract: The presence of an adventitious distal abscissa in the forewing venation of honey bees is recorded. The vein arises from the posterior quarter of the second [sic: third] submarginal cell, on the apical surface of the 2rs-m crossvein. The homology of this vein is discussed and its presence broadly compared across Hymenoptera so as to establish its correct identity. Based on the overall homology of hymenopteran wing venation it is concluded that this is a reacquisition of the vein "Rs2" and we accordingly tentatively term it "aRs2". The aRs2 was found in both Apis cerana Fabricius and A. mellifera Linnaeus at moderate frequencies, although it predominantly occurs in northeast Asian populations of the former. Species of the giant honey bees (Megapis) and dwarf honey bees (Micrapis) were found to lack the vein entirely, while the vein was found at low levels in other Asian lineages (Apis s.str.). The predilection to possess the vein appears to be a trait supporting the cavity-nesting honey bee clade (Apis s.str.).
Notes: Note an error in the abstract which refers to the "second" submarginal cell but should in fact refer to the "third" submarginal cell.
Abstract: New lacewings (Neuroptera) and snakeflies (Raphidioptera) are reported in Cretaceous ambers from Myanmar (Albian-Cenomanian), New Jersey (Turonian), and Canada (Campanian). Those newly reported and described in Burmese amber comprise the most species of any Cretaceous amber deposit, including a remarkable diversity of beaded lacewings (Berothidae) and the first Cretaceous amber alderfly (Megaloptera: Sialidae). The newly reported diversity includes: Jersiberotha myanmarensis sp. n. (Berothidae); Jersiberotha tauberorum sp. n. (Berothidae); Iceloberotha kachinensis gen. et sp. n. (Berothidae); Iceloberotha simulatrix sp. n. (Berothidae); Haploberotha persephone gen. et sp. n. (Berothidae); Telistoberotha libitina gen. et sp. n. (Berothidae); Systenoberotha magillae gen. et sp. n. (Berothidae); Dasyberotha eucharis gen. et sp. n. (Berothidae); Ethiroberotha elongata gen. et sp. n. (Berothidae); a beaded lacewing larva (Berothidae); Scoloberotha necatrix gen. et sp. n. (Rhachiberothidae); Litopsychopsis burmitica gen. et sp. n. (Psychopsidae); a silky lacewing larva (Psychopsidae); a putative first-instar silky lacewing larva (Psychopsidae); Elenchonymphes electrica gen. et sp. n. (Nymphidae); an osmylid lacewing larva (Osmylidae); and a fragmentary alderfly (Megaloptera: Sialidae). In New Jersey amber is described a new thorny lacewing, Rhachibermissa phenax sp. n. (Rhachiberothidae), while from Canadian amber are reported an egg and first instar of a green lacewing (Chrysopidae), the fragmentary remains of a beaded lacewing distinct from Plesiorobius but left unassigned (Berothidae), and a fragmentary larva of a mesoraphidiid snakefly (Raphidioptera: Mesoraphidiidae). The subfamily Paraberothinae is newly synonymized with Rhachiberothinae (syn. n.). The neuropterid fauna of Burmese, New Jersey, and Canadian amber is briefly summarized.
Abstract: The fossil crown wasp Electrostephanus petiolatus Brues comb. rev. (Stephanidae: Electrostephaninae) is redescribed from a single male preserved in middle Eocene Baltic Amber. The holotype was lost or destroyed around the time of World War II and subsequent interpretations of its identity have been based solely on the brief descriptive comments provided by Brues in his original account. The new specimen matches the original description and illustration provided by Brues in every detail and we hereby consider them to be conspecific, selecting the specimen as a neotype for the purpose of stabilizing the nomenclature for this fossil species. This neotype exhibits a free first metasomal tergum and sternum, contrary to the assertion of previous workers who indicated these to be fused. Accordingly, this species does indeed belong to the genus Electrostephanus Brues rather than to Denaeostephanus Engel & Grimaldi (Stephaninae). Electrostephanus petiolatus is transferred to a new subgenus, Electrostephanodes n. subgen., based on its elongate pseudo-petiole and slender gaster, but may eventually warrant generic status as the phylogenetic placement of these fossil lineages continues to be clarified. A revised key to the Baltic amber crown wasps is provided.
Abstract: A fossil micropterigid moth (Zeugloptera: Micropterigoidea) is described and figured from a well preserved forewing of the Fur Formation [âMo-clayâ: earliest Eocene (Early Ypresian)] of Denmark. Moleropterix kalbei nov. gen. et nov. sp. is distinguished from other fossil micropterigids as well as modern counterparts.
Abstract: Cretopiesma suukyiae, new genus and species, is described, based on a unique female specimen in mid-Cretaceous (c. 100 myo) amber from northern Myanmar. Features of C. suukyiae unique for the small Recent family Piesmatidae include a long, protrudent clypeus, a dorsal carina of the head, lack of "jugal" lobes/appendices, widely separated coxae, very large scutellum, and the venation of the corium; some of these are plesiomorphic and shared with Aradidae. C. suukyiae possesses among the cuticular areolation and propleural cavities distinctive to Piesmatidae. Phylogenetic analysis of Recent and fossil genera of piesmatids resulted in a cladogram with Cretopiesma as sister group to the remainder of the family. Relationships of this unusual species and of Piesmatidae within Pentatomomorpha are discussed.
Abstract: Two new genera and species of snakeflies (Raphidioptera) are described and figured from the Jurassic Jiulongshan Formation of eastern Inner Mongolia, China. Ororaphidia megalocephala, new genus and species, and Styporaphidia magia, new genus and species, are both differentiated from other Mesozoic snakefly lineages. These constitute the oldest records of snakeflies from China.
Abstract: The first Dominican amber fossil of the parasitoid family Orussidae (Euhymenoptera: Orussomorpha) is described and figured from a single individual preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Ophrynopus peritus Engel, new species, is the first orussid fossil described from Tertiary amber and the first species documented from the West Indies.
Abstract: Specimens of Paleozoic Coleoptera are quite rare, particularly so in North America where they have been hitherto represented by a single specimen. The first Permian beetle from North America was only recently described from a single specimen of a complete elytron (no counterpart). A second specimen from another locality in those same beds, comprised of the part and counterpart of a fragment of an elytron, is figured and discussed here. While representing a somewhat larger individual than the original specimen, the present material appears to represent the same species, Permocoleus wellingtonenesis Lubkin and Engel.
Abstract: The morphology of the enigmatic, Mesozoic, aquatic insect family Chresmodidae is redescribed and its phylogenetic affinities among the polyneopterous orders discussed. Study of the complete venation of both fore- and hind wings observed in some specimens from the Spanish Barremian, permit us to postulate the hypothesis that the family belongs to the Archaeorthoptera, thus to the orthopteroid lineage rather than to crown-group Phasmatodea or to the more inclusive group Holophasmatodea (sensu Grimaldi & Engel, 2005). New specimens from Spain, Lebanon, Brazil, and Germany permit a new re-description of some chresmodid body structures, with concomitant implications for the phylogenetic position of the family. Chresmoda neotropica n. sp. is described from the Aptian-Albian of the Crato Formation (northeast Brazil). The functional morphology proposed for some of their specialized structures suggest a new hypothesis of Chresmoda palaeobiology, and related to this some implications for the localized palaeoenvironment as well as global palaeoclimate.
The problematic Sternarthron spp. from the Upper Jurassic of Solnhofen were described as probable palpigrades (Arachnida: Palpigradi), based on type material originally thought to be fossil insects. The affinities of Sternarthron Haase, 1890 have been questioned. Our restudy of Haaseâs types clearly indicates that these fossils represent nymphal specimens of chresmodids. Consequently, Sternarthron has to be considered as a junior synonym of the fossil insect genera Propygolampis Weyenbergh, 1874 and Chresmoda Germar, 1839.
Abstract: A new species of the cleptoparasitic bee genus Chiasmognathus Engel (Nomadinae: Ammobatini), a lineage of minute Anthophila victimizing Nomioides Schenck (Halictidae: Halictinae: Nomioidini), is described and figured from Sindh Province, Pakistan. Chiasmognathus pashupati Engel, new species, is distinguished from previously described congeners and is a cleptoparasite of Nomioides patruelis Cockerell.
Abstract: Those weevils belonging to the subfamily Cossoninae occurring in Early Miocene (Burdigalian) amber from the Dominican Republic are described and figured. The fauna includes 10 species (nine new): Micromimus orcus spec. nova, Caulophilus ashei Davis & Engel, C. falini spec. nova, C. swensoni spec. nova, C. bennetti spec. nova, Dryotribus amplioculus spec. nova, Paralicus abnormis spec. nova, Proeces longirostrum spec. nova, Stenotrupis breviscapus spec. nova, and Cossonus hinojosai spec. nova.
Abstract: A new bee species of the genus Amegilla (Apinae: Anthophorini) is described and figured from northeastern Egypt. Amegilla argophenax spec. nova, belongs to the fasciata group and is most similar to A. deceptrix (Priesner) comb. nova which occurs in the same region. Characters are provided to distinguish the species from its congeners. Podalirius pyramidalis Kirby, from Socotra (Republic of Yemen), is resurrected from synonymy under Amegilla albigena (Lepeletier de Saint Fargeau) (as A. pyramidalis comb. nova) where it is, like A. argophenax and A. deceptrix, a member of the fasciata group.
Abstract: A brief overview and dichotomous key is provided for those termites (Isoptera) occurring in middle Eocene (Lutetian) Baltic amber. Ten species in seven genera are presently documented from Baltic amber, these being as follows: Garmitermes succineus n. gen. n. sp., Termopsis bremii (Heer), T. ukapirmasi n. sp., Archotermopsis tornquisti Rosen, Proelectrotermes berendtii (Pictet-Baraban), Electrotermes affinis (Hagen), E. girardi (Giebel), Reticulitermes antiquus (Germar), R. minimus Snyder, and Parastylotermes robustus (Rosen). Garmitermes succineus n. gen. n. sp. is the first Mastotermes-like termite discovered in Baltic amber. Hemerobites Germar, a senior synonym of Reticulitermes Holmgren, is designated as a nomen oblitum under the ICZN rules. Maresa Giebel, another senior synonym of Reticulitermes, is tentatively suppressed pending a petition to the ICZN to preserve the latter name.
Abstract: An unusual new lampyrid genus, Oculogryphus Jeng, Engel, and Yang, new genus, and its type species, Oculogryphus fulvus Jeng, new species, from Vietnam, is described and figured. The genus is characterized by its filiform antennae, large and ventrally approximate compound eyes that are deeply emarginate posteriorly, largely exposed head (i.e., not covered by the pronotum), eight abdominal ventrites, rectangular abdominal tergites, absence of photogenic organs, and symmetric aedeagal sheath and genitalia in the male (the female is presently unknown). The genus does not adequately fit into any subfamily as they are currently defined, highlighting the difficulties of the subfamilial and tribal classification presently in use. Though most likely allied to Ototretinae or Luciolinae, the systematic position of Oculogryphus cannot be determined as currently there is no comprehensive phylogeny of Lampyridae and related groups. The species may rely on photic cues for purposes of mating. A key to the genera of Lampyridae (sensu Crowson) occurring in Palaearctic East Asia, Oriental, and Australian regions is provided. Some taxonomic problems of Ototretinae are commented upon.
Abstract: New fossil termites (Isoptera) are described and figured from four Early Cretaceous deposits across Asia, including some of the oldest records for the order. In total seven new genera and six new species are established from these sites. A single, alate specimen is documented from the Zaza Formation (Berriasian) of Baissa, Transbaikalia (Siberia, Russia) and is described as Baissatermes lapideus n. gen. n. sp. Baissatermes lapideus n. gen. n. sp. is the oldest fossil termite presently known and the oldest known example of a social organism. Valditermes acutipennis Ponomarenko, from the Hauterivian of Mongolia, is transferred to a new genus, Khanitermes n. gen. (resulting in the new combination, Khanitermes acutipennis n. comb.). Melqartitermes myrrheus n. gen. n. sp. is described in Neocomian (Hauterivian) amber from Lebanon. The late Albian to early Cenomanian Burmese amber (Myanmar) harbors the greatest diversity of termites hitherto discovered from any Cretaceous amber locality. In total six species are documented in Burmese amber, including the following new taxa and combinations: Mylacrotermes cordatus n. gen. n. sp., Dharmatermes avernalis n. gen. n. sp., Proelectrotermes swinhoei (Cockerell) n. comb., P. holmgreni n. sp., Kachinitermes n. gen., Kachinitermes tristis (Cockerell) n. comb., Tanytermes anawrahtai n. gen. n. sp. The significance of these new taxa for understanding early termite evolution and basal relationships within Isoptera is discussed. A checklist of Cretaceous termites is provided.
Abstract: The bees (Apoidea: Anthophila) first diverged from the spheciform wasps sometime in the later part of the Early Cretaceous, about 125 million years ago. The sister group of the bees is probably the Crabronidae within the paraphyletic Sphecidae, which contains about 90% of the described spheciform diversity. The palaeoentomological data for sphecids are relatively poorly understood, but support the assumption of an early Cretaceous origin of the Apoidea (bees + sphecids). Cladistic, paleobotanical, and paleclimatological evidence suggests that the bees and sphecids originated in semi-arid regions of Gondwanaland and diversified from there. By the Late Cretaceous the major lineages had been established and these persisted into the Early Tertiary, with seemingly little affect from the K-T mass extinction event. The bees appear to have experienced more significant losses during the dramatic episode of global cooling marking the Eocene-Oligocene transition (one of the famed, "lesser" mass extinction events). Indeed, at this time several lineages of eusocial bees became extinct, leaving the four distinctive survivors of the corbiculate bees (i.e., honey bees, bumble bees, orchid bees, and stingless bees). Incorporating these "missing" tribes into phylogenetic studies supports the single origin hypothesis for eusocial and advanced eusocial behavior within this group of bees. During the Oligocene the bee and sphecid wasp fauna took on a relatively modern appearance and as such can be thought of as the epoch in which the modern bee fauna was born. Bees from the Oligocene and younger deposits provide evidence of localized extinctions (e.g., losses of several genera from the West Indian islands), recent episodes of diversification (e.g., speciation events among the honey bees), and other smaller-scale, evolutionary phenomena. ---------- Zusammenfassung: Bienen (Apoidea: Anthophila) entstanden irgendwann im späteren Verlauf der Unterkreide, also vor etwa 125 Millionen Jahren, aus Grabwespen-ähnlichen Vorfahren. Die Schwestergruppe der Bienen sind wahrscheinlich die Crabronidae innerhalb der paraphyletischen Sphecidae, die etwa 90% der bekannten Grabwespendiversität umfassen. Die paläoentomologischen Daten sind bei Grabwespen nunr unzureichend untersucht, unterstützen aber die Annahme eines unterkreideteitlichen Ursprungs der Apoidea (Bienen und Grabwespen). Kladistische, paläobotanische und paläoklimatologische Belege lassen vermuten, dass Bienen und Grabwespen in semi-ariden Gebieten Gondwanas und sich von hier aus diversifizierten. Bis zur Oberkreide hatten sich alle wesentlichen Linien etabliert und überdauerten bis in der frühe Tertiär, offenbar wenig beeinträchtigt durch das Massenaussterben an der K-T-Grenze. Stattdessen erlitten insbesondere die Bienen stärkere Verluste durch während der dramatischen Phase der globalen Abkühlung, die den Ãbergang vom Eozän zum Oligozän kennzeichnet (eine der bekannten, weniger signifikanten Massenextinktionen). In dieser Zeit starben eine Reihe von eusozialen Bienentaxa aus, und nur vier Gruppen eusozialer Bienen überlebten bis heute (die Honigbienen, die Hummeln, die Prachtbienen und die stachellosen Bienen). Phylogenetische Analyse der Beziehungen innerhalb der Bienen unter Einbeziehung der ausgestorbenen eusozialen Gruppen stützen die Annahme eines einmaligen Entstehens eusozialen und des höheren eusozialen Verhaltens innerhalb dieser Bienen. Während des Oligozäns nahm die Bienen- und Grabwespenfauna kontinuierlich moderne Gestalt an, und so kann diese Epoche als Geburtsstunde der moderne Bienen- und Grabwespenfaune angesehen werden. Bienen des Oligozäns und jüngerer Fossillagerstätten belegen lokale Extinktionen (z.B. der Verlust einiger Bienengattungen von den Westindischen Inseln), relativ rezente Diversifikationsereignisse (z.B. Speziationen bei Honigbienen) sowie anderer, weniger bedeutsamer Evolutionsereignisse.
Abstract: The geological history of the wasp superfamily Cynipoidea is reviewed, with the description of various new taxa mostly in Late Cretaceous amber from New Jersey and Canada. The various fossil lineages are incorporated into a phylogenetic analysis of the superfamily and their implications for understanding the evolution of the group explored. The following new taxa or taxonomic changes are proposed (authorship of all taxa Liu and Engel): Protimaspidae, new family; Stolamissidae, new family; Stolamissus, new genus; Stolamissus mirabilis, new species; Proliopterinae, new subfamily; Proliopteron, new genus; Proliopteron redactus, new species; Goeraniinae, new subfamily; Goerania, new genus; Goerania petiolata, new species; Micropresbyteria, new genus; Micropresbyteria caputipressa, new species; Anteucoila, new genus; Anteucoila delicia, new species; Jerseucoila, new genus; Jerseucoila plesiosoma, new species; Syneucoila, new genus; Syneucoila magnifica, new species; Tanaoknemus, new genus; Tanaoknemus ecarinatus, new species; Kinseycynips, new genus; Kinseycynips succinea (Kinsey), new combination. The extinct family Rasnicynipidae is newly transferred to Figitidae and classified as a basal subfamily therein (Rasnicynipinae, status novus). The Gerocynipidae, its type genus Gerocynips, and the type species upon which they are founded, Gerocynips zherichini, are found to be nomenclaturally unavailable. Gerocynips zherichini is regarded as a nomen nudum; the genus newly validated as Gerocynips, new genus (with G. siberica Kovalev as type species); the family validated as Gerocynipidae, new family. The fossil records of Cynipoidea are summarized.
Abstract: Three new species of the parasitoid wasp superfamily Mymarommatoidea (Proctotrupomorpha: Bipetiolarida) are described and figured in Cretaceous amber from New Jersey (Turonian) and Myanmar (Albian-Cenomanian boundary). The new taxa are Archaeromma carnifex Engel and Grimaldi, new species, in New Jersey amber, A. gibsoni Engel and Grimaldi, new species, in Burmese amber (both Mymarommatidae), and Galloromma kachinensis Engel and Grimaldi, new species, in Burmese amber (Gallorommatidae).
Abstract: The species of the firefly genus Vesta occurring in Taiwan are revised. Three species are recognized: Vesta scutellonigra Olivier (nomen emendatum), V. impressicollis Fairmaire, and V. rufiventris (Motschulsky). Vesta chevrolatii var. scutello nigro Olivier is automatically emended to scutellonigra under ICZN rules. Okada described as a distinct species V. scutellonigra, employing the same name and material as Olivier, thereby automatically rendering his taxon a junior synonym (n. syn.). The name V. scutellonigro, simultaneously employed by Okada, is considered an incorrect subsequent spelling and therefore unavailable. Vesta formosana Pic (n. syn.) is a new junior synonym of V. scutellonigra. The spelling chevrolati, employed by Gemminger and Harold, is determined to be an incorrect subsequent spelling of chevrolatii and thus unavailable. Lectotypes are newly designated for V. scutellonigra Olivier, V. impressicollis Fairmaire, and V. formosana Pic. A key to the species of Taiwan is provided. Vesta flaviventris (Fairmaire) (n. comb.) from China is transferred from Lucernuta.
Abstract: The purpose of this application, under Article 23.9.3 of the Code, is to conserve the usage of the genus-group name Reticulitermes Holmgren, 1913 (type species Termes flavipes Kollar, 1837) for an economically important and universally known group of termites, the subterranean termites responsible for most economic damage in the Northern Hemisphere. Two genus-group names have priority over Reticulitermes, both having been established for a common species of fossil termite in Baltic amber. Hemerobites Germar, 1813 (type species Hemerobites antiquus Germar, 1813) has not been used after 1899 and can be considered a nomen oblitum under Article 23.9.1 of the Code. Maresa Giebel, 1856 (type species Maresa plebeja Giebel, 1856) has been used once since 1899, in a large compendium on fossil insects, and, therefore, cannot be automatically considered a nomen oblitum. It is proposed that the genus-group name Reticulitermes be given precedence over Maresa.
Abstract: Family-group names for all taxa of earwigs (living and extinct) are listed with dates and sources indicated; in total 85 entries are recorded along with a single entry of dubious taxonomic identity (i.e., Ocelliidae, nomen dubium, a name apparently applied to a fossil earwig nymph of uncertain status and identity). This survey revealed two instances in which currently accepted names must be changed owing to priority by an older name â Platylabiinae and Cosmiellinae must be replaced by Palicinae and Skendylinae, respectively, as the family-group names remain valid despite synonymy of their type genera. The type genus of Verhoeffâs Gonolabididae (as Gonolabidae) is Gonolabis, not Gonolabina [which is the type genus of Gonolabininae (Gonolabiinae auctorum)] as asserted by various authors. In addition, the generally asserted authorship and dates of numerous names are found to be incorrect and are therefore revised herein. Most notably, the name Carcinophorinae as used by Hincks was a nomen nudum and therefore unavailable (the name was first made available by Popham). The widely employed spellings (all incorrectly formed) of Anataelinae, Challinae, Protolabinae, Anophthalmolabiinae, Titanolabinae, Gonolabinae, Brachylabinae, Isolabinae, Antisolabinae, Parisolabinae, Chaetospanini, Irdexinae, Eudohrninae, Rudraxinae, Gonolabinae, Rhyacolabinae, and Kinellinae are corrected to Anataeliinae, Challiinae, Protolabidinae (= Echinosomatinae), Anophthalmolabidinae, Titanolabidinae, Gonolabidinae (= Anisolabidinae), Brachylabidinae, Isolabidinae, Antisolabidinae, Parisolabidinae, Chaetospaniini, Irdicinae (= Spongophorinae), Eudohrniinae (= Neolobophorinae), Rudracinae, Gonolabininae, Rhyacolabidinae (= Ancistrogastrinae), and Kinesinae, respectively. The following nomenclatural changes are proposed: Acrania, reinstated as genus; Epicranopygia, new synonym of Acrania; Acrania angulata, new combination; A. constricta, new combination; A. eximia, reinstated combination; A. fletcheri, new combination; A. picta, reinstated combination; A. triangulata, new combination; A. vittipennis, new combination; Pyge, reinstated as genus; Paracranopygia, new synonym of Pyge; Pyge assamensis, new combination; P. bakeri, new combination; P. burmensis, new combination; P. comata, new combination; P. formosa, new combination; P. maculipes, new combination; P. meghalayana, new combination; P. modesta, reinstated combination; P. pallidipennis, new combination; P. proxima, new combination; P. semenovi, new combination; P. siamensis, new combination; P. similis, new combination; P. tonkinensis, new combination; P. variegata, new combination; P. vicina, new combination; Paradiplatys, reinstated as genus; Lobodiplatys, Heterodiplatys, and Epidiplatys, reduced to subgenera of Paradiplatys (and their included species reinstated in combination with Paradiplatys); Paradiplatys (Lobodiplatys) coriaceus, reinstated combination; P. (Paradiplatys) conradti, reinstated combination; P. (P.) lamottei, reinstated combination; P. (P.) pectinatus, reinstated combination; P. (P.) salvazae, reinstated combination; P. (P.) spinulosus, reinstated combination; P. (Heterodiplatys) bicolor, reinstated combination; P. (H.) bihamatus, reinstated combination; P. (H.) burri, reinstated combination; P. (H.) rotundicollis, reinstated combination; P. (H.) schoutedeni, reinstated combination; P. (Epidiplatys) gladiator, reinstated combination; Cretolabiinae, new subfamily (Anisolabididae); Paratitanolabis, new synonym of Titanolabis; Titanolabis bormansi, new combination; and Titanolabis myanmarensis, new name. ---------- Zusammenfassung: Die Namen aller Familiengruppen der Dermaptera (rezente wie ausgestorbene) werden einschlieÃlich der entsprechenden Quellen aufgelistet. Insgesamt konnten nicht weniger als 85 Namen ausfindig gemacht werden, einschlieÃlich eines Eintrags mit zweifelhafter taxonomischer Identität (Ocelliidae, nomen dubium, ein Name der anscheinend für eine fossile Nymphe mit unklarer Zugehörigkeit und Status verwendet wird). Diese Ãbersicht enthüllt zwei Fälle, in denen derzeit akzeptierte Namen aufgrund der Priorität anderer â Platylabiinae und Cosmiellinae durch Palicinae bzw. Skendylinae â ersetzt werden müssen, da die Namen der Familiengruppen, trotz der Synonymisierung der Typusgattungen, gültig bleiben. Die Typusgattung von Verhoeffs Gonolabididae (als Gonolabidae benannt) ist Gonolabis und nicht Gonolabina [die wiederum die Typusgattung für Gonolabininae (Gonolabiinae auctorum) ist], wie von einigen Autoren versichert wird. Darüberhinaus kann gezeigt werden, dass einige gebräuchliche Autorenschaften inkorrekt sind und dementsprechend hier revidiert werden. Vor allem trifft dies auf den Namen Carcinophorinae zu, der von Hincks eingeführt, sich als nomen nudum erweist und daher nicht verfügbar ist (er wurde zuerst von Popham verfügbar gemacht). Die häufig anzutreffenden, dennoch falsch abgeleiteten Schreibweisen von Anataelinae, Challinae, Protolabinae, Anophthalmolabiinae, Titanolabinae, Gonolabinae, Brachylabinae, Isolabinae, Antisolabinae, Parisolabinae, Chaetospanini, Irdexinae, Eudohrninae, Rudraxinae, Gonolabinae, Rhyacolabinae, und Kinellinae werden zu Anataeliinae, Challiinae, Protolabidinae (= Echinosomatinae), Anophthalmolabidinae, Titanolabidinae, Gonolabidinae (= Anisolabidinae), Brachylabidinae, Isolabidinae, Antisolabidinae, Parisolabidinae, Chaetospaniini, Irdicinae (= Spongophorinae), Eudohrniinae (= Neolobophorinae), Rudracinae, Gonolabininae, Rhyacolabidinae (= Ancistrogastrinae) bzw. Kinesinae berichtigt. Folgende nomenklatorischen Ãnderungen werden vorgeschlagen: Acrania, wiederhergestellt als Gattung; Epicranopygia, neues Synonym von Acrania; Acrania angulata, neue Kombination; A. constricta, neue Kombination; A. eximia, wieder hergestellte Kombination; A. fletcheri, neue Kombination; A. picta, wieder hergestellte Kombination; A. triangulata, neue Kombination; A. vittipennis, neue Kombination; Pyge, wiederhergestellt als Gattung; Paracranopygia, neues Synonym von Pyge; Pyge assamensis, neue Kombination; P. bakeri, neue Kombination; P. burmensis, neue Kombination; P. comata, neue Kombination; P. formosa, neue Kombination; P. maculipes, neue Kombination; P. meghalayana, neue Kombination; P. modesta, wieder hergestellte Kombination; P. pallidipennis, neue Kombination; P. proxima, neue Kombination; P. semenovi, neue Kombination; P. siamensis, neue Kombination; P. similis, neue Kombination; P. tonkinensis, neue Kombination; P. variegata, neue Kombination; P. vicina, neue Kombination; Paradiplatys, wiederhergestellt als Gattung; Lobodiplatys, Heterodiplatys, und Epidiplatys werden zu Untergattungen von Paradiplatys heruntergestuft und ihre Arten mit Paradiplatys kombiniert; Paradiplatys (Lobodiplatys) coriaceus, wieder hergestellte Kombination; P. (Paradiplatys) conradti, wieder hergestellte Kombination; P. (P.) lamottei, wieder hergestellte Kombination; P. (P.) pectinatus, wieder hergestellte Kombination; P. (P.) salvazae, wieder hergestellte Kombination P. (P.) spinulosus, wieder hergestellte Kombination; P. (Heterodiplatys) bicolor, wieder hergestellte Kombination; P. (H.) bihamatus, wieder hergestellte Kombination; P. (H.) burri, wieder hergestellte Kombination; P. (H.) rotundicollis, wieder hergestellte Kombination; P. (H.) schoutedeni, wieder hergestellte Kombination; P. (Epidiplatys) gladiator, wieder hergestellte Kombination; Cretolabiinae, neue Unterfamilie (Anisolabididae); Paratitanolabis, neues Synonym Titanolabis; Titanolabis bormansi, neue Kombination und Titanolabis myanmarensis, neuer Name.
Abstract: A lateral gynandromorph of Thyreus redactulus? Cockerell is described and figured, with a particular emphasis on the genitalic sclerites. As such, the sting morphology and mechanism are described for T. ramosus (Lepeletier de Saint Fargeau) so as to provide a comparative framework for understanding the gynandromorph. The implications of the gynandromorphâs genitalic arrangements for intersexual homologies are explored.
Abstract: The zorapteran fauna of Fiji is reviewed based on newly collected material from the âTerrestrial Arthropod Survey of Fijiâ. A single, endemic species, Zorotypus zimmermani Gurney, is recognized from Fiji, with new records from Vanua Levu and Taveuni. The alate has hitherto not been characterized and a description of the wing venation is accordingly provided for the species.
Abstract: A new bee species of the genus Amegilla (Apinae: Anthophorini) is described and figured from western Malaysia and southern Thailand. Amegilla anekawarna Engel, new species, belongs to the zonata group of species and can be most readily confused with the widespread A. zonata (Linnaeus). The species is distinguished from A. zonata and other Southeast Asian, blue-banded Amegilla.
Abstract: The genera of Cretaceous Scolebythidae are reviewed, with three new genera and species described from New Jersey (Turonian) and Lebanese (Barremian) amber. The new taxa are Boreobythus turonius, new genus and species, in New Jersey amber, and Zapenesia libanica, new genus and species, and Uliobythus terpsichore, new genus and species, in Lebanese amber. A cladistic analysis of living and fossil species of Scolebythidae is undertaken and a revised classification of the family proposed. Boreobythus is the oldest scolebythid in the New World, documenting the presence of the family in the Late Cretaceous of North America. The Eocene genus Eobythus is perhaps best considered a junior synonym of Pristapenesia but is tentatively retained herein. The historical biogeography of the family is briefly discussed. A key to the living and fossil genera of Scolebythidae is provided.
Abstract: A new species of the bee genus Ctenoplectra Kirby (Apinae: Euceriti: Ctenoplectrini) is described and figured from a series of males and females collected in central and northeastern Sulawesi (Indonesia). Ctenoplectra elsei sp. n. is most superficially similar to C. chalybea Smith (a largely mainland species with which many metallic blue species are confused) but differs in integumental sculpturing and structure of the terminalic sclerites, among other features. The species has been collected from Momordica cochinchinensis (Lour.) Spreng. (Cucurbitaceae: Cucurbitoideae: Joliffieae: Thladianthinae). The available information on nesting biology in Ctenoplectra is briefly reviewed along with flower visitation by Southeast Asian species.
Abstract: Two new species of augochlorine bees are described and figured from Ecuador. Caenaugochlora silvicola sp. n. is the first species of its genus with a relatively elongate malar space (although admittedly still shorter than true long-headed augochlorines) and can be readily distinguished from other Caenaugochlora by this trait as well as characters of coloration and integumental sculpturing. Caenaugochlora cuprina Moure & Hurd (= Augochlora cupriventris Friese), also from Ecuador, has proven to be a junior synonym of Megaloptilla callopis (Vachal) (syn. n.). Thus, C. silvicola sp. n. is the first true species of this genus formally documented from Ecuador. The second species does not correspond to any known group of augochlorines and is placed in a new genus herein. Rhynchochlora chlerogopsis gen. et sp. n. is most similar to Chlerogas but differs in head, antennal, and mesoscutellar structure.
Abstract: The first Chinese fossil of the family Nymphidae (Neuroptera: Myrmeleontiformia) is briefly described and figured along with two episomyline Osmylidae, a generally plesiomorphic group which can be easily confused with nymphids when only wings are known. Four new species and three new genera are characterized from Jurassic deposits of the Jiulongshan Formation (Daohugou Biota), Inner Mongolia, China. New genera are Liminympha (Nymphidae), Enodinympha (Osmylidae), and Nilionympha (Osmylidae), while the new species are Liminympha makarkini, Enodinympha translucida, Nilionympha pulchella, and N. imperfecta.
Abstract: Two new orchid bees of Euglossa subgenus Euglossella (Apinae: Euglossini) are described and figured from Peru. Both Euglossa (Euglossella) cosmodora sp. n. and E. (E.) urarina sp. n. belong to the decorata species group (i.e., the clade superficially resembling stingless bees of the genus Melipona) of Euglossella and are distinguished from their congeners as well as each other.
Abstract: Cenocephalus quasiexquisitus n.sp., is described and figured from the remains of a male preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. The new species is distinguished from C. exquisitus Bright & Poinar, also from Dominican amber.
Abstract: A new species of zorapteran (Polyneoptera: Zorotypidae: Zorotypus) is described and figured from alates and apterous individuals captured in Central Amazonia, Brazil. Zorotypus amazonensis Rafael and Engel, new species, is distinguished from related neotropical species by the setation of the male vertex, the peculiar development of the male cerci, female metafemoral ornamentation, female sternites, and presence of a true Cu vein in the hind wing base (permitting for the first time an accurate homologization of hind wing veins in Zoraptera). The Brazilian zorapteran fauna is briefly summarized and the homology and phylogenetic implications of cepahlic and wing venational traits discussed. The Embiodea + Zoraptera clade is dubbed mirorder Mystroptera Engel.
Abstract: Three new species of parasitoid wasp are described and figured from Early Miocene (Early Burdigalian) compression fossils from Rubielos de Mora Basin, Spain. These wasps are significant as they are representative of two families exceedingly rare in the fossil record. The first is a species of the family Perilampidae (Chalcidoidea) and, outside of an old and unconfirmed record of an undescribed Perilampus in Baltic amber, is the only documented fossil of this lineage. Perilampus renzii, new species, is described from a single female. The remaining two species are both of the family Megaspilidae (Ceraphronoidea), a family which is otherwise known in the fossil record solely from a paucity of species preserved in fossil resins. Conostigmus lazaros, new species, and C. chthonios, new species, are distinguished from each other as well as modern congeners.
Abstract: The fauna of fig wasps (Hymenoptera: Chalcidoidea: Agaonidae: Agaoninae) preserved in Early Miocene (Burdigalian) amber from the Dominican Republic is reported. Three species are described, representing both of the exclusively neotropical genera Tetrapus Mayr and Pegoscapus Cameron: Tetrapus delclosi Peñalver and Engel, new species, T. apopnus Peñalver and Engel, new species, and Pegoscapus peritus Peñalver and Engel, new species. All are described and figured based on females that are exquisitely preserved. The species are distinguished from each other as well as from modern relatives.
Abstract: A fourth species of rock crawler (Notoptera: Mantophasmatodea: Mantophasmatidae) is described and figured from an individual preserved in middle Eocene (Lutetian) Baltic amber. Adicophasma grylloblattoides Arillo and Engel, new species, is distinguished from its close relative, A. spinosum Engel and Grimaldi (reinstated), by the reduced pedicel, absence of spines on the maxillae, absence of mesofemoral spination, and proportions of the thoracic segments. The fossil shares with A. spinosum the presence of profemoral spination (confirmed by a new photograph of the holotype) and absence of the dorsal profemoral carina, characters that differentiate Adicophasma from the monotypic Raptophasma; it shares with all Baltic amber Notoptera the absence of the setal fan on the arolium. As noted by previous authors, the former order Mantophasmatodea is related to modern Grylloblattodea, whereas Mesozoic and Paleozoic grylloblattodeans represent a stem group to both. As such, Grylloblattodea and Mantophasmatodea are considered suborders of a single order, Notoptera Crampton (sensu novum), following the recommendation of Engel and Grimaldi (2004). The names for three rock crawlers are emended in order that the specific epithet may match the gender of the generic name: A. spinosum, Mantophasma zephyrum Zompro et al., and Tanzaniophasma subsolanum (Zompro et al.) (nomina emendata). Raptophasmatinae and Ensiferophasmatidae are new synonyms of Mantophasmatidae, while Tanzaniophasmatidae and Austrophasmatidae are newly demoted in rank to a subfamily and tribe of Mantophasmatidae, respectively. A hierarchical classification of Polyneoptera is appended.
Abstract: The first Mesozoic and currently oldest fossil of the wasp family Pompilidae (Aculeata: Euaculeata: Vespoidea) is described and figured from a female preserved in mid-Cretaceous (Albian) amber from Myanmar (Burma). Bryopompilus interfector, new genus and species, is distinguished from other fossil and living spider wasps and placed in the new tribe Bryopompilini. The sparse geological record of spider wasps is briefly reviewed and the current classification of the family outlined, with the spelling of three family-group names corrected â Cordyloscelidini, Eidopompilini, and Deuterageniini.
Abstract: The primitive silverfish Tricholepidion gertschi Wygodzinsky has traditionally been considered to be the sole surviving member of the family Lepidotrichidae, originally described from a middle Eocene fossil in Baltic amber. The fossil species, however, possesses apomorphic traits uniting it with more typical Zygentoma, and Lepidotrichidae in the traditional sense is grouped solely on plesiomorphic features. Tricholepidion is a relic of a more ancient diversification than Lepidotrichidae or even Lepidotrichidae + Euzygentoma (= Neozygentoma). Tricholepidion is therefore segregated into a separate family, Tricholepidiidae, familia novum, and Lepidotrichidae restricted to Lepidothrix in Baltic amber.
Abstract: A new genus of minute ammobatine bees is described and figured. Chiasmognathus gen. n. (Apidae: Nomadinae: Ammobatini) consists of three previously described species; Chiasmognathus gussakovskii (Popov) comb. n., C. orientanus (Warncke) comb. n. (with Pasites orientanus cyprius Warncke as a new synonym), and C. aegyptiacus (Warncke) comb. n.; as well as three or four additional species to be described in a forthcoming contribution. The genus occurs in eastern Europe, the Levant, and central, southwestern, and southern Asia. Chiasmognathus are cleptoparasites of species of Nomioides (Halictidae: Halictinae: Nomioidini).
Abstract: A new species of Osmia, subgenus Helicosmia, is described and figured from a male and female collected near Karaj, Iran. Osmia (Helicosmia) mediana sp. n. can be superficially confused with O. (H.) indigotea Morawitz and in other respects O. (H.) adae Bingham. The new species is diagnosed and distinguished from other Helicosmia.
Abstract: A new subgenus and species of Oxaea Klug (Andrenidae: Oxaeinae) is described and figured from western Ecuador. Oxaea (Alloxaea) brevipalpis subg. n. et sp. n., is noteworthy for the retention of maxillary palpi (3-segmented), absence of metallic integumental coloration, and contrasting notal pubescence. A preliminary key to the species of Oxaea, exclusive of the flavescens group, is provided as an aid to identification as well as a stimulus for future research on the genus. Mesoxaea and Notoxaea are reinstated as genera distinct from Protoxaea.
Abstract: A new species of the bee genus Tetralonia subgenus Thygatina is described and figured from southern India. Tetralonia (Thygatina) macroceps, new species, is particularly noteworthy for macrocephaly in males, among other characters. Previously the Oriental fauna of Thygatina was believed to consist of a single described species. Aside from T. (T.) fumida (Cockerell) and the new species proposed herein, the fauna also includes T. wickwari (Bingham), erroneously placed in Eucara (as a genus), and herein recognized as a species of Thygatina and is thereby also newly transferred to genus Tetralonia (new combination). In addition, there remains at least one additional, undescribed species but owing to confusion surrounding the association of sexes for T. fumida and T. wickwari this material is left unnamed. The need for additional collecting in southern India and Sri Lanka is stressed in order to resolve this difficulty. Lectotypes and paralectotypes are designated for T. fumida and T. wickwari.
Abstract: The remains of a new species of cuckoo wasp (Aculeata: Chrysidoidea: Chrysididae) are described and figured from a male preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Ceratochrysis dominicana sp. n. (Chrysidinae: Chrysidini) is the first chrysidid described in Dominican amber as well as the first fossil of the genus. The species is distinguished from modern congeners.
Abstract: Geratozygops atropos, new genus and species (Conoderinae: Zygopini), is described and figured from a single individual preserved in Early Miocene (Burdigalian) Dominican amber. Geratozygops atropos is the second documented fossil zygopine and the first in Dominican amber.
Abstract: The first known fossil species of Trypanaeus Eschscholtz (Histeridae: Trypanaeinae), Trypanaeus hispaniolus, new species, is described and figured from the remains of two females preserved in Early Miocene (Burdigalian) Dominican amber. The fossil history of Histeridae along with the higher-level classification of the subfamily Trypanaeinae is briefly discussed. An addition to the existing key to species of the genus is provided in order to accommodate the new, fossil species described herein.
Abstract: Two new species of dryophthorine weevils (Curculionoidea: Curculionidae: Dryophthorinae: Dryophthorini) are described and figured from remains preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Stenommatus pulvereus n. sp. and Dryophthorus acarophilus n. sp. are distinguished from each other as well as modern congeners. These are the first, described amber fossils of the subfamily Dryophthorinae and the fourth and fifth definitive fossil records for the Dryophthorini. Like many modern species of dryophthorines the fossils have been found in association with mites (Acari), indicating that this likely phoretic interaction is at least 19 million years old.
Abstract: Owing to their minute sizes, frail wings, and low abundances in entomological collections, zorapterans have been assumed to be highly endemic and poor dispersers. Wide distributions of some species are thought to be induced by human activity. Herein, we use the Genetic Algorithm for Rule-set Prediction (GARP) to model the potential distribution of Zorotypus hubbardi Caudell, one of 32 living species of the order Zoraptera. According to the model, the potential distribution of Z. hubbardi covers the southeastern U.S., with western limits in eastern Texas, eastern Oklahoma, and southeastern Kansas, and northern limits in southeastern Iowa in the West and southernmost New York in the East; the modelâs predictions exclude Z. hubbardi from the Appalachian Mountains. The northern and western boundaries of the potential distribution show that the ecological conditions for the natural occurrence of the species are present, and that the presence of colonies would not be solely dependent on coexistence with humans. New feral records from the areas shown in the potential distribution would establish the certainty of the model.
Abstract: A lectotype is designated for Oxaea flavescens Klug (1807), a widely encountered oxaeinae bee in South America and type species of the genus Oxaea (Anthophila: Andrenidae: Oxaeinae). The designation is done in order to fix and stabilize the application of the epithet.
Abstract: The remains of two new ensign wasps (Hypsisomata: Evanioidea: Evaniidae) are described and figured from individuals preserved in Cretaceous amber. Grimaldivania mckimorum sp. n. is described in Late Cretaceous (Turonian) amber from New Jersey. This is the second species of Grimaldivania and is distinguished from G. ackermani Basibuyuk, Fitton & Rasnitsyn by wing venation and structure of the antenna. Sorellevania deansi gen. et sp. n. is described in middle Cretaceous (latest Albian) amber from northern Myanmar (Burma). Sorellevania is the second genus of ensign wasps recognized from Burmese amber. The geological history of the Evanioidea is briefly reviewed, with the subfamily Hyptiogastritinae subf. n. (Evanioidea: Aulacidae) established.
Abstract: A new, extinct species of the wasp genus Lindenius (Crabroninae: Crabronini: Crabronina) is described and figured from two exquisitely-preserved specimens discovered in Early Miocene Dominican amber. Lindenius paleomystax, new species, represents the first record for the tribe Crabronini in Dominican amber and the southernmost record for the genus in the New World. The unique locality and habitat data begin to reveal a more complicated natural history for the genus than that suggested by Recent taxa alone. A checklist of fossil apoid wasps in amber is provided and the new species is discussed within the context of an overview of apoid wasp origins and evolution.
Abstract: The recently described giant fossil honey bee, Apis lithohermaea Engel, is introduced and briefly described. The species was recovered from middle Miocene deposits of Iki Island, Japan. Apis lithohermaea is the largest fossil honey bee discovered, rivaling in size the modern giant honey bee, A. dorsata Fabricius, and is the first recorded fossil of the dorsata species group. Although the dorsata group does not occur further north than Tibet and southern China and in the Philippines in the Pacific, this lineage occurred near what is today southern Korea and Japan during the Miocene. The geological history of the honey bees is briefly reviewed.
Abstract: A new species of raphidiid snakefly (Raphidioptera: Raphidiomorpha) is described and figured from the Eocene-Oligocene Florissant Formation of Colorado. Raphidia funerata, new species, is most similar to R. mortua Rohwer but can be distinguished by details of forewing venation.
Abstract: The fossil pelecinid Pelecinopteron tubuliforme Brues (Proctotrupoidea) is redescribed and figured based on a single, complete male preserved in middle Eocene (Lutetian) Baltic amber. Brues' original material is missing but comparison with his description and figures allows for positive identification of the species. Since the type material for this genus and species are untraceable and presumably destroyed the new specimen is herein designated as a neotype for the purpose of stabilizing the nomenclature and identity of this, the only definitive fossil of the family Pelecinidae.
Abstract: A new species of the neotropical bee genus Ischnomelissa (Halictinae: Augochlorini) is described and figured. Ischnomelissa rasmusseni, new species, is most similar to I. rhina but can be distinguished by the structure of the inner metatibial spur, coloration of the legs and metasoma, presence of strong tomentose bands on the metasoma, and other characters. A revised dichotomous key to the species of the genus is presented.
Abstract: The chalcidoid wasp family Leucospidae is recorded from the geological record for the first time. Leucospis glaesaria sp. n. is described and figured from a single female preserved in Early Miocene amber of the Dominican Republic. The species is distinguished from living Leucospis species and is placed nearest to the speifera group among New World taxa.
Abstract: The spittlebug species Clastoptera lawsoni Doering is redescribed from specimens collected in Arizona that were compared with the type series and others determined by Doering. This species is frequently parasitized by the drosophilid fly Cladochaeta johnsonae Nguyen (Diptera: Drosophilidae).
Abstract: Three new species of the endemic West Indian bee lineage Habralictellus are described. Habralictellus rufopanticis sp. nov. occurs on Puerto Rico, Mona Island and the British Virgin Islands while H. eickwortellus sp. nov. is known only from Puerto Rico. Habralictellus eleutherensis sp. nov. is described from the Bahamas and Cuba. Available floral records for H. rufopanticis are provided.
Abstract: The oldest fossil bee, "Trigona" prisca (Apidae: Meliponini), in Late Cretaceous (Maastrichtian) amber from New Jersey, is redescribed and figured. Differences between T. prisca and extant Trigona are noted and the fossil is transferred into a new genus, Cretotrigona. An exploratory cladistic analysis of the Meliponini is undertaken and Cretotrigona supported as sister to the African genus Dactylurina. Affinities between Cretotrigona and recent genera are discussed as are implications of the presence of this derived stingless bee group at the end of the Mesozoic.
Abstract: The first fossil Euglossa (tribe Euglossini) is described and figured from Miocene Dominican amber as Euglossa moronei new species. The species is differentiated from extant euglossines, and its apparent lack of close affinity to any extant subgenus or species group is discussed. The existing data pertinent to the internal phylogeny of Euglossini are reconsidered, and a new hypothesis of relationships among the genera is proposed. The distribution of the euglossines, particularly in the West Indies, and their associations with orchids is briefly considered.
Abstract: A bee of the family Megachilidae is recorded as an amber inclusion for the first time. The individuals is representative of a primitive new subgenus and species of the genus Megachile, Chalicodoma subgeneric complex. Megachile glaesaria, new species, is described and figured from a single female preserved in Miocene Dominican amber. The subgenus Chalicodomopsis, new subgenus, is proposed for this taxon. The fossil appears most similar to species of the subgenus Chelostomoides and, in particular, the recent M. manni Mitchell, an exceedingly uncommon species presently known only from southern Arizona. The known fossil Megachilidae are briefly reviewed (none are older than the Eocene-Oligocene) and recent debates on early megachilid nest evolution considered.
Abstract: A new species of inocelliid snake-fly, Fibla carpenteri, is described and figured from middle to Upper Eocene Baltic amber. The species belongs to the nominate subgenus and is the largest amber snake-fly currently known. The aberrant fossil species Inocellia peculiaris is transferred to a new genus, Electrinocellia, and placed in a new subfamily, the Electrinocelliinae, sister to the remainder of the Inocelliidae.
Abstract: Twenty-nine colonies of a population of the cooperative spider Stegodyphus sarasinorum Karsch (Eresidae), from two sites in Bangalore, Karnataka State, India, were examined using protein allozyme electrophoresis. Thirty-five enzyme systems were examined. Twenty-two enzymes (the products of 25 putative loci) gave scorable results. Lactate dehydrogenase (LDH) and glucose-6-phophate dehydrogenase (G6PDH) were polymorphic with two alleles each; hexokinase exhibited uninterpretable variation. The rest were monomorphic. One LDH allele was found at only one of two collection sites, and one G6PDH allele was found only at the other collection site. The pattern of variation in S. sarasinorum is similar to that found in three other studies of cooperative spiders: extreme population subdivision, with most colonies consisting of identical homozygotes.
Abstract: Males of solitary bees usually spend the night in clusters on small branches of plants, cavities and flowers. The individuals usually return to the same location each evening during their life, exhibiting site fidelity to a particular plant. The present paper reports the sleeping roosts of the males of some oil-collecting bees of the genera Centris, Paratetrapedia, Lanthanomelissa, Monoeca and Tetrapedia.
