Abstract: A new stem-orthopteran insect assignable to theâtraditionalâgenus and theâ
cladotypic-definedâtaxon Miamia Dana, 1864 is described based on abundant material
collected from the Xiaheyan locality (Ningxia, China; Early Pennsylvanian). Intra-specific
wing venation variability in Miamia maimai n. sp. is appreciated based on wing pairs of
single individuals, and on a complete series of conditions. Rare variants are reported.
Details of head and leg morphology are documented: the new species possesses a five
Abstract: Liassophyllum caii Gu & Ren sp. nov., the first Middle Jurassic (BathonianâCallovian
boundary interval) Cyrtophyllitinae species is described from the Jiulongshan Formation of
Daohugou, Inner Mongolia, China. The exceptionally well-preserved materials reveal fine
details of the body structure and morphology including extremely long antennae, the
positions of antennal sockets, elongate cerci, long saltatory legs and forewing variations.
Abstract: Abstract During the Upper Carboniferous, orthopteran insects (grasshoppers, katydids, and
crickets) were represented by numerous species distantly related to crown-orthopterans,
such as lobeattid and cnemidolestodean insects. The panorthopterans, including total-
orthopterans and their closest relatives, are represented by comparatively rarer species in
localities of this period. Here we describe Heterologus duyiwuer sp. nov., an infrequent
panorthopteran from the Late Carboniferous locality of Xiaheyan Village (Zhongwei City
Abstract: Behaviors are challenging to reconstruct for extinct species, particularly
the nature and origins of acoustic communication. Here we
unravel the song of Archaboilus musicus Gu, Engel and Ren sp. nov.,
a 165 million year old stridulating katydid. From the exceptionally
preservedmorphology of its stridulatory apparatus in the forewings
and phylogenetic comparison with extant species, we reveal that A.
musicus radiated pure-tone (musical) songs using a resonant mechanismtuned
at a frequency of 6.4 kHz. Contrary to previous scenarios,
musical songs were an early innovation, preceding the broad-bandwidth
songs of extant katydids. Providing an accurate insight into
paleoacoustic ecology, the low-frequencymusical song of A. musicus
was well-adapted to communication in the lightly cluttered environment
of the mid-Jurassic forest produced by coniferous trees and
giant ferns, suggesting that reptilian, amphibian, and mammalian
insectivores could have also heard A. musicusâ song.
Abstract: Abstract Longzhua loculata n. gen. n. sp., a new Pennsylvanian Archaeorthoptera (ie, stem-
Orthoptera), is described from the Tupo Formation based on 64 specimens, including an
individual with parts of body and legs preserved. The range of intra-specific variation in
forewing venation pattern is documented in detail. Well-preserved isolated hind wings are
associated with forewings based on more complete material. The combination of character
states exhibited by the new species indicates relationships with the extinct order
Abstract: Abstract Taxonomy is investigated and revised for some prophalangopsid insects, yielded
by the Middle Jurassic Jiulongshan and Upper Jurassic-Lower Cretaceous Yixian
formations in China. Flexaboilus retinervius Li, Ren & Meng, 2007 and Furcaboilus excelsus
Li, Ren & Meng, 2007 are considered as synonyms of Allaboilus gigantus Ren & Meng,
2006. Protaboilus lini Ren & Meng, 2006 is considered a synonym of Aboilus stratosus Li,
Ren & Wang, 2007. Hebeihagla Hong, 1982b, Habrohagla Ren, Lu, Guo & Ji, 1995
