A New Species

The poorly known genus Nilionympha Ren and Engel, 2007 in the subfamily of Gumillinae is updated and revised based on the reexamination of the type specimens and description of a new species Nilionympha shantouensis sp. nov. from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. A further comparison between Nilionympha and other gumilline genera is provided to corroborate the generic status according to the updated diagnostic characters of forewing. The species Nilionympha imperfecta Ren and Engel, 2007 is transferred to the genus of Enodinympha.

ABSTRACTThe genus Orthobittacus was established by Willmann (1989) and is characterised by a long Sc vein and the unusually developed medial sector for the Bittacidae. Four Jurassic species have been described in this genus to date: O. abshiricus (Martynova, 1951) from Kirgizia; O.desacuminatus (Bode, 1953) from Braunschweig (Germany); O. polymitus Novokshonov, 1996 from Karatau (Kazakhstan); and O. maculosus Liu, Shih, Bashkuev & Ren, 2016 from the Jiulongshan Formation of Daohugou (China). The fifth congeneric and second species from China, O. suni sp. nov., is described herein. The importance of the genus Orthobittacus for the phylogeny of Bittacidae, as the most plesiomorphic genus, is discussed.

A New Species

A new species of Ripiphoridae Gemminger & Harold, 1870, Archaeoripiphorus nuwa gen. et sp. nov., is described and illustrated from a well-preserved impression fossil from the Middle Jurassic Jiulongshan Formation collected at Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, representing the oldest documented occurrence of the Ripiphoridae described from the Mesozoic era. It shares several characters belonging to two basal ripiphorid subfamilies (Pelecotominae and Ptilophorinae), but it cannot be attributed to either of them and is herein placed as Subfamily incertae sedis. An overall similarity between Archaeoripiphorus gen. nov. and Recent Pelecotominae and the occurrence of wood-boring beetles in the same Formation implies a similar parasitoid host preference in xylophagous beetles for A. nuwa gen. et sp. nov., putting a spotlight on a potential host-parasitoid relationship in the Mesozoic.

A New Species

A new genus with a new species (Jurachresmoda gaskelli gen. et sp. nov.) of Chresmodidae (Insecta: Polyneoptera: Orthopterida) is described and illustrated. They were collected from the Middle Jurassic in Daohugou, Jiulongshan Formation, Inner Mongolia (Nei Mongol Autonomous Region), China. J. gaskelli have fringing hairs on tarsi and a part of tibiae of mid legs. These hairs and leg structures were probably associated with its water-skiing locomotion on freshwater. A high number of tarsomeres, e. g. ultra-articulated tarsi as reported in other species of Chresmodidae, are also found for this new species. But, these true tarsi are mixed with some wrinkles resulted from dehydration and compression during fossilization process. Nymphs of the new species are also described. This is the first time that long and segmented cerci of the nymph are described in Chresmodidae.

Yumenia Hong, 1982 preoccupied by Yumenia Hou, 1958, is replaced with Gansucossus (Hemiptera, Palaeontinidae). The diagnostic characters for Gansucossus are presented and synonymies for Gansucossus pectinatus (Hong, 1982) and Gansucossus luanpingensis (Hong, 1983) are established. The diagnostic characters for G. pectinatus and G. luanpingensis are revised. A new species, Gansucossus typicus sp. nov., is described from the Middle Jurassic of Daohugou, Inner Mongolia, China. The new genus Daohugoucossus gen. nov. and new species Daohugoucossus solutus sp. nov., are erected based on a hind wing from the Middle Jurassic of Daohugou.

A new species of Prophalangopsidae, Bacharboilus lii sp. nov., is described. It was collected from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Ningcheng County, Chifeng City, Inner Mongolia, China. This exquisitely preserved specimen exhibits clear wing venation and head structures, especially the mouthpart morphology. The stout mandibles bear well defined molar dentes which indicate an herbivorous feeding habit.

A New Species

The diagnostic characters for Sinopalaeocossus Hong, 1983, belonging to the Palaeontinidae Handlirsch, 1906, are revised. This genus is remarkably different from others in the fore wing, whose branches of Sc are obscure and antenodal region is square; and in the hind wing, whose M 3+4 is unbranched and arises from stem M, whose M 1+2 fork is more distal and A 1 is absent. A new species, Sinopalaeocossus trinervus sp. nov., is described based on two well preserved specimens from the Middle Jurassic of Daohugou, Inner Mongolia, China; this is the first palaeontinid specimen with complete fore and hind wings articulated.

A New Species

Contrary to the typical southern distribution of the extant Kempyninae, a subfamily of Osmylidae, its fossil group shows the high diversification in the northern hemisphere during the Mesozoic. Herein a new genus with a new species, Mirokempynus profundobifurcus gen. et sp. nov., and a new species, Jurakempynus loculosus sp. nov., of Kempyninae, are described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. The new species share the characteristic synapomorphies of Kempyninae, e.g. subcostal veinlets mostly irregularly forked in the forewing and the distinctly expanded intramedial area with multiple rows of cells in the hind wing. The new genus distinctly shows a particular condition of intramedial area and MP branching in the hind wing. However, the condition of the region between MA and MP significantly broadened in the hind wing appear distinctively different to other known kempynine genera. A key is provided for all the genera of documented kempynines, both fossil and extant.

A New Species

A new genus with a new species, Fuscopolystoechotes reticulatus Xu, Zheng, Shih & Wang, gen. et sp. nov., and a new species Lichenipolystoechotes fenestratus Xu, Fang, Shih & Wang, sp. nov. of Ithonidae, are described from the Middle Jurassic Jiulongshan Formation, Inner Mongolia, China. Both new species are assigned to Polystoechotes genus-group mainly based on the combination of following characters: the distinctly narrowed costal space in distal half, presence of recurrent humeral veinlet and ScA, absence of interlinked crossveins in between costal crossveins, converged ScP and RA and pectinately branched MA and MP in distal. But the new genus of Fuscopolystoechotes gen. nov. is differentiated from all other genera by a combination of characters, i.e., specialized markings on forewing; scp-ra crossveins absent; CuP with pectinate branches and crossveins in RP–A area complicated. These two new species with the remarkable markings in forewings are considered to be adapted for the particular Mesozoic environments for camouflage or mimicry.
