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

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 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.

A New Species

A new species Karatawia sinica Li, Nel et Ren, sp. nov. is described from the Middle Jurassic Jiulongshan Formation, and compared with the other species of this genus. As it is based on a new fossil with fore- and hindwings preserved, it confirms the attribution of Karatawia sibirica to this genus, of Karatawia to the Campterophlebiidae, and the synonymy of the Karatawiidae with this family. Otherwise, the two other species K. mongolica and K. shurabica, which are based on more incomplete specimens, are more properly to be considered as Campterophlebiidae incertae sedis.

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

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.

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.

A new species of Cyrtophyllitinae, Archaboilus polyneurussp. nov. Gu, Yue & Ren, is described from the Middle Jurassic Jiulongshan Formation, Daohugou Village, Inner Mongolia, China. The species is characterized by its ScA reaching the anterior wing margin at the level of the divergence of M+ CuA, distally branched RP, lengths of free CuA and free M equal, and numerous branches of CuA + CuPaα. A new fossil of Liassophyllum caii Gu & Ren, 2012 is described which increases knowledge of its wing venation and indicates that Liassophyllum should be assigned to the Tuphellidae.

In this paper a complete specimen of fossil Palaeontinidae, Suljuktocossus yinae sp. nov. from Daohugou (Jiulongshan Formation) in Inner Mongolia, China is described. This new species is established based on both complete forewings and hindwings. According to this specimen, the diagnosis of the genus Suljuktocossus is revised. Moreover, based on the distribution of the genus Suljuktocossus, we consider the age of the Daohugou biota as Middle Jurassic
