A new genus and two new species of extinct Mesochrysopidae (Neuroptera) are described from the Mesozoic of China:Protoaristenymphes daohugouensis sp. nov., from the Middle Jurassic of Daohugou, Inner Mongolia; and Kareninoideslii gen. et sp. nov., from the Early Cretaceous (Yixian Formation) of Dakangpu, Liaoning Province. The presence of CuPin one hind wing of K. lii gen. et sp. nov. is interpreted as an atavism. Armandochrysopa Nel et al. is regarded as a newjunior synonym of Karenina Martins-Neto. Armandochrysopa inexpecta Nel et al. is tentatively transferred to Kareninoides gen. nov.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

A new genus and two new species of fossil Elateridae are described and illustrated: Paralithomerus gen. nov., P. exquisitus sp. nov, and P. parallelus sp. nov. Both species were collected from the Late Jurassic-Early Cretaceous Yixian Formation of western Liaoning, China. Fossil elaterids expressing a sutured mesoventrite have been otherwise discovered only from the Upper Jurassic strata of Karatau.

Hybosoridae is a relatively small family of Scarabaeoidea, including five extant and one fossil subfamily (Ocampo & Ballerio 2006, Nikolajev 2007). Until now, 20 fossil species were known from five subfamilies: Anaidinae, Ceratocanthinae, Hybosorinae, Liparochrinae, and Mimaphodiinae (Ocampo & Ballerio 2006, Krell 2007, Nikolajev 2008, Nikolajev et al. 2010, Nikolajev 2010a, Nikolajev 2010b, Kirejtshuk et al. 2011). In this paper we describe Pulcherhybosorus tridentatus Yan, Bai, & Ren new genus and new species, from a nearly complete and well-preserved fossil. This fossil represents the first record of Hybosoridae from the Early Cretaceous Yixian Formation of Liutiaogou, Inner Mongolia in China. This significant finding tentatively confirms the presence of Hybosoridae during the Mesozoic in what is now China.

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 genus and two new species of Xyelidae Newman, 1834 (Hymenoptera Linnaeus, 1758), Platyxyela tenuis sp. nov. and Scleroxyela daohugouensis gen. et sp. nov. are described and illustrated from the Middle Jurassic Daohugou Beds of Ningcheng, Inner Mongolia, China. Platyxyela tenuis sp. nov. (Xyelinae Newman, 1834, Liadoxyelini Rasnitsyn, 1966) can be distinguished from its congeners by short forewing length and ovipositor sheath strongly narrowed toward acute apex. Scleroxyela daohugouensis gen. et sp. nov. is placed within Macroxyelinae Ashmead, 1898, Xyeleciini Benson, 1945 based on pterositigma completely sclerotised and costal space sclerotised before ptrostigma, 1-Rs half as long as 1-M, and 1m-cu short. It is the first recorded species of Xyeleciini in Daohugou Beds. Furthermore, an updated key of identification of subfamilies and tribes of Xyelidae is provided. Our findings of new morphological data provide insights into the early evolution of Hymenoptera, as well as effectively enrich our understanding of the diversity of Xyelidae in the Mesozoic.

A new genus and two new species of the extinct family Hexagenitidae, Epicharmeropsis hexavenulosus gen. et sp. nov. and Epicharmeropsis quadrivenulosus sp. nov., are described from the Late Jurassic-Early Cretaceous Yixian Formation, Hebei and Liaoning Provinces in China. Detailed description and illustration of the specimens along with a brief review of Hexagenitidae are given. By comparing with the imago specimens of so-called Ephemeropsis which were previously reported from China, we believe these Ephemeropsis-like specimens should be placed into Epicharmeropsis gen. nov. and Ephemeropsis Eichwald could be absent in China.

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 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.

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

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.
