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.

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.

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.

Fossil Specimen

A new genus and species, Mirimordella gracilicruralis gen. et sp. nov., in the subfamily Praemordellinae of Mordellidae, is described and illustrated based on a nearly complete fossil specimen. It is from the Yixian Formation of western Liaoning Province, NE China. The diagnosis of the subfamily Praemordellinae is emended based on this new species. Characters such as simple and linear maxillary palpi, simple claws, simple penultimate segments of fore and middle tarsi, small hind coxal plates, slender hind femora, only apical ridges on hind tibiae and tarsi, and no elongated last tergum suggest that Praemordellinae might be the precursor of modern mordellids. The resemblance between the new species and the Late Jurassic Praemordella martynovi indicates close relationships between them and with the tribe Stenaliini in the subfamily Mordellinae. The position of epicoxa and slender hind femur suggest that the new species may be more primitive than Praemordella martynovi and may indicate the age of the Yixian Formation no later than Late Jurassic.

In this paper a new species Cretonanophyes zherikhini sp. nov. and a new genus and species Abrocar brachyorhinos gen. et sp. nov., all placed within the family Eccoptarthridae, are described and illustrated. They pertain to the Late Jurassic Yixian Formation of the western Liaoning province, China. This finding represents the first record of fossil eccoptarthrids from China.

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.

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

Two New Species

The early Miocene site of Wadi Moghra, Qattara Depression, Egypt, is important for interpreting anthracothere (Mammalia, Artiodactyla) evolution, because the Moghra sediments preserve a higher diversity of anthracotheres than any other pene-contemporaneous site. New specimens from Moghra are described and form the basis for the systematic revision of Moghra anthracotheres provided here. Among the important discoveries recently made at Moghra is the first complete skull of Sivameryx moneyi. Other new specimens described here include two new species of Afromeryx, and a new genus and species, all of which are unique to Moghra. A review of biogeographic information supports the conclusion that three of the Moghra anthracotheres (Brachyodus depereti, B. mogharensis, and Jaggermeryx naida, n. gen. n. sp.) are members of late surviving lineages with a long history in Africa, while three other species (Afromeryx grex, n. sp., A. palustris, n. sp., and Sivameryx moneyi) represent more recent immigrants from Eurasia.
