Abrotoxyela gen. nov. of Xyelidae and Abrotoxyela lepida sp. nov. and Abrotoxyela multiciliata sp. nov. are described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. The new genus is established on basis of the triple-branched vein Sc of the fore wing with first branch intersecting C at nearly 1/4 of its length; Sc terminates at C distal to the origin of Rs; and basal section of Rs approximately as long as that of M.

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.

The new aeshnopteran genus and species Sinocymatophlebiella hasticercus is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia. It shows important similarities with the Jurassic genus Cymatophlebiella from Karatau, suggesting they could belong to the same family, but the latter genus is too poorly known to accurately establish its affinities. The present discovery supports the evolutionary scenario of a Jurassic rapid and massive diversification of the Aeshnoptera, followed by important extinctions during the Late Mesozoic.

Platyxyela unica, gen. et sp. nov., assigned to the Macroxyelinae of Xyelidae is described from the Middle Jurassic Jiulongshan Formation of eastern Inner Mongolia, China. The new genus is characterized by Sc2 of the forewing meeting R at a short distance before the origin of Rs, the first section of Rs being shorter than the first section of M and nearly equal to Sc2, the antennomere 3 being shorter than the combined length of the remaining flagellomeres, the ovipositor sheath being much longer than wide. An updated key for the known genera of Macroxyelinae is given.

AbstractA new rove beetle, Sinanthobium daohugouense, new genus, new species, is described and illustrated on the basis of a tiny impression fossil from the Middle Jurassic Jiulongshan Formation at Daohugou, Inner Mongolia, China. The new genus is placed in the subfamily Omaliinae (Coleoptera: Staphylinidae), tentatively in the Recent tribe Anthophagini. The first find of a definitive omaliine beetle from the Middle Jurassic of China provides direct evidence on the origin and early evolution of Omaliinae.

AbstractA new genus and species, Aclemus patulus n. gen. n. sp., is described based on a new specimen collected from the latest Middle Jurassic Jiulongshan Formation in Inner Mongolia, China. Based on a combination of characters from this fossil, including a homonomous fore- and hindwing, a 3-branched media vein, wings lacking long cilia on their margins; and a cross-vein absent between subcosta and radius, we establish a new genus assigned to the Eolepidopterigidae. In addition, the diagnosis of Longcapitalis excelsus Zhang, Shih, Labandeira and Ren 2013, is emended based on new fossil material.

Mirivena robusta gen. & sp. nov., a fossil plant bug, is described from the Jiulongshan Formation (Middle Jurassic) in Daohugou Village, Shantou Town, Ningcheng County, Inner Mongolia, China. The remarkable features of the new species are the large body size and the R vein reaching the anterior margin of the fore wing. This mirid represents the oldest fossil plant bug so far known.

This is the earliest fossil record of buprestids in China and it is also the first record of buprestids from the Middle Jurassic Jiulongshan Formation of China.

A new genus and species of rhagionids with a long proboscis, Elliprhagio macrosiphonius gen. et sp. nov., is described from the Middle Jurassic Jiulongshan Formation in Daohugou, Inner Mongolia, China, which is considered to be the earliest hematophagous rhagionid described hitherto according to the typically piercing and sucking mouthparts. All previously documented rhagionids from northeastern China are reviewed a key to genera of Rhagionidae from Daohugou is provided for the first time. The genus Daohugorhagio Zhang, 2013 is considered as a new synonym of Trichorhagio Zhang, 2013.

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.
