Four extinct new species referable, respectively, to three extinct new genera within Trichoceridae have been recovered from the Jurassic Daohugou Formation in Ningcheng, Chifeng, Inner Mongolia, China: Archaeotrichocera ephemera gen. et sp. nov., Tanyochoreta integera gen. et sp. nov., Tanyochoreta chifengica sp. nov., and Sinotrichocera parva gen. et sp. nov. The specimen described earlier as trichocerids from China, Mesotrichocera laiyangensis Hong and Wang 1990, does not belong to this family. The Daohugou biota comprises a wide range of vertebrate and invertebrate organisms that inhabited, a small lake, luxurious everglade, streams, and forest with volcanoes nearby. The Daohugou Formation can be compared to the Karabastau and Haifanggou formations based on biostratigraphic correlation. The geological age for trichocerid-bearing nonmarine volcano-sedimentary rocks may be latest Middle Jurassic (Callovian) or earliest Late Jurassic (Oxfordian) rather than early–middle Middle Jurassic or Early Cretaceous.

Two new genera and new species, Peregrinpachymeridium comitcola gen. et sp. nov. and Corollpachymeridium heteroneurus gen. et sp. nov., of fossil Pachymeridiidae are described and illustrated from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia Autonomous Region, China. We summarized all fossil genera of pachymeridiids found in China and set up a key to these 7 genera and 7 species. In addition, we hypothesize the significance of a rare, well-preserved, unusual bug fossil showing a male and a female together with their abdomen terminalia facing each other and their heads in the opposite direction.

Two new genera and two new species of fossil rhopalid, Miracorizus punctatus gen. & sp. nov. and Longiclavula calvata gen. & sp. nov., are described and illustrated. They were collected from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. This is the earliest fossil record of the family Rhopalidae in the world.

In this paper two new genera and three new species of Palaeontinidae are described: Quadraticossus gen.nov., containing two new species, Q. fangi and Q. longicaulis; Hamicossus laevis gen. et sp. nov. These two new genera are established based on both complete forewings and hind wings. All of them were collected from the Middle Jurassic Jiulongshan Formation at Daohugou Village, Inner Mongolia. The type specimens are deposited in the College of Life Science, Capital Normal University.

Three New Species

Two new genera and three new species of family Taeniopterygidae, Jurataenionema inornatus Liu and Ren, gen. et sp. nov., Jurataenionema stigmaeus Liu and Ren, gen. et sp. nov. and Protaenionema fuscalatus Liu and Shih, gen. et sp. nov. are described from Daohugou village (Middle Jurassic), Inner Mongolia, China. These are the oldest records of Taeniopterygidae. The venations of these two genera were very simple, providing evidence that the costal crossveins and the occasional apical crossveins are derived characters. We suggest the same is true of the extra branches of Rs and CuA in family Taeniopterygidae. Extra branches and crossveins added through geologic time might have improved aerodynamics of the wings.

Two new genera with two new species, Formosibittacus macularis gen. et sp. nov. and Jurahylobittacus astictus gen. et sp. nov. are described on the basis of well preserved specimens collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. Formosibittacus can be distinguished from all known genera by a combination of the following features: three cross-veins between R 1 and R 2+3 ; one pterostigmal cross-vein; and two cross-veins between M 4 and CuA. Jurahylobittacus differs from all known genera by a combination the following of characters: one cross-vein between R 1 and R 2+3 ; one pterostigmal cross-vein; and two cross-veins between M 4 and CuA.

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 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.

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 Species

A new species of the family Grammolingiidae (Neuroptera) (Leptolingia imminuta sp. nov.) is described from Daohugou village (Middle Jurassic), Inner Mongolia, China. In this new species, MA forks at the same level as the separation of Rs2 from Rs, close to the middle of forewing, this structure of MA is peculiar in Grammolingiidae and is different from that of all other known species. Moreover, this new species is the smallest species known in the family Grammolingiidae (30 mm wing span).
