Two new species of Diptera, Eoptychopterina postica sp. nov. in Ptychopteridae and Eotrichocera (Archaeotrichocera) spatiosa sp. nov. in Trichoceridae are described and illustrated from the Middle Jurassic Jiulongshan Formation of Daohugou in eastern Inner Mongolia, China. These two new species are established based on fossil specimens with bodies and complete wings.

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.

Two new species,Symphytopterus gracilersp. nov. of the family Ephialtitidae andPraeaulacus byssinussp. nov. of the family Praeaulacidae, are described and illustrated from the late Middle Jurassic of Jiulongshan Formation at Daohugou in Inner Mongolia, China. Based on new information onS. gracilersp. nov. andP. byssinussp. nov., two taxonomic keys to the known species of generaSymphytopterusandPraeaulacusare provided. By comparing the wings ofSymphytopterus, we find that the change of the veins length is the main interspecific difference andS. liasinusmay occupy the most basal position inSymphytopterus.

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.

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.
