A new genus of Chifengiinae (Orthoptera: Ensifera: Prophalangopsidae) from the Middle Jurassic (Jiulongshan Formation) of Inner Mongolia, China

The Middle Jurassic Ashangopsis daohugouensis, gen. et sp. n., of the prophalangopsid subfamily Chifengiinae is described based on two well-preserved specimens collected from the fossil locality near Daohugou at Ningcheng County, Inner Mongolia, Northeast China. The new genus is characterized by the particular shape of its pronotum, its hind leg, and stridulatory veins that only concern the cubital area but not the anal area, unlike in other Chifengiinae.

RésuméLe Prophalangopsidae : Chifengiinae Ashangopsis beigouensis, gen. et sp. n., est établi à partir de deux spécimens bien préservés du Jurassique moyen de Daohugou, Ningcheng County, Chine. Il est caractérisé par un appareil stridulatoire très particulier, qui n’implique que des nervures du champ cubital et non du champ anal, contrairement au cas des autres Chifengiinae.
