Revision of “Parahagla lamina” Lin, 1982 and two new species of Aboilus (Orthoptera: Prophalangopsidae) from the EarlyMiddle Jurassic of Northwest China

The Lower and Middle Jurassic insects are rather poorly known from Northwest China. Here we restudy Parahagla lamina Lin, 1982 and transfer it from “Parahagla” to Aboilus Martynov, 1925. On the basis of the female forewing, we described two new species of the EarlyMiddle Jurassic, Aboilus tuzigouensis sp. nov. caome from Badaowan Foramtion at Tuzigou, Kelamayi, Xinjiang, Northwest China and A. jiyuanensis sp. nov. from Ma’ao Group, Jiyuan, Henan Province, Central China. The differences of the new materials from the other known species and their systematic positions are also discussed.
