摘要

A new species of Prophalangopsidae, Bacharboilus lii sp. nov., is described. It was collected from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Ningcheng County, Chifeng City, Inner Mongolia, China. This exquisitely preserved specimen exhibits clear wing venation and head structures, especially the mouthpart morphology. The stout mandibles bear well defined molar dentes which indicate an herbivorous feeding habit.
