A new species of the family Prophalangopsidae, Ashanga borealis sp.n., is described from the Lower Cretaceous Yixian Fomation (Liaoning Province, P.R. China). The male forewing of the new species is similar to that of the Middle/Upper Jurassic species Ashanga clara Zherikhin 1985, but differs from it in possessing a forewing arched anterior margin, RS branching more basally, and MP + CuA1 with more branches. The fossil record of Chifengiinae is reviewed.
