摘要
Rhagionidae is one of the most primary families of the lower Brachycera. Many rhagionid genera and species have been found in the Mesozoic. Their fossils came from Asia, Europe, Australia and North America. In the present paper, descriptions of a new genus and species of Rhagionidae from the Middle Jurassic of China, Achrysopilus neimenguensis gen. et sp. n. and a key to genera of Chinese fossil rhagionids are given.
