The Axymyiidae is one of the small families of the suborder Nematocera within the Diptera. Up to date, three genera and seven species of extant axymyiids have been described from the Holarctic Region, including Canada, China, Hungary, Japan, Russia, and USA, with three genera and three species of fossil taxa described from the Middle Jurassic of Daohugou, northeastern China. A new genus Raraxymyia gen. nov. and two new species, R. parallela and R. proxima gen. et sp. nov. from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China, are herein described based on their well‐preserved wings and body characters. A revised key to the genera of axymyiids is provided.
