Kempyninae are a subfamily of osmylid lacewings whose extant representatives are restricted to the austral continents. Three new osmylids, Jurakempynus sinensis gen. et sp. nov., J. bellatulus gen. et sp. nov., and J. epunctatus gen. et sp. nov. are described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. The new genus Jurakempynus is assigned to the subfamily Kempyninae constituting its oldest known occurrence. It is allied to the Australian genus Kempynus, sharing two synapomorphies: extremely expanded MP space and distally forked
MP2 in the hindwing. The occurrence of Jurakempynus gen. nov. in China (Northern Hemisphere) implies a much wider
geographic range of the Mesozoic osmylid lacewings in comparison to their modern counterparts.
