A new genus of Bittacidae, Mongolbittacus gen. n., based on Mongolbittacus daohugouensis sp. n., is described from the Middle Jurassic of Inner Mongolia, China. The presence of a four-winged specimen enables documentation of the intraspecimen variation of wing venation. Mongolbittacus appears to be related to the genera Orobittacus, Microbittacus, Mesobittacus, Preanabittacus, Anabittacus, Baissobittacus, Liaobittacus, Jichoristella and Antiquanabittacus because of the presence of three synapomorphies, i.e. MP4+CuA1+2 simple; Kreuz der Bittaciden (rp3+4 + ma–mp1+2 and mp1+2–mp3 crossveins) not aligned; and crossvein c–sp absent.
