Type species: Mydaea scutellaris Robineau-Desvoidy, 1830 (by subsequent designation of Coquillett 1901). Xenomydaea Malloch, 1920: 144. Type species: Xenomydaea buccata Malloch, 1920 (by original designation). Generic diagnosis. Meron and anepimeron bare; katepisternal setae 1+2; lower margin of posterior spiracle without row of setae; Sc bent bow-shaped; dorsal and ventral surfaces of radial node with hairs, M1 straight; lower calypter tongue-shaped; mid tibia with at least 2 p ; hind coxa bare on posterior surface, hind tibia without pd. The cerci of all Chinese species have been divided into seven different kinds. We figure together these seven kinds to show there differences ( Fig. 1 ). Figure 1.
