Pseudodoros (Dioprosopa) clavatus (Fabricius)  

Pseudodoros is a genus of Syrphini with three species. The most common and wide-spread species is P. clavatus, which has eye bare; metasternum bare; thorax without yellow maculae except on scutellum; postmetacoxal bridge incomplete; vein M1 slightly sinuate; vein R4+5 straight or nearly so.

Following Kassebeer (2000), the subgenus Dioprosopa has tergum 2 with a pair of basal, large, triangular yellow maculae; scutellum yellow, with medial dark brown fascia; scutum with short, half-lying pile; pro- and mesotibiae yellowish-red to brown anteriorly, much darker on posterior 1/3 to 1/2; medial black facial vitta wider than the basoflagellomere's width; mouth edge black. This subgenus is only found in the New World.
