Differential diagnosis

Cheilosia lasiopa has face and eye pilose and legs black, except base of tibiae yellow. It is similar to C. borjomi sp. nov., C. melanopa , C. redi and C. variabilis , but it has short setae on posterior margin of scutellum, shorter than scutellum length (longer in the other species), tibiae black with yellow base ( Fig. 38C) (usually either all black or with yellow base and apex in the other species) and in the male the dorsal lobe of the postgonite is as long as the ventral lobe (shorter than ventral lobe in the other species, see Francuski et al. (2009) for drawings of the male genitalia).

Material examined

Genetics

Distribution
