Differential diagnosis

Cheilosia teberdensis is a member of a group of closely related species, called the proxima group (Vujić et al. 2013) in which the pilose eyes, posterior margin of scutellum with setae, usually partly yellow legs, continuously pilose katepisternum, pruinose sterna and the shape of postgonite are distinctive characters. For a full diagnosis of the Cheilosia proxima group, see Vujić et al. (2013). Cheilosia teberdensis stands out, together with C. paragigantea, from other members of the proxima group occurring in the Caucasus by having black legs (tibiae yellow at both ends in the other species). Similar to C. paragigantea; for differences, see Differential diagnosis of that species.
