Differential diagnosis

The male of Cheilosia flavipes has the combination of a bare eye, bare face, bicoloured legs, posterior margin of scutellum without setae and dorsal and ventral pile patches on katepisternum widely separated. These characters are shared with males of C. brunnipennis , C. megaclama sp. nov. and C. nebulosa . It has the basal three or four tarsomeres of the protarsus yellow (black in C. megaclama ), arista black (with orange base in C. nebulosa ), postpedicel ca 1.5 times as wide as high (ca two times as wide as high in C. brunnipennis ) and angle of approximation of eyes less than 90° (100–110° in C. brunnipennis ). Within the Caucasus, the female C. flavipes is easily identified by the combination of a bare eye and yellow femora.
