Differential diagnosis

Cheilosia (M.) distincta is among the Nepalese species closest to C. (M.) erratica . Cheilosia erratica differs by having tergite III entirely yellowish pilose, while C. distincta has tergite III black pilose.

Taxonomic remark

The description of Cheilosia (M.) distincta Barkalov & Cheng, 1998 agrees with the description of Cheilosia hirticincta Brunetti, 1915 in almost all described characteristics. The studied specimens from Nepal, one male and six females, have basoflagellomere reddish-brown with light greyish dusting and blackish dorsal margin (described as black with greyish dusting in Cheilosia distincta and C. hirticincta ). The NHM (London) has six male specimens identified as Cheilosia hirticincta Brunetti. The structure of the male genitalia of Cheilosia (M.) distincta and C. hirticincta is very similar. However, we have not been able to locate and study the type material of C. hirticincta to evaluate a possible synonymy of C. distincta .

Distribution

China, Nepal.
