Differential diagnosis

Cheilosia subpictipennis belongs to the subgenus Montanocheila and is very similar to the sympatric occurring Cheilosia rufa sp. nov. For differences, see the Differential diagnosis under Cheilosia rufa sp. nov. For diagnostic characteristics of C. subpictipennis from other European species of Montanocheila, and for figures of the male genitalia, see Claussen (1998).

Material examined

Cheilosia subpictipennis was not collected in 2018, but collected in 2019 and 2023.
