Differential diagnosis

Cheilosia pollinifacies belongs to the subgenus Taeniochilosia by the combination of bare eye, black legs and the anterior process of lunula not broadly confluent with the face ( Barkalov & Ståhls 1997). Within Taeniochilosia , it is similar to C. aenigmatosa . For a diagnosis between the two species, see the Differential diagnosis under C. aenigmatosa . The male genitalia are figured in Barkalov & Ståhls (1997).

Material examined

Collected in 2018, 2019 and 2021; see Mengual et al. (2020) for detailed records from 2018.

Genetics

All DNA barcodes of C. pollinifacies cluster together with high support (BS = 98.6%). See also Remarks for C. aenigmatosa .

Biology

During our expeditions, collected between 9 June and 31 July at an altitude between 1797 and 2630 m a.s.l. Most common on alpine meadows where it feeds on the flowers of herbaceous plants

Distribution

Caucasus ( Armenia, Azerbaijan, Georgia, Russia).
