Differential diagnosis

Cheilosia bakurianiensis 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 occurring in the Caucasus, the male can be identified by the combination of pruinose sterna and shiny parafacia. The female is easily separated from the other Taeniochilosia taxa occurring in the Caucasus by the wide face, broader than an eye at level of antennal base.

Genetics

All DNA barcodes of C. bakurianiensis are resolved into a cluster with high support (BS = 100%).

Remarks

This species has been reported from Georgia ( Mengual et al. 2020). We provide the first records from Armenia.

Biology

During our expeditions, collected between 10 May and 9 June at an altitude between 1820 and 2519 m a.s.l. Almost all individuals were found feeding on Caltha palustris and Ranunculus sp. near wet seapages in alpine meadows.

Distribution

Caucasus ( Armenia, Georgia). Presence in the Russian Caucasus doubtful ( Barkalov & Mutin 2018).
