Cheilosia (Taeniochilosia) grisella Becker, 1894
Remarks
All published references of this species in the Caucasus are based on Stackelberg & Richter (1968). Barkalov (1993) reidentified their material as C. aenigmatosa . Although he reported the species again later (Barkalov & Ståhls 1997), this is an error (A.V. Barkalov, pers. com.) and C. grisella should be treated as absent from the Caucasus.
Genetics
DNA barcodes of European specimens of C. grisella were grouped together with high support (BS = 98.7%). The cluster with the barcodes of Cheilosia lukashovae (BS = 100%) was placed sister to the barcodes cluster of C. grisella with high support (BS = 100%).
Distribution
Central Europe (Pyrenees, Alps, Carpathians) south to Montenegro, Serbia and North Macedonia, and eastwards to Romania and Bulgaria.
