Differential diagnosis

Cheilosia nigripes 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 it can be easily identified by the shiny sterna II– IV (pruinose in all other Taeniochilosia in the Caucasus). Cheilosia nigripes from the Caucasus is morphologically slightly different from specimens studied from Europe and the Russian Far East: the male is more extensively pruinose, with the frons, posterior anepisternum and katepisternum pruinose and the pruinosity on anterior part of scutum reaches lateral margin; the scutum is slightly less coarsely punctured; pile on lateral margin of tergum IV longer, more erect and usually yellow; and pile on lateral part of sternum III longer. Females from the Caucasus are also more pruinose on the posterior anepisternum and katepisternum, and the pruinosity on anterior part of scutum reaches the lateral margins of the scutum. Due to the more extensive pruinosity, the Caucasian individuals are very similar to extralimital C. vicina ( Zetterstedt, 1849) , although the pruinosity in C. nigripes from the Caucasus is less dense and the clypeus shorter (in the mid-line, at the most 1.25 times as long as its maximum width vs 1.75–2 times as long as its maximum width). The male genitalia are figured in Barkalov & Ståhls (1997).

Genetics

In our NJ tree we have a cluster with high support (BS = 99.9%) comprising the barcodes of C. vicina , C. sahlbergi Becker, 1894 , C. impudens Becker, 1894 , and C. nigripes . Within this cluster, all sequences of C. nigripes from Europe and Caucasus are grouped together with one barcode of C. impudens .

Biology

During our expeditions, collected between 30 April and 9 July at an altitude between 750 and 2758 m a.s.l. C. nigripes was seen feeding on low herbaceous plants as Ranunculus sp.

Distribution

Palaearctic. Within the Caucasus known from Azerbaijan, Armenia, Georgia and Russia.
