Differential diagnosis
Cheilosia uviformis is difficult to identify, mainly because it is inconclusive in two characters often used in the identification of Cheilosia : the sterna are only slightly pruinose, which could be interpreted as either pruinose or shiny, and in the female the eye is sparsely pilose, which could easily be missed and consequently, the eye pilosity could be interpreted as either bare or pilose (the eye is distinctly pilose in the male). It is very similar to C. psilophthalma , whose Caucasian population also has slightly pruinose sterna. It is distinguishable from C. psilophthalma by bicoloured claws with orange base and black apex (claws all black in C. psilophthalma ); the male by densely pruinose frons (shiny or indistinctly pruinose in that of C. psilophthalma ) and narrow parafacia, about half as wide as width of postpedicel (about 0.8 times as wide as width of postpedicel in C. psilophthalma ) and the female by sparse pilose eye (with distinct pile in that of C. psilophthalma ). For differences with other species of Cheilosia , see Bot & Van de Meutter (2023).

Genetics
DNA barcodes of European and Caucasian specimens of C. uviformis cluster together with high support (BS = 100%).
Remarks
Reported from the Caucasus for the first time.
Biology
Remarkably, only sampled in 2019 while areas of occurrence were also visited in other years. Collected between 14 June and 20 June at an altitude between 1800 and 2684 m a.s.l. All specimens were caught visiting willow Salix sp. catkins on alpine and subalpine grasslands.
Distribution
Europe and Caucasus ( Georgia).
