I came quickly enough to Hyperoscelididae (which I understand is Canthyloscelidae now) in Stackelberg's family key. Now I'm pretty sure it's a Hyperoscelis eximia. May 20, 2008, Naro-Fominsk, Moscow region, Russia. Size 5 mm.

Yes, it is almost certainly Hyperoscelis eximia. However the best character for separating this species from the vicinous H. veternosa (shape of dark pigmented part of base of vein M after Rohacek & Bartak 2007) is not clearly visible in this picture. Anyway, both species are flies of rare occurence ! |

Many thanks Colobo. In Nagatomi and Saigusa (1984) two external distinguishing characters are mentioned (after Mamaev and Krivosheina (1969) and Hutson (1977)), that is: 1) vein between cells SM and P1 is shorter than (in veternosa) or as long as (in eximia) than that between cells M and P1, I understand that means corresponding lengths of R4+5; 2) thickened part of the vein between cells B and P3 is parallel (in veternosa) or not parallel (in eximia) with vein R1. I've checked the specimen and according to 1 it's rather veternosa but according to 2 it's eximia. These two are not very reliable characters, though.
