There's one more Anthomyzidae species which was kindly identified by Dr. Jindrich Rohacek.
08.08.2006, Bekasovo-1 station, Naro-Fominsk district, Moscow region.
Very small, size around 1.5mm.
According to Dr. Rohacek,
This female belongs (I believe so) to Stiphrosoma laetum (Meigen, 1830). It differs from S. cingulatum by darker pattern on abdomen and brown sides of occiput (the latter not well visible on photographs). This species is usually larger than S. cingulatum but this not case in your specimen. It is also a terricolous species living in tufts of grasses and other graminoids.

Hi Dima,
The pattern on the abdomen indeed seems to be different from that of the specimens that were identified as
S. cingulatum (see gallery). Identifications like this are the work for a specialist (like Dr. Jindrich Rohacek) to my opinion.

Hi Dima,
In The Netherlands we collect yet another species of
Stiphrosoma (
S. sabulosum) the most. This is a species with strongly reduced wings (although also macroptere specimens are known (but not from The Netherlands)). Most of the
S. sabulosum material from The Netherlands has been collected by means of pitfall traps.

Thanks for the collecting hint Jan - I also noticed that Stiphrosoma has wings considerably shorter than these of Anthomyza.
