Thanks Stephane! How did you get it? I am not a dipterologist but I have learned that Anthomyidae can be distinquished by cubital-anal vain and/or nonequal calypteres. Else?

Personnaly, I can recognize Anthomyiidae by experience, nethertheless, one can see the anal vein reaching the wing border on the female.
I have to disagree with the non-equal calypters. Only some genera (I think to Hydrophoria for example) have a lower calypter larger than upper one. Most of Anthomyiidae have small roundish equals calypters bordered with hairs (in the opposite of most Muscidae).
