Anthomyiidae. Alliopsis sylvestris species group female, but not sylvestris which has less widely separated eyes.

If the interfrontals are plased just below the ocelli ( I just can't see them on these photos, but it seems so) and with the fore tars on tibia 1 enlarged.....this could be Alliopsis denticauda.

I need a sharp photo from the head (front)...!

Please.....Try to read my answer properly (or translate my tekst with a program on the internet) and take not just an answer for granted.
I have asked for an enlargement of the head, before I can be sure of my answer !!!

According to Griffiths denticauda is a gray species with tarsomeres 2-5 of uniform width. This belongs in his sylvestris superspecies with only tarsomeres 2-3 enlarged.

That is why I had my doubts...!!
I only have Hennig and Ackland for Alliopsis and not Griffiths to consult.
In Hennig only A. denticauda was mentioned with the enlarged tarsomeres, that is why I thought it could be A. denticauda.
So John, thank you for the information, and I am saving the money to buy more parts of Griffiths (or lend it from the library)!
Alliopsis sylvestris species group it is..!

Griffiths includes six species known from the Palaearctic:

A. silvestris. Eyes separated "by slightly more than width of ocellar tubercle", pulvilli of fore legs almost as long as fifth tarsomere.

A. teriolensis including borealis. Eyes more widely separated, at least in some populations.

A. lutebasicosta (Fan)
A. silvatica (Suwa)
A. maculifrons (Zetterstedt)
A. billbergi (Zetterstedt)

By range this should be teriolensis ("from Tyrol", I presume).

Griffiths' only female specimen was from Scandinavia, and the Alps population may differ. If you don't have Hennig's description I can copy Griffiths'.
