Starting with this thread I would like to submit several species of anthomyiid flies (family idetification has been confirmed by specialists of Russian Zoological Istitute) for consideration. I know this group of flies is very difficult for identification, but maybe someone knows these flies very well and can id them by their apearance at least down to genus level. All flies have been caught in cereal crops in Central European Russia (Voronezh region) last summer.
The given specimen has 3-4 mm long.
Thanks advance, Sergey.

Hey! Can somebody offer me his supposition what genus this fly might be?
Maybe Delia sp.???

Reminds me of Atherigona (muscidae) but I may be completely off. Kahis may correct me.

It really reminds Atherigona, but I don't think it may be Atherigona. Long antennae 3-d isn't only Atherigona feature, Atherigona has base of antennae almost at the same level as upper eyes margin, this fly - in rather "normal" position. And the only Atherigona which may be (hardly) in Voronezh region - A.varia with yellow pleuras.
And Sergey, if it is female of Anthomyiidae than even collected specimen is very difficul (or so far impossible) to ID.

Hi Sergey
I doubt that this is Anthomyiidae - it looks much more like a male Coenosiinae (Muscidae). (Possibly Spanochaeta dorsalis? - check the genitalia.)

I think that here the most probable answer is
Coenosia nigridigita/rufipalpis.
