Moscow region, 08 june, near pond, 5-6mm.
Forked M isn't visible, but as Paul once reply me " such a build could be only Sciapus". Sciapus.
Malechance! I forgot in Moscow all my equipment, pins ect.
Antenae black, it leads to S. laetus. But this species 3,5mm only and anyhow name seems not valid anymore.
Help please.

Not Sciapus. These are more slender. I think Rhaphium or maybe Argyra.

A lot of times I told myself: Nikita, if you can't find right siutable species, try to look for right genus!
Thank you Paul. New genus for me!
I think Argyra (Rhaphium - 6dc and darkened wings).
One more image add.

This lateral view is Argyra (? diaphana).

The 2nd photo is definitely an Argyra, but not diaphana

Well, with microscop and Argyra diaphana (http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=1994) to compare with I tried to ID.
1. Scutellum obviosly not hairy.
2. Thorax white-dusted (not obviosly, but well enought).
3. Face is black.
4. Antenae 3-d more than 1,5 longer than its base.
5. All f - black
6. Yellow spots on 2 and 3 tergits of dusty abdomen.
7. In addition 1,5mm less than A.diaphana, as it has to be.
Argyra argyra.
Correct?
