OK.. another (un?)educated guess ;) If R1 is bare and R4+5 has hairs extending to the node then I get to Belida angelicae in Belshaw's key. But I have never seen this species (it is only known from 1 UK record) so I have no idea if that is even close. But the postpronotal lobe does appear to have hairs forming a forward-pointing triangle and the middle leg has lots of ad-bristles. :)

Hi Chris.
R1 and R4+5 are both bare, but there are 3-4 strong setas on steam R2+3-R4+5 right before place where it divides on two different veins.
Waiting for another information requests,
Nikita

Hi Chris,

Right tribe (Blondeliini), but Belshaw can save you here.
This is Lecanipa bicincta, a central and eastern European species.
The abdominal pattern is somewhat remniscent of Thelaira females.
The eyes are hairy and the facial ridge has strong bristles all the way up. Tibia 2 has a row of strong ad bristles.

By the way Nikita, nice picture of not so common species !

Excuse me Theo, but in my key:
Lecanipa bicincta has 3+3 ac and setas on R4+5 from base till rm.
But my fly has 2+3 ac (if I?m not mistaken) and only 3 seta only on base of R4+5 (clearly visible under microscop) as Lecapina leucomelas.

So:
I was wrong 3+3 ac. But still only 3 setas only on base of R4+5. More, it sems that fly on photo on the contrary has setas from R4+5 base till rm. Image and collected fly in same 5m2, image 10-15 min before.
And another question. In genera key to Lecanipa lead teza:
- M1+2 curve without appendix ? which is correct in my case
- R4+5 reach wing margin near wing?s top ? which is not correct (obiosly before).
Some mistake in my genara key?

It is fragment of large image of Lecapina I send.
If I it is setas on marked area, so the only explanaition I can find is on photo L. bicincta, but collected L. leucomelas or fly lost setas in exgauster.
