Thank you Robert.
Unfortunely photo isn't as good I wish. This fly dislike flash and move every time.
I excluded Ph. bitincta for two reasons:
- all grey scutellum
- bare arista. I think it is visible on large photo I'm adding now.
It seems to me that presutural ac - 2, but not as stong as dc, for example.

P.S. Of course, you can show this photo.
