 I think it's Orbellia.

 Thank you! Which parts are needed to say it's exactly this genus?

Are there three pairs of bristles on the margin of the scutellum instead of the usual two? In North America that would be enough.

 With this key it appears to be nivicola, right?

 I find the last couplet difficult. The postpronotum contrasts with the mesonotum, but is not brownish.

 Let me write something about the key I prepared and published ij Dipteron-Wrocław.
The key was constructed to the Orbellia species hitherto known Russia.
One well known European species, O. myiopiformis wasn't included there...
I'm still working on the morphological differences between O. myiopiformis and O. nivicola (Both of it are closely related). If the specimen was collected, please contact me using PM to send it to me for further examination.
I have received next specimens of Orbellia from Chuvasia, which are similar to both mentioned species... Andrzej

 No, sorry, I don't like collecting if I don't have a purpose to do so.
But if there are differences between them other than genitals maybe I have photos that show them, I spent a long time with this individual.

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
