Georgia (Transcaucasia), 01.04.2017
The species appears in February-March (depending on temperature), prefers open steppes. In windy weather is found under stones and rocks on eastern slopes. Last year I've published the photo of the same species, unfortunately it didn;t give any results. Maybe this one will bring some clearance... Dark ventral side, bluish eyes and bright yellow dorsal side. Males and females have similar coloration.

I didn't mention the size - 8-10 mm, also there are specimens 1.5 size of it.

Not even the genus? :|

Armen, the genus is Bombylius but there aren't active experts in this family in the forum :( That is why you don't get an answer.

I am only an amateur and Eastern species are pretty unknown to me. I can try to do some searching in a few days (impossible at this moment). A bit of patience and hopefully I'll tell you something soon :)

Best

Piluca

Hi, Piluca!
Thank's for your response and for the attempt to help me with determination. I really appreciate it! :)
Also I've tried to resolve the puzzle by myself, using key from "Parasitic flies of the family Bombyliidae (Diptera) in the fauna of Transcaucasia", (Zaitsev. 1966), I wasn't able to find any description of neither Bombylius, nor Systoechus, reassembling the fly :(

Here's an old pic of the same fly I took last year in February, hope it will be helpful.

Hm...I've looked through and old russian-languaged key and now think it maybe Systoechus laevifrons (couldn't find any information on internet about the species), and here's the translation of description:

"Face and forehead covered with dense black hair (without bright ones)..."B)

And there are also the drawings of female and male. (see attached file). The problem is I don't know whether the species is valid or not.

It comes close to Bombylius trichurus (ex B. fuliginosus) to me.

Oh wow! This is the best suggestion from all! Seems to be true, also the species is present in Georgia and Caucasus as well. Thank you, my friend!
