Hello Nikita Vikhrev,

Looks very interesting, but without any useable features for ID. Probably a Tragopinae close to Traginops or Schildomyia….

Regards,

Ectemnius

Thank you, Ectemnius.

Heh,

Fooled! It's a Ulidiidae, Callopistromyia annulipes looks most similar. Although that species has more dots on the wing....

Regards,

Ectemnius

See if it fits in Kameneva and Korneyev's revision of Myennidini. It reminds me of Pseudotephritis.

John is right. Here is a key to the known species: http://www.entomology.org.il/sites/default/files/pdfs/p.497%20kameneva%20and%20korneyev.pdf

Thank you Ectemnius!
Thank you, John!
(I started with Ulidiidae, but overlooked Callopistromyia.)
Callopistromyia has a curious distribution. Even more curiious is that in the Gallery the wing pattern of specimens from Europe and USA is the same, while it is clearly different in Sberian specimens (so far we have 1m and 1f and a bad weather).

Hi Nikita,

Yes, Callipistromyia is an originally Nearctic fly recently found in Europe. But yours is a Pseudotephritis. Either P. corticalis or P. millepunctata.
Based on the drawings in Kamaneva & Korneyev I'd say: P. corticalis.

Regards,

Ectemnius

Thank you again, Ectemnius and John.
Yes, I have got Kamaneva & Korneyev paper and my fly looks like Pseudotephritis corticalis, thou wing pattern differs.
At first glance, I would like to express my doubts in the validity of the genus Callopistromyia: for example, the same butterfly-like wing pattern around ta vein convince my more, that hairy or bare lateral surface of the abdomen.

Correct, Nikita!
Concerning "validity" of the genus (IMHO, only names are "valid", but that's garbage issue, right?) -- there is a phylogeny of the the Myennidini in Kameneva & KOrneyev 2006. which clearly shows Callopistromyia to be a part of the NA Oedopa lineage. The Holarctic "Pseudotephritis" corticalis generally lies out of the two main clades and obviously needs its own genus; however, I'd prefer Tanya Galinskaya do such a job with the molecular data should she obtain a fresh stuff from Russia.
This species has been recorded from Mongolia by Soos and from Luga by Hennig (Stackelberg's material). It is very rare compared to other Myennidini, but occurs on wet logs as well.
