Looks like a Stackelbergomyia sp., but I have never seen one :)

Erikas, thank you! As you guess I have never seen this creature too. It fits the description completely.
My wrong idea about Oestroidea seems pardonable: proboscis is very much reduced. During long time this fly was in a specially made family Stackelbergomyiidae.
Now - Phasiinae (to my surprise).
Chris, come Russia.

Wow ... a very odd phasiine indeed - I would not have guessed either.

Those narrow calyptrae reminds only representatives of Rhinophoridae, some of Phasiinae, Macquartia, but wing venation is very characteristic for this genus. Would be nice to the gallery!

Neither the image, nor the specimen are good, but of course the fly itselef is worth the Gallery. Done.

Theo, could you comment the reasons of placing this creature in Phasiinae?

Herting (1981) placed Stackelbergomyia in Tachinidae.

He wrote:
"Die Fliege findet wahrscheinlich in der Subfamilie Phasiinae, Tribus Catharosiini ihren richtigen Platz, denn sie besitzt die folgenden Merkmale: ... Calyptera klein ... Genitalien des männchens erinneren ebenfalls an die Catharosiini ... fast rudimentäre Rüssel ... und das teilweise membranöse Postscutellum finden sich auch bei Catharosia flavicornis ...".

Thank you Liekele for this information.
(The fly will probably be Phasiinae subfamily, tribe Catharosiini their proper place, because it has the following features: ... Calyptera small ... Of the male genitalia are also reminiscent of the Catharosiini ... almost rudimentary proboscis ... and partly membranous Postscutellum are also found in Catharosia flavicornis)
