Widespread, but not common, on the stones near streams, 5mm.

I think, I found the answer. Another fly collected (looks like same genus, but another species). I think it is Lauxaniidae, Homoneurinae, new species of Prosopomyia. Tomorrow I'll go to search more. Nikita Vikhrev - Zool Museum of Moscow University |

Several features on this fly (head profile; size, shape and angle of wings; mid tibial spurs) suggest that it is mimicking an auchenorrhynchan homopteran. Why would it do that, I wonder?

Hehe, for some predatory insects it is no use to try to catch hoppers. These simply jump away too quickly. So if a predator thinks you will be long gone before you can be caught, well I guess that might be advantageous.

I am not familiar at all with the flies from the Far East. When I saw Nikita`s photo I thought immediately about Peplomyza, a Lauxanid genus. Peplomyza keep its wings very similarly.

And this fly lives on large stones in forest streams (it is why not easy to collect). Being disturbed it goes aside like Cycadellidae.

Yeah, that grey matter here above sometimes does what it is supposed to do.

I've got news that Shatalkin ID fly as species of genus Cestrotus. As far as I understood it is difficult genus with flies from Afrotropical and Oriental region and species level ID takes some good time. I found 1 image in i-net in: http://www.museums.org.za/bio/insects/flies/lauxaniidae/index.htm Nikita Nikita Vikhrev - Zool Museum of Moscow University |
