Thank you Paul. It is a grate pleasure to me that I came to same conclusions. I have 1 female and 2 male. So I started to investigate genitalia. It is hard job unexpirienced person, but I decided that it is rather C. pictipes than apicalis. Another reason was that if we can not to distinuish species by photo, so we can sign photo with name of more common out of possible species. So I did.
During my next visit Andrey Ozerov in Moscow Zool Musem I'll compare my flies with musem material, hope it helps to find final answer.
