Hi,
who do we have here ? Some kind of Diastatidae maybe ? This very beautiful fly was in my malaise September 15. 2009 in Helsinki Finland.

If this belongs to
Diastatidae, couldn't it be
Diastata costata, the slightly darkened costal region of the wing would suggest so?

Yes, possible. When I use my old Lindner (key by Duda) it keys out as
fuscula. The book says, that
costata is synonym of
fuscula but but .... In our list of species we have both
costata and
fuscula :o

Lindner is out(dated) again, try Chandler's revision in Ent. Scand 18 (1987).
