Hmmm - I had a E. bohemani once (http://www.dipter...pid=140513) and it had a very conspicuous, quite dark, wing venation... The fly under concern has a much less "visible" wing venation independent of light and camera angle. Then, in Tschorsnig & Herting 1994 I read that in Estheria the dorsal excavation of tergite 2 reaches the margin. This seems not to be the case in my fly. Can you please inform me a bit more in detail why this is an Estheria for sure - does the petiolate venation beat the other characters? I add one more picture. Thanks!
