Hi Vladimir,
probably Villu is right.
I didn't pay too much attention at the ovipositor, because it is not well visible.
I had a look only at the picture of the ventral surface. Anyway, this picture is not good enough for ID, because the sterna are almost fully black under this angle, and the we cannot see the face in frontal view.
Actually these two species are easy to separate, if you look at the right characters. Here you can see together the beautiful pictures taken by Alex Berg:
You can compare them with your specimen and confirm which species you collected.
Cheers
Paolo
