Hi, can this be a species of Opomyzidae ? I have never seen one and I don't have any in my collection. Or is it just some of the Pallopteridae species ? Size 4mm and place Loviisa, Southern Finland today.

This is definitely not
Geomyza tripunctata. It is a female of the so-called combinata group. It is most probably either
Geomyza balachowskyi or
G. hackmani. Difficult to say after a photo.

Ok, then we have a new situation :) G.hackmani belongs to our species list but balachowskyi not. Is the difference in genitalia on visible ? Thank You very much !

I have to admit that there is a good chance that it is indeed
G. hackmani. There is a difference in sternite 8.

Ok, thank You again. I must do a good examination when I go back home. I will label it cf hackmani so far.

The abdomen of the females of
G. balachowskyi often has a more "striped" appearance. Furthermore the postscutellum is normally less dark in
G. balachowskyi. However both characters are not to be relied upon too much. To be certain, sternite 8 should be checked.

Thank's to Jan Willems papers I could find the ID :) Now I'm sure it's hackmani. The specimen was still fresh enough to get sternite 8 wisible.
