Hello,

Another specimen from the trap on Amager not far from Copenhagen.
When using Spencer (1976) I key this one out without much ado to either A. mobilis or nigrociliata, but that is evidently wrong ... The fly has a reduced pre-sutural dc, 3. antennal segment black, costa to R4+5 and dark squamal fringe. But I don't find any resemblance in the genitalia to the two species. And I don't know ... isn't the aedeagal apodeme missing? I'm almost sure I'm not to blame ;)

The picture shows the genitalia in lateral (top) and ventral (bottom) view. What species might it be?

Collected from malaise trap 20. - 24. June 2017.
