female - Berlin - May 2018

I figure that this specimen is Rhinophoridae based solely upon wing venation. I checked against the list of Rhinophoridae for Germany and Tricogena seems to match. Anyone confirm?

I have only seen Phyto melanocephala of Rhinophoridae, so i am not positive that this id is correct. I have no reference material for this family. Any know of keys with genitalia?

Thank you for your time.

That is a yes.

But you cannot recognize a Rhinophorid on wing venation.... you need to check the postscutellum

Thank you, Theo. Thanks for the tip as well. Good to know.

I actually thought it was a Tachinid at first glance. I made a few photos then i realized that it doesn't appear to be a Tachinid. I thought about Rhinophoridae and ended up at Tricogena. Very interesting fly. I don't see Rhinophoridae very often or i don't recognize them very well. One thing that bothered me is the hairy face. The orange of the antennae isn't always visible. The red bristly legs still makes me think of a Tachinid. Good thing i didn't try to key it as a Tachinid :)

Trichogena (or whichever spelling you prefer) is indeed the most Tachinid-like of Rhinophoridae. The very large genital in male and yellow second antennal segment in female make it easy to recognize, once you know the species.

Yes, i almost mistakenly tried to key it as a Tachinid. Something reminded me of Phyto. I guess i got lucky this time and made the right decision. Otherwise, i might be banging the keyboard all day trying to find a match with Tachinidae. I will definitely remember those antennal segments. Hopefully i can find a male.

I Thank you very much, Sir. You are a big help and i appreciate it :)
