Looks like a
Ptiolina (unless it is very small, 2 mm or less). If you have a few you can spare I can confirm under the microscope.

I'am sorry, I did not mention the size. They are about 3 mm. :)
I thought the antennae didn't fit Ptiolina.
You're going to recieve some soon.

The antennae are indeed not
Ptiolina-like, but the only alternative I could think of in Rhagionidae was
Spania (smaller than
Ptiolina) but that gave the same problem.
In the picture it is not visible there is a small apical stylus on the tip of the arista and that excludes Rhagionidae. Then remains only
Ragas unica (Brachystomatidae, formerly Empididae). The shorter fork in R
4+5 miht have set me on the right track but those two specimens I received today are much more easy to work with. ;)

Many thanks for the explanation and ID!!
I can imagine it is easier to work with the specimens themselves |t
