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. Kind regards, Sandra |

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 R4+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 
Kind regards, Sandra |
