Strange that M vein..
seems a Dalmannia sp. (Conopidae) Dorsal shot to see the abdomen... is it possible?

Thanks Jorge, I will tell my Conopid man about it. Looking in the Gallery it is not D. dorsalis or D. punctata, that leaves D. aculeata, D. confusa and D. marginata - known from Europe - I am off to search for images elsewhere.

According to the key at
home.hccnet.nl/mp.van.veen/conopidae/
it is D. marginata because of the all black scutellum (not visible in the pictures, but i asure you it is all black), however this key does not include D. confusa, so I still don't know for sure.

Yes, it's Dalmannia marginata (Meigen, 1824)
Dalmannia confusa is a synonym of Dalmannia dorsalis, and that species has at least some yellow at the humeri (shoulder), but most of the time also on the scutellum.
