Thank you for the hint, that is very helpful!
Using this key: https://diptera.i...Europe.pdf I think it could be Neurigona quadrifasciata.
(Key on p. 102)
1 -> no hypopygium = female -> 6
6 -> mesonotum is yellow (not dark) -> 7
7 -> mesonotum is matt -> 8
8 -> abdominal tergites with black transverse bands -> N. quadrifasciata
Though I noticed that N. cilipes is not in the key. I can't find any information / picture from that species. Do you know whether it could be N. cilipes?
