Hello,

Dolichopus seems correct (hind basitarsus with small pilosity). I tried Grichanov'skey but had to give up after a few couplets.
However, the fore femur is yellow.

Can somebody give me a clue?
Thanks in advance.

Probably Dolichopus ungulatus. That is the most common species with more than one bristle on front of hind femur.

John,

Thanks for this proposition and for the criterion.
