Merci Stéphane, a new family for me :) Only 4 species in France and I find a key ; I'll try to go further.

With the key I go to genera Aphaniosoma because occiput seems concave.
Is that right ?

It is not Aphaniosoma : the acr are in numerous rows (7-8) and the pvt are cruciate.
If the occiput is rather flat, it is Gymnochiromyia (not in your key).

A closup of the scutellum could be useful too...

Sorry Stéphane I have no better close-up of the scutellum.
That small fly would run non stop and I got only that two shots.
