 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.
