Yes, I agree Fannia atripes the surstyli and cercal plate are a very good match for Fonseca's drawing of the terminalia.

Re: Fannia atripes from French Brittany ?

Thank you for your opinion Nigel !

With the Rozkosny - Gregor - Pont (1997) and   Bartak & al (2016) key's, to obtain Fannia atripes, we need to have fore coxa without spines on lower inner margin but here we have a spine on lower inner margin.
Fannia manicata don't match because mid tibiae are not dilated. For Fannia monilis, it's the terminalia than don't match. 
That's why I continued the key which led me to Fannia atripes ... a specie apparently not known for France.

Have you more information on this specie ?

Thank you again.

The images attached are taken from the "A Provisional Assessment of the Status of Calypterate flies in the UK". It is a rare fly in Britain.
