Is this fly Malacomyia sciomyzina, Heterocheila buccata or something else ?
Mouth edge is projecting, there are meral setulae, no costal break, only lower calypter slightly developped.
According Seguy's keys, it might be Malacomyia sciomyzina, but I don't know this fly.
Sorry for the bad quality of the photo.

Sea coast, Saint-Jouin Bruneval, France.
12.VIII.2008
Size : 5.5 mm.

Another bad picture. I'll try to do better shots tomorrow...

Stephane -
Can you take a photo of the other side, so that we can have a good view of the katepisternum (=sternopleuron)? The shape of the upper suture and the anterodorsal inclination of the katepisternal bristle are characteristic in Coelopidae.

That's the only shot I managed to do, on another specimen. :@
It shows the ks shape and ks seta orientation.

Well, I think it looks good for Coelopidae - so I think this is Malacomyia. B)
