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.

The shape of the upper suture and the anterodorsal inclination of the katepisternal bristle are characteristic in Coelopidae. Tony ---------- Tony Irwin
