Hello, Found in a garden, in France, Oxelaëre, the september 13 2014, Maybe a Muscidae (or a Anthomyiidae ??) ?

It has 4 post dc, and it doesn't look any Egle, so not Anthomyiidae. It is probably a female Hydrotaea (I can't see any pd on t3, are they broken or absent - some species haven't any pd on t3, like Hydrotaea floccosa). I have just little doubt with Potamia littoralis : the genae seem as high as postpedicel, if they were higher or if the arista were short plumose, it would turn to be this genus/species.

Thanks you very much, Stephane !  On this picture I think the arista is short plumose, so it should be Potamia littoralis ? Renko attached the following image:  [58.66Kb] |

From what I can see, the hairs are at most as long as arista base, this is called a "pubescent arista" and is not enough long for Potamia, but OK for Hydrotaea.
