Hello,

Olivier Durand collected this female in Longué-Jumelle (centroid : 47.375956 , -0.109574) on 28/07/2013.
It's a Dasyrhamphis, quite rare in north of France.
Subcallus brown, first antennal segment quite brown too. Wing with central part of cells hyaline. greyish hairs on margin of all tergites.
Some characters could be close to anthracinus but this species is certainly impossible here. So it could be ater ?

D. ater is annoyingly variable, real anthracinus are very obvious in my experience, so ater is fine by me.
Yes, pretty far north, it has been found before along the Loire.
