Hi fly people,

this one doesn't seem to key out with the fennoskandia key. It is form NW France, coastal habitat (foredunes), so could wel be not in the key...
There is a row of 5-6 Orb of which 2 are clearly bigger,
poc are crossed,
oc are seemingly missing (but can well be broken off),
no hairs on the ocelar triangle,
ocelar triangle is dark, shining in top halve, wrinkled in post half
arista is slightly thickened and clearly pubescent (hairs longer than width of arista)
first flagellomere is reniform, yellow but darkened at top side and at root of arista
Scutum is dark brown, evenly punctuated, with vague brownish stripes on scutum and pleura paler.
Setae on scutellum are not on ampullae, apical setae are a bit closer to subapical than to each other
Costal vein reaching vein M

thanks for any suggestion!
