Dear you all,

I just discovered this quite interresting paper "Review of the scolopaceus-group of Rhagio Fabricius 1775 with the description of a new species from the Iberian Peninsula (Diptera: Rhagionidae)"
So I took interrest to look at my specimens previously identified as R scolopaceus.

I have specimens from northern France with typical R scolopaceus'antennas, and I have specimens from Bretagne and central France with antennas like the picture following.
This is a male, last antennal segment is quite short, like R atlanticus, but arista is strongly concave, like R scolopaceus.
What to you think?
First sternite is strongly hairy.

Many thanks,
Clovis

Yes, nice article, isn’t it ?

In atlanticus male, eyes are dichoptic. Maybe the antenna is simewhat variable, but this looks good for scolopaceus to me.
