From first sight looks like a Linnaemyia ..

Yes, it is a Linnaemyia.


Moreover, it is a male with proclinate orbitals !!
That should be a big clue (L. comta ?)

I took the key halfway. I was wrong especially early in the season, too many things forgotten;)
With the key, the second segment of the antenna corresponds to figure 50 and not 52.
If in this genus, only the comta species has a male with oe so it's good.
But the key is for all species present in France?

No, key is incomplete for France.

However, if sternite 1 has light hairs, you are pretty sure OK.

Yes, the hairs are light ventrally on sternite 1.

Thank you

Nice find - that's a particularly rare species here in the UK and I have only ever seen 1 ... in a sample from Russia :)

It is not that rare in the south of France.
