Hello,

I photographed this Asilidae in September, 2019 in Lyon (south-est of France). I don't have a size or an estimation of the size.
I think it's an Asilinae and one of my collegue suggested that it could be Tolmerus atripes.
What do you think of my Asilidae?

Do you have more pictures? This creature looks too robust to be Tolmerus atripes. That species has a mainly black mystax. It looks to me as if the left hind tibia has a reddish base but I'm not sure. Can you confirm that? I would say it is a Machimus female, if the base of the tibiae are reddish than this could be M. fimbriatus. A rather large Machimus species. If the legs are entirely black it becomes near to impossible to ID this one.

Unfortunately I don't have pictures from another angle of view...
Here an enlargement of the left hind tibia, effectively it seems to have a red base!

:-) Surely the right left tibia has a red base. Because of the mainly white mystax it could be M. cf fimbriatus but I can't be sure.

So we should call it "Machimus cf. cf. fimbriatus" :D
But at least we have the genus!
Thanks!
