Hello,
I caught on june three male of Atylotus in subhalophile meadows.
I suppose it was
latistriatus but in comparaison with my specimens of
latistriatus I think it's more
rusticus.
One specimen shown here, 13.5mm.
Femur are more than half grey, notopleural lobe grey.
First antennal segment less rounded and strong than in
latistriatus.
No long hairs on front tibia (criteria not present in "The book" but find here :
https://www.flick...9222196896 and
https://www.flick...9587017873
With dark femurs,
fulvus and
loewianus can be excluded I suppose.
Am I right ?

I think so. The head in latistriatus is much larger than in rusticus, almost approaching fulvus. Could you provide a dorsal shot of the head ?

In comparaison with
latistriatus
rusticus is on the left. Head is not really less larger than
latistriatus on the right
The specimen on the right was caught in a halophile meadow, notopleural lobe yellow, hind femur largely yellow (as in some
latistriatus) and long black hairs on front tibia. Long hairs on eyes (
fulvus excluded).
First antennal segment of specimen on the left more elongated than in
latistriatus.

Is the criteria of long hairs on the anterior tibia a good element? A priori probably not, otherwise it would have been mentioned in the book ?
