Hi,

From a friend in the North-East of France, october 23rd 2019.
It looks like Calythea nigricans male, is that correct ?
Thanks for help.

Calythea seems right, but there are two species (C.pratincola and C. nigricans) and the differents between those two species is very difficult to make on photos, but C.pratincola should have a long dorsal seta on the fore tibia, which not seems present on your photos, ….so very good change it is indeed C.nigricans.
