Hello,

At first sight, I thought it was a Poecilobothrus nobilitatus, but it appears that this is a male and since there is no whitish spot at the apex of the wings, this hypothesis is wrong.

Anyone can tell me more? Thanks in advance.

I shall check distribution later.

Or perhaps the west european look-alike species, Hercostomus vockerothi ?

Thanks to both of you.

A genus is already wonderful for me, if we have to remain in the doubt.
