Thank you by your aid. Lamentably at this moment I have not photographic machine, but later I will try to post another picture of the species that I have, which is something more greenish in colour, but now believe that in fact is P. testaceovirens.
I reiterate thanks to you for your help,

Carlos

Hola Carlos,
I can send you by private message the description (in french !) of this species by Soula (revision of Pelidnota 1 and Lasiocalina) so that you can compare it with your specimen ...

Dear Francois:

That will be very interesting for my!!

Saludos

Carlos
