Salut Camille,

C'est bien un Malthodes, j'en ai quelques uns qui présentent une texture d'élytres comme ça.
Beaucoup n'ont pas de taches claires à l'extrémité des élytres, comme Malthodes holdhausi, qui a la même coloration que celui de la photo :

Cependant les Malthodes ne s'identifient qu'avec les genitalia mâles (c'est d'ailleurs assez caractéristique), et je ne connais pas de clés pour les femelles !

Amicalement,

Thank You, I guess it means it is Malthodes holdhausi but only genital examination would make it sure. I speak only german and english :)

Species within the generea of Malthodes and Malthinus are generally undeterminable from photos.

Xespok, which you say is known as in the text of Pierre! B)

"It is well Malthodes, I have of them some which has a texture of élytres like that.
Many does not have clear spots at the end of the élytres, like Malthodes holdhausi, which has same colouring as that of the photograph:
http://www.entomologie-stuttgart.de/ask/node/687&menu=ste

However Malthodes are identified only with the male genitalia (it is rather characteristic besides), and I do not know keys for the females! "

Thanks for all the infos. I do have tried genital examinations of male beetles, so far only Carabidae and Staphylinidae. I just leve this one as Malthodes sp.
