Breuning said about P corrugata : "... tous les points de la surface et des jambes entourées d'un petit cercle noir...". It seems like that, but to confirm.
Thank you to both for the help!! I don't know see these black circles on the points... Somebody has a picture of this species for look these characteristic black circles??
This is the picture of the elytra of the Paraleprodera corrugata, from Breuning Etudes sur les lamiaires 1942-1946. The drawing not is exact to my specimen...
