No. the ground colour of postprontum is dark. The greyish dusting does not count. In decolor and oicta, it is yellow, not white.
Moreover, the antenna is dark.
Finally the topcell is open, whereas it is short petiolatedmin picta and petiolata, at least in Europe.
So, this one does need key out.
Might be an aberration, might be a new species.
Only collecting material might resolve the matter..
