All this discussion is rather useless and not scientific. Genera are classified on the basis of characters, not resemblances. Have you identified the tribe using the keys (here)?
In order to include or exclude Saperdini, we have only to know the shape of the epimera (here). Are they like in this group?
And yes we do what we can with what we have and there they are only photos so we extrapolate we exchange and that's all... We put forward ideas....... knowing that obviously nothing is excluded concerning the tribes. And on the scientific side, I'm not a scientist now! That's one thing for sure!
