stupidus-dumasi
This one is definately stupidus. Dumasi has very distinctly hairy pronotum. No ruse, different species.

Stupid, not dumb
There's another, closely related, species termed I. dumasi, which is supposedly named after Alexandre Dumas, but I have good reason to believe that this is a ruse. See here:
