D i a g n o s i s: The extraordinarily rough sculpturing on the surface of this beetle will distinguish it from congeners. The genus Madoniella PIC was revised during 2011 (OPITZ 2011b).

D i s t r i b u t i o n: This species is known from México. E t y m o l o g y: The trivial name, aspera, is a Latin adjective with a meaning of "rough"; with reference to the rough surface of the dorsum of this beetle.
