Abstract: Callosides mafik sp. nov. from Ecuador (Napo) is described and its diagnostic
characters are illustrated. The new species clearly differs from all three
previously described for the genus in having short clavate macrosetation of the
dorsal surface, different configuration of tubercles of the dorsal surface and
the areolate-ocellate sculpture of elytra. The membranous distal part of the
mandible, a unique character within all Scarabaeoidea, is discussed.
