Macroderes dubius Péringuey, 1901: 301 ; Janssens 1939: 29; Ferreira 1969: 320; Frolov & Scholtz 2005: 392.

Type locality. Cape Colony (no exact locality) .

Type material examined. None. No indication of where the type was deposited in Péringuey’s original description.

Remarks. Unfortunately we could not locate the holotype of this species, but according to Péringuey’s (1901: 301) original description, body size is 11 mm in length and 7.5 mm in width and it resembles M. politulus in size, shape, head, and punctuation of the pronotum. Péringuey (1901) mentioned that this species differs from M. politulus by bearing a more convex and rounded pronotum without any observed excavation antero-laterally. In addition, the species has even elytral intervals covered by finer and shallower punctures than M. politulus , costate and punctate striae. He also observed an unusual elytral shape in the specimen he studied and attributed this to a malformation.
