Additional material examined. 1 ♀ ( UPSA): “ Rietpoort / S 30.97729° E 18.00026° / 30.viii.2004 / C. Deschodt & M. Deschodt leg” .

Size range. Males length: 11.8–13.2 mm, width: 8.5–9.0 mm; females length: 10.7–12.5 mm, width: 8.6–9.6 mm.

Differential diagnosis. Resemble M. tortuosus new species in having pronotum with elongated punctures ( Fig. 64 ) and M. mutilans in the general body features, however, it can be distinguished from the former by having impunctate lateral borders of the pronotum and from the later by having rather undulate surface of elytra and also by having very long lateral process of internal sac of aedeagus ( Fig. 27 )

Habitat and distribution. Rietpoort and Komaggas are two localities in Namaqualand region ( Fig. 2). The area is dry and hot; characterised by low annual rainfall and a wide distribution of succulent vegetation.
