Abstract

The Afrotropical scarab beetle genus Cerhomalus Quedenfeldt, 1884 (Coleoptera: Scarabaeidae) is revised. Two new species are described: C. quedenfeldti sp. nov. and C. petrovitzi sp. nov. A new combination, Cerhomalus absconditus (Petrovitz, 1971) comb. nov., is established. The genus occurs in Central and West Africa with the majority of records from the Congo Basin. Keys, descriptions, illustrations of habitus and male genitalia, and distributional record map are given
