The Afrotropical subgenus Phornus Paulian, 1948 of the genus Orphnus MacLeay, 1819 is revised and currently comprises six species. Four new species are described: Orphnus renaudi sp. nov., Orphnus valeriae sp. nov., Orphnus ferrierei sp. nov. and Orphnus parastrangulatus sp. nov. The subgenus is characterized by the coarse stridulatory field, sclerotized plate on the second abdominal sternite near plectrum, absence of the pronotal lateral processes in males, rounded apices of the parameres and endophallus without armature, although some of these characters differ in O. giganteus Paulian, 1948. Symphysocery is reported for the first time for members of the Orphninae. In O. giganteus, the majority of specimens have malformed antennomeres. Four of the six species of Phornus are brachypterous and all species except for O. giganteus are known only from males. A key to Phornus species and a map of their localities are provided.
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.
The scarab beetles of the subfamily Orphninae (Coleoptera: Scarabaeidae) from Sri Lanka are reviewed. Four species of the genus Orphnus Macleay, 1819, are recorded from the island: O. bicolor (Fabricius, 1801), O. parvus (Wiedemann, 1823), O. mysoriensis Westwood, 1845, and O. medvedevi sp. nov. Lectotypes are designated for the three former names. Synonymy of O. detegens Walker, 1859, and O. scitissimus Walker, 1859, is discussed. Keys, illustrations of habitus and male genitalia, and distributional record maps are given for all species.
