Breviclypeus, a new South African Trichiina genus (Coleoptera: Scarabaeidae, Cetoniinae)

A new genus, Breviclypeus gen. nov., endemic to South Africa, is erected. The type species is here designated to be Agenius rufipennis Gory & Percheron 1833 (comb. nov.). A second species, Campulipus plagosus (Pèringuey, 1885) is recognized to belong into this new genus (comb. nov.). Consequently, the genus Campulipus Kirby, 1827 is now represented by three species only, Campulipus limbatus (Olivier, 1789), Campulipus clavus (Schaum, 1844) and Campulipus suturalis (Waterhouse, 1885). A fourth taxon, Agenius nobilis J. Thomson, 1878 is here transferred to Campulipus (comb. nov.) and synonymized with C. limbatus (syn. nov.) The two genera not only exhibit key morphological differences, but also occupy different habitats and diverge substantially in their ecology. An updated key of the genera of South African Trichiina is also provided. A separate key is provided for the genus Breviclypeus.
