Description of a new monospecific genus of South African Trichiina, with a key to the related genera (Coleoptera: Scarabaeidae)

A new monospecific genus, Pseudostegopterus gen. nov., endemic to the northwestern region of South Africa, is erected. The type species is described as Pseudospegopterus melonthinoides sp. nov. and is currently known only from male specimens. A provisional dichotomic key of the African Trichiina genera is also provided, in order to facilitate the identification of male specimens to the genus level.
