Formicdubius Philips & Scholtz from South Africa, a junior synonym of Haroldius Boucomont, and a survey of the trichomes in the African species (Coleoptera, Scarabaeidae, Onthophagini)

Formicdubius Philips & Scholtz, 2000, a genus of South African scarab dung beetle, is synonymised with Haroldius Boucomont, 1914. All four African species of Haroldius, formerly in the genus Afroharoldius Janssens, possess trichomes. Trichome location and degree of development in the African species are discussed. The first record of Haroldius modestus Janssens from Malawi is given.
