Frolov, A.V., Akhmetova, L.A. & Scholtz, C.H. 2008. Revision of the obligate mushroom-feeding African “dung beetle”genus Coptorhina Hope (Coleoptera: Scarabaeidae: Scarabaeinae). Journal of Natural History, 42, 1477-1508.
The African genus Coptorhina Hope is revised. Nine new synonymies are established which reduces the number of valid names from 15 to six. One new species is also described. The name changes are the following: C. subaenea Janssens, C. bicolor Ancey, C. pygmaea Balthasar, and C. saganicola Müller are considered junior synonyms of C. nitidipennis Boheman; C. africana Hope, C. vicina Péringuey, C. obtusicornis Boheman, C. punctata Ferreira and C. optata Péringuey are considered junior synonyms of C. klugii Hope. The new species, C. excavata sp. n., is described from southern Africa. A key to the species and notes on biology are given.
