BIODONTOCNEMA BRUNNEA New Genus and New Species from South Africa (Coleoptera: Chrysomelidae: Alticinae)

Abstract Biodontocnema brunnea, a new genus and new species of flea beetle (Chrysomelidae: Alticinae) from South Africa is described. This new genus is close to Chaetocnema Stephens, 1831 but it is easily distinguishable mainly by the bidentate apex of its external, dorsal margin of hind tibiae (unidentate in Chaetocnema). Line drawings of male and female genitalia, and SEM photographs of particular morphological aspects of B. brunnea are provided.
