The genus Kuwanimyia Townsend, before known only from one East Asian species (K. conspersa Townsend) is reviewed. Three new Afrotropical species, K. afra sp. nov., K. atra sp. nov. and K. capensis sp. nov. [the last one a parasitoid of Cossus tenebroides (Lepidoptera, Cossidae)] are described and illustrated. The generic limits of Kuwanimyia are reappraised to exclude Dolichocolon Brauer & Bergenstamm and Prosopodopsis Townsend. A key to the known species of Kuwanimyia is provided.
