Previously known species of Tritogenia Kinberg, 1867 from Natal are listed (benhami, crassa, curta, grisea, howickiana, karkloofia, morosa, mucosa, shawi, sulcata). Microchaetus zululensis Beddard, 1907 is transferred to Tritogenia; new data are provided for melmothana (Michaelsen, 1928), confirming placement in Tritogenia; the new species ngomensis is descriptionbed. New species: Microchaetus - mkuzi, vernoni, zaloumisi; Proandricus - babanango, bulwerensis, entumeni, jasoni, thornvillensis. New synonym: Microchaetus ivari Michaelsen, 1907 = Proandricus gracilis (Michaelsen, 1907). Keys to all South African species, for all three genera, are provided.
