Tetraconodont suids are in general rather poorly represented in Southern Africa, except at Langebaanweg, Cape Province and the Chiwondo Beds, Malawi. We here describe material from two localities in Namibia and one in South Africa in order to fill out the fossil record of this subfamily of artiodactyls in the subcontinent. The oldest specimens (Nyanzachoerus sp. cf jaegeri) are from Kaukausib Fontein, Namibia (ca 4-6 Ma), the next oldest (Gerontochoerus koobiforaensis) are from Brad Pit 'A', Bolt's Farm, South Africa (ca 3.7 Ma) and the youngest (Gerontochoerus scotti) are from Ekuma Rhino Site, northern Namibia (ca 3.2 Ma).
