Three new Ceramonema species, one new Dasynemoides species and one new Pterygonema species are described from South Africa. Ceramonema algoensis sp. nov. is characterised by more than 300 annules and the elongated cephalic capsule with an elevated lip region; C. africana sp. nov. by an elongated cloacal annule and a long cephalic capsule; and C. kromensis sp. nov. by the absence of vascuolisation and a relatively short cephalic capsule. Dasynemoides tenuis sp. nov. can be distinguished from all other known species of the genus by its slender body (a=118) and the large number of body annules (690). Pterygonema papenkuili sp. nov. is characterised by the shape of the spicules, which have a spine-like structure, and a large and rectangular gubernaculum.
