Afractinolaimus Andrassy, 1970 is regarded as valid, its diagnosis slightly emended, and the following species transferred to it: Paractinolaimus capensis, P. minor, P. zairensis and P. magaliesmontanus. The name of the type species thus becomes A. magaliesmontanus, since it has priority and is regarded as conspecific with A. noblei, the designated type. Additional biometrical data and distribution records are presented for A. magaliesmontanus. A. zairensis is reported from South Africa. Information is given for several populations of P. microdentatus .. Two new species of Neoactinolaimus are descriptionbed: N. brachydorus n. sp. is characterized by an exceptionally short and stout odontostyle, and N. barbieri n. sp. is distinguished from the closely related N. vaalensis by a thicker cuticle, more prominently set-off head, corrugated vestibule, longer oesophagus and several other minor morphological differences. Egtitus Thorne, 1967 is regarded as valid, and the following combination proposed: Egtitus zealandicus (Clark, 1963) n. comb. (synonym: Actinolaimus zealandicus).
