The sclerodactylid subfamily Sclerodactylinae is restricted to include only those forms with a short, compact, tubular calcareous ring and a new subfamily Sclerothyoninae is diagnosed to accommodate two new southern African monotypic genera Sclerothyone and Temparena, with compact but non-tubular calcareous rings. The new genera are erected respectively for Ludwig and Heding's (1935) Cucumaria? velligera and C.? chuni, formerly classified in Pentamera. This brings the total number of sclerodactylid holothurians known from southern Africa to six genera and seven species. All taxa are diagnosed and/or descriptionbed, a key is provided for all southern African species and their local distributions are mapped.
