The microchaetid species with spermathecal pores anterior to the testicular segment, intrasegmental or intersegmental, in 8/9, 9, or 9/10 and 10/11, were studied, These characters were observed in species of three genera: in proandric Proandricus (8 spp.), and holandric Geogenia (3 spp.) and Tritogenia (1 sp.). Some irregularities in setal arrangement, seldom observed in South African microchaetids but occurring in these proandric species, are considered in the lesothoensis species-group, Unusual for the South African microchaetids, although known in the South American glosscoscolecids, the locations of the spermathecae and their pores, a discrepancy in the arrangement of setae, and the species' geographical distribution all suggest a relationship with the Glossoscolecidae and a presumed Gondwanan origin. The distribution of the species in Gondwana ancestral to the Drakensberg is discussed. Two holandric species with spermathecae and their pores in the testicular and post-testicular segments are compared.
