A large part of the studied material was deposited in the ZMUHand some specimens in the BMNH. Two paratypeshave been left in the NMSA, numbered MN309 and MN446, and are currently accessioned under the numbers NMSA/Olig.00272, and NMSA/Olig.00273 (Plisko 2006). In the same year Michaelsen (1913 b: 547) described a microchaetid, giving the name ‘  Microchaetus warreni n. sp.’, depositing three typespecimens in the ZMUH(#7765), and one paratypein the NMSAcollection (present accession number NMSA/Olig.00271). For many years, the material of both species has not been examined, and this misled Reynolds and Cook (1976: 189)to state that  Microchaetus warreniwas a synonym of  Chilota( Parachilota) warreni. Plisko (1991)has clarified the taxonomic status of both species.   P. warrenibelongs to a group of species with spermathecal multilobate diverticula. The multilobes are attached to the front face of the spermathecal duct and are not fused posteriorly ( Fig. 14). It is similar to  P. uysae, but the species differ in the shape of the spermathecae and the commencement of the intestine.  Figs 13, 14. Spermathecae of  Parachilotaspecieswith multilobate diverticulum, 500×: (13)  P. uysae sp. n., holotype; (14)  P. warreni(Michaelsen, 1913), spermathecae from ventral side of body. Abbreviations:A – ampulla, D – spermathecal duct, MDv – multilobate diverticulum, MDvl – left part of multilobate diverticulum of anterior spermathecae, MDvm – medial part of multilobate diverticulum of posterior spermathecae, MDvr – right part of multilobate diverticulum of anterior spermatheca. Biological notes and distribution:The species is known from distinct habitats, preferring moist or wet biotopes. It appears at distantly separated sites in the Drakensberg foothills in KZN, extending its range to the KZN midlands, and to Auckland Forest in the Eastern Cape.Although our knowledge of its distribution is still limited, it may be noted that its fragmented appearance is probably affected by anthropogenic changes to the environment.
