The marleyi species­group To this group, characterised by spermathecal pores occurring in only two intersegmental furrows 11/12 and 12/13, and with variably thickened four septa 4/5 5/6 6/7 7/8, or with three septa 5/6 7/8 8/9 thickened, are assigned three species: marleyi Michaelsen, 1928 , alatus Plisko, 1996 , and armstrongi Plisko, 2002 . P. marleyi and alatus were collected in Melmoth area. P . armstrongi is known from the Mount Currie Nature Reserve, being an extension of the south­eastern Drakensberg foothills. No new material for all three species is presently available. Species distribution in KZN is shown in Fig. 7 .
