Material examined: KwaZulu­Natal: Wagendrift Nature Reserve: NMSA /Olig.03354 (29º02'31"S: 29º50'13"E) in top layers of soil and among grass roots in summit grassland, 27 February 2001, 12 juv, [2 with tubercula pubertatis and slightly marked clitellum] AJA, PN; NMSA /Olig.03451 (29º02'32"S: 29º50'15"E) in top layer of soil above rocks, medium­high grass and small shrubs, 4 May 2001, 14 cl, AJA, BK. Eastwolds (30º00'S: 29º55'E) area, ca. 30 km north­west of Ixpopo along the road to Bulwer, from fallow ground: NMSA /Olig.00720, 1 mature, autotomised into 4 pieces; NMSA / Olig.00730, 12 cl abscised anterior parts + 10 juv + 10 abscised juv; all collected 29 January 1991 by JDP; ca. 25 km north­west of Ixopo along the road to Bulwer, from ditch near road, NMSA /Olig.00657, 1 with partly absorbed clitellum and tubercula pubertatis, in quiescent phase, 5 June 1990, JDP, A. Zicsi. Remarks:The species is related to ivari and jasoni. Recently studied material differs slightly from the type descriptions.
