Tritogenia herbana Plisko, 1997

Tritogenia herbana Plisko, 1997: 257 .

Material examined: KwaZulu­Natal: NMSA / Olig.01251 Platberg (28º20'S: 29º59'E) Elandslaagte, Mawelawela Game Farm (Mr G. Mitchell Innes Farm) grassland, 7 December 1992,1 cl + 4 semi­mature, JDP, BRS .

Remarks: The external and internal characters are in accord with the original description (Plisko, 1997), although the genital glands were observed only in segment 12, a variation possibly related to the degree of maturity. Known from KZN, and from the north­eastern Drakensberg escarpment in Mpumalanga province. Present record extends the known range of species into central KZN, and suggests much broader occurrence than is usually observed in the other species of this genus. The collection sites in KZN are shown in Fig. 14 .
