Type material. Male holotype from Namibia, Keetmanshoop , Khabus 146, 26°17’S 18°14’E, 7 December 1987 – 17 January 1988, N. Olivier leg., deposited in SMN 40749 View Materials . GoogleMaps   Paratypes: 1 male from same locality as holotype, 28°18’S 18°13’E, 14 April 1988, N. Olivier leg., ( SMN 42020 View Materials ) GoogleMaps   ; 1 female from Namibia, Mariental , Berseba 170, 25°12’S 18°03’E, 7–29 November 1992, E. Marais leg., ( SMN 42879 View Materials ) GoogleMaps   .

Etymology. The specific name refers to the type locality, noun in apposition.

Diagnosis. Purcelliana khabus   sp. nov. resembles P. kamaseb   sp. nov. in having the carapace reddish-brown and strongly rugose ( Figs 26A, B View FIGURE 26 ), and by the male palp with the embolus curved retrolaterally ( Figs 32B View FIGURE 32 , 33B View FIGURE 33 ). The males are distinguished by the palps with vRTA rounded in ventral view (pointed in P. kamaseb   sp. nov.) and by the dRTA bent dorsally (ventrally in P. kamaseb   sp. nov.) ( Figs 33B, C View FIGURE 33 ); females are distinguished from P. kamaseb   by the epigyne with V-shaped copulatory openings converging (diverging in P. kamaseb   sp. nov.) and by the posterior-median depression without longitudinal grooves (present in P. kamaseb   sp. nov.) ( Fig. 33D View FIGURE 33 ). Both males and females are markedly smaller than those of P. kamaseb   sp. nov.
