Type material. Male holotype from Namibia, Kamaseb, Etosha National Park, 19°04’S 16°41’E, 26 March– 4 May 1988, E. Griffin leg., deposited in SMN 41144. Paratypes: 2 males with same data as holotype; 2 females from same locality as holotype, 8 August– 14 September 1987, E. Griffin leg., (SMN 40697).
Etymology. The specific name refers to the type locality, noun in apposition.
Diagnosis. Purcelliana kamaseb sp. nov. resembles P. khabus sp. nov. in having the carapace reddish-brown and strongly rugose (Figs 26A, B), and by the male palp with the embolus curved retrolaterally (Figs 32B, 33B). The males are distinguished by the palps with vRTA pointed in ventral view and truncate in retrolateral view (rounded in P. khabus) and by the dRTA bent ventrally (bent dorsally in P. khabus) (Figs 32B, D); females are distinguished by the epigyne with diverging V-shaped copulatory openings (converging in P. khabus) and by the posterior-median depression with longitudinal grooves (absent in P. khabus) (Figs 30E, 32E). Both males and females are markedly larger that those of P. khabus.
