Figs 26 A–C, 27A–F, 28A–F, 29A–F, 30A–F, 32A–G 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 . Description. Male (SMN 41144). Legs orange and abdomen pale yellow ( Figs 26A, B ). Total length: 3.30.
