Figs 26 View FIGURE 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. GoogleMaps   , deposited in SMN 41144 View Materials . 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 View Materials ) GoogleMaps   .

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 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 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 View FIGURE 32 ); 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 View FIGURE 30 , 32E View FIGURE 32 ). Both males and females are markedly larger that those of P. khabus   .

Description. Male ( SMN 41144 View Materials ). Legs orange and abdomen pale yellow ( Figs 26A, B View FIGURE 26 ). Total length: 3.30.

Leg measurements: I: 6.03 (1.64, 1.08, 1.34, 1.06, 0.91); II: 4.44 (1.25, 0.73, 0.92, 0.83, 0.70); III: 3.84 (1.09, 0.64, 0.78, 0.80, 0.53); IV: 5.58 (1.47, 0.98, 1.28, 1.00, 0.84).

Variation. Total length (4 males): 2.40–3.30; (3 females): 3.28–3.76.
