Purcelliana problematica Cooke, 1964: 282   , figs 47, 52, 64 (Holotype male from Prince Albert   GoogleMaps , Western Cape [33°13’36.57”S 22°2’8.57”E], South Africa, deposited in SAMC 3916 View Materials , examined).

Remarks. As observed by Cooke (1964), the holotype is poorly preserved, but it is possible to identify the diagnostic characters for the genus in the specimen. In addition, obtaining additional material allowed us to complement the description of the genus, as well as that of P. problematica   .

Diagnosis. Males of Purcelliana problematica   resemble those of P. cederbergensis   sp. nov. by the male palp with the embolus mostly straight ( Figs 31A, B View FIGURE 31 ) and a strong, laterally protruding dRTA, but are distinguished by the presence of a median, distally rounded tegular projection (absent in P. cederbergensis   sp. nov.) and by the embolus slender and tapering (laminar and robust in P. cederbergensis   sp. nov. Figs 31E View FIGURE 31 ). Females are unknown.

Description. Male (NCA 2008/679). Carapace and legs pale yellow, abdomen gray ( Fig. 26E View FIGURE 26 ). Total length: 2.42. Carapace 1.05 long, 0.90 wide; Abdomen 1.37 long, 0.72 wide; Sternum 0.77 long, 0.63 wide; Spinnerets: ALS 0.17 long, 0.13 wide. Eye diameters: AME 0.05, ALE 0.04, PME 0.07, PLE 0.09; interdistances: AME–AME 0.05, PME–PME 0.04. Chelicerae 0.44 long. Leg measurements: I: 3.84 (1.04, 0.59, 0.90, 0.74, 0.58); II: 2.83 (0.80, 0.44, 0.59, 0.54, 0.46); III: 2.38 (0.65, 0.38, 0.45, 0.46, 0.44); IV: 3.46 (0.94, 0.50, 0.80, 0.70, 0.53). Palp: vRTA truncated, smaller than dRTA, latter with tip curved ventrally; conductor hyaline, laminar, distally widened ( Figs 31 View FIGURE 31 A–C).

Female. Unknown.

Distribution. South Africa ( Fig. 34 View FIGURE 34 ).

Material examined. South Africa: Western Cape, Anysberg Nature Reserve , 33°31′48″S 20°45′36″E, 1 male, 24 September 2005, C. Haddad & R. Lyle leg. ( NCA 2008 /679) GoogleMaps   .
