Type material. Holotype: ♀ (with 2 ♀ paratypes), Grahamstown [Eastern Cape], South Africa, 33°19'S 26°32'E, 500 m, 1 January 1980, in riverine bush from soil surface, P. Croeser, P. Hawkes ( AcAT 87/249, NCA).GoogleMaps  Paratypes: ♀, same data as holotype ( AcAT 87/249a, NCA)GoogleMaps  ; ♀, same data as holotype ( AcAT 87/ 249b, NCA)GoogleMaps  .

Diagnosis. Female distinguished by the narrow connection between the AL and the MP, which then becomes a wide plate with convex lateral margins (Fig. 16 E). Male unknown.

Description. Carapace red-brown, lighter posteriorly with smooth texture, with sparse fine black setae and broad white setae mostly at margin and fovea region (Fig. 18 A). Sternum dusky pale yellow (Fig. 18 B). Chelicerae red-brown, with six promarginal teeth, three retromarginal teeth; with fine black setae only. Legs brown basally, anterior legs red-brown distally, posterior legs pale yellow distally. Abdomen medium gray dorsally without light dorsolateral patches, covered by fine black setae, broad white setae around margin (Fig. 18 A).

Epigynum. Subpentagonal, clearly differentiated from surrounding cuticle. AL a half oval, connected to MP by narrow waist; MP a wide plate with convex lateral margins; MP/PL complex approximately 1/3 length of epigynum, much wider posteriorly than anteriorly. PA only marginally less sclerotized than the rest of the epigynum, separated from AL by groove (Fig. 16 E).

Female macrosetae: Leg I: femur d1, tibia v1-2, metatarsus v1-2 -2; leg II: femur d1, tibia v1, metatarsus v1-2; leg III: femur d1, tibia v1, metatarsus v1-2; leg IV: femur d1, metatarsus v1-2; tarsus r1.

Paratype female (AcAT 87/249): Total length 5.0, carapace 2.13 long, 1.59 wide, 0.53 high, sternum 1.25 long, 0.72 wide. Leg measurements:
