Diagnosis. Female distinguished by the ovoid, diverging spermathecae (Figs 16 H , I ) and PA of the epigynum that are as sclerotized as the AL (Figs 8 E , 16 G ). Male unknown. Description. Carapace orange-yellow, lighter posteriorly with smooth texture (Fig. 18 C ). Sternum dusky pale yellow (Fig. 18 D ). Chelicerae orange, with five promarginal teeth, two retromarginal teeth. Legs brown basally, leg I and II orange distally, posterior legs pale yellow distally. Abdomen medium gray dorsally with light dorsolateral patches (Fig. 18 C ). (Most setae lost on specimens so these data are not reported here.) Epigynum. Subpentagonal, MP/PL complex approximately 1/4 length of epigynum, parallel sided with grooves converging posteriorly, extending only slightly posterior from AL (Figs 8 E , 16 G ). PA sclerotized, undifferentiated from rest of epigynum. Female macrosetae: Leg I: femur d1, tibia v2-2, metatarsus v2-2 -2; leg II: femur d1, tibia v1, metatarsus v2-2; leg III: femur d1, tibia v1, metatarsus v1-3; leg IV: femur d1, metatarsus v1-1 -3. Holotype female (AcAT 88/29): Total length 3.6, carapace 1.44 long, 0.97 wide, 0.38 high, sternum 0.91 long, 0.50 wide. Leg measurements:

Distribution . Known from Western Cape Province, South Africa (Fig. 21). Remarks. Dippenaar-Schoeman (1989) reported the absence of a cribellum in this species. Indeed, no cribellum is obvious in the somewhat degraded type series specimens, although there is evidence of a broad lobe that could be a cribellum or wide colulus. In the holotype , most setae are missing from the legs, including the calamistrum region; in the juvenile paratype , both legs IV are broken near the tibia-metatarsus joint. Other specimens (i.e., those from Winterhoek, South Africa; B 2853, SAM-ENW-B002853), have a well developed cribellum (Fig. 8 F ) and calamistrum.
