Figs 50–63 View Figs 50–54 View Figs 55–63 , 120 View Fig

Etymology:This new species is named for Ansie Dippenaar-Schoeman, for her important and manifold contributions to arachnological research in Africa. Moreover, she is a wonderful person; noun (name) in apposition.

Diagnosis: Medium-sized spiders of the African clade with body length 13 to 13.2 mm in males. Cymbium narrow, as wide as tibia, widest point in proximal half ( Figs 50 View Figs 50–54 , 58 View Figs 55–63 ). Embolus stout with concave distal part and subdistal round extension ( Fig. 52 View Figs 50–54 ).

Description:

Male (holotype, PJ 2281).

DS length 6.3, width 5.3, anterior width 2.9, OS length 6.7, width 4.0. Eyes ( Fig. 54 View Figs 50–54 ): AME 0.40, ALE 0.32, PME 0.26, PLE 0.34,AME–AME 0.16, AME–ALE 0.05, PME– PME 0.50, PME–PLE 0.30, AME–PME 0.30, ALE–PLE 0.30, clypeus height at AME 0.53, at ALE 0.61. Spination: palp: 131, 001, 2121 (1010); legs: femur I–III 323, IV 322; patella I–IV 101; tibia I–IV 2226; metatarsus I–III 3034, IV 3037. All metatarsi with sparse scopula; leg IV ventrally with double row of bristles along entire length and additional rows in proximal half. Tarsus IV ventrally with 6–7 claw slit sensilla (sensu RamÍrez 2014) in distal transverse suture. Leg formula: 431. Measurements of palp and legs: palp 8.7 (3.0, 1.2, 1.9, -, 2.6), leg I 29.7 (7.5, 3.0, 7.8, 7.9, 3.5), leg II - (8.7, 3.2, 9.0, 8.9, -), leg III 30.4 (8.2, 3.0, 7.9, 8.0, 3.3), leg IV 32.2 (9.2, 2.7, 8.5, 8.5, 3.3). Cheliceral furrow without denticles; promargin of chelicerae with 2 teeth, retromargin with 3 teeth; with 1 bristle at fang base ( Fig. 53 View Figs 50–54 ). Gnathocoxae without serrula ( Figs 60, 63 View Figs 55–63 ). Palp as in diagnosis ( Figs 50–52 View Figs 50–54 , 58–59 View Figs 55–63 ): Cymbium distally with dense brush of strong bristles, with weakly developed retrolateral bulge. Embolus arising at 1 o’clock from tegulum, distal tip pointed with spermophor opening distally, proximal part with dorsal extension. Conductor arising at 12 to 12.30 o’clock from tegulum, distad. Spermophor running prolaterally submarginally, on retrolateral side slightly S-shaped. RTA short, extending barely beyond the cymbial “shoulder”, with one distal tip, sharply pointed and disto-mediad. Prolateral tibial spines forming with additional long setae on tibia one conspicuous row, another row formed by long setae on ventral tibia ( Figs 50 View Figs 50–54 , 58 View Figs 55–63 ). Coloration ( Figs 55–57 View Figs 55–63 ):Yellowish brown without distinct pattern. DS with longitudinal fovea. DS with white hairs around eyes, along DS margins and around fovea, in central part with brown hairs. Sternum, coxae, legs, gnathocoxae and labium light yellow, the two latter with white distal half and lip, respectively. OS dorsally with longer light and brown hairs, ventrally only with light hairs, except for part in front of spinnerets and spinnerets partially with long dark hairs.

Female. Unknown. The subadult female exhibits a pre-epigyne and pre-vulva that must not be confused with an epigyne and vulva of an adult female.

Variation: Male (n=1): DS length 6.1. OS length 7.1. Spination: Palpal patella 002, tarsus 0000 (only with bristles, without spines); tibia I 3236, II 3236/2226. Chelicerae with 3 posterior teeth, with proximal two fused at their base.
