Etymology: This new species is named for Rudy Jocqué, for his important and manifold contributions to arachnological research in Africa; moreover, he inspired many arachnologists through his (sometimes unconventional) thoughts and ideas; noun (name) in apposition.

Diagnosis: Small Sparassidae with body length of 8.1 mm in males. Cymbium voluminous, much wider than tibia, leaving bulbus genitalis as small oval in the centre ( Figs 64–65 View Figs 64–69 , 73–74 View Figs 70–77 ). Embolus stout, sickle-shaped ( Fig. 66 View Figs 64–69 ). Female unknown.

Description:

Male (holotype, PJ 3537).

DS length 3.7, width 3.2, anterior width 1.8, OS length 4.4., width 2.6. Eyes ( Fig. 68 View Figs 64–69 ): AME 0.31, ALE 0.29, PME 0.19, PLE 0.30,AME–AME 0.09, AME–ALE 0.00, PME– PME 0.32, PME–PLE 0.23, AME–PME 0.23, ALE–PLE 0.20, clypeus height at AME 0.30, at ALE 0.35. Spination: palp: 131, 001, 2111; legs: femur I 323, II 323(4), III 323, IV 322; patella I–II, III 001, IV 101; tibia I 2226, II 1126, III–IV 2226; metatarsus I–II 3034, III 3024, IV 3037. All metatarsi with sparse scopula; legs III and IV with double row of bristles along entire length, continued with high number of bristles on tarsus in leg IV. Tarsi with scopula well developed, tarsus III ventrally with 5 claw slit sensilla (sensu RamÍrez 2014) in distal transverse suture. Leg formula: 2431. Measurements of palp and legs: palp 5.9 (1.9, 0.9, 1.2, -, 1.9), leg I 19.7 (5.0, 2.0, 5.4, 5.1, 2.2), leg II 21.5 (5.4, 2.0, 6.1, 5.6, 2.4), leg III 20.2 (5.3, 1.9, 5.6, 5.3, 2.1), leg IV 21.1 (5.7, 1.7, 5.9, 5.5, 2.3). Cheliceral furrow without denticles; promargin of chelicerae with 2 teeth, retromargin with 3 separated teeth; with 2 bristles at fang base. Both gnathocoxae without serrula. Metatarsal stopper (sensu RamÍrez 2014) with median hook and lateral projections weakly developed, median hook slightly extending beyond lateral projections ( Fig. 69 View Figs 64–69 ). Palp as in diagnosis ( Figs 64–67 View Figs 64–69 , 73–75 View Figs 70–77 ): Cymbium distally with dense brush of strong bristles. Bulbus genitalis small, half the length or width of cymbium. Embolus arising at 12.30 o’clock from tegulum, distal part sickle-shaped, proximal part with dorsal extension, with spermophor opening subdistally on ventral side. Conductor arising at 12.30 o’clock from tegulum, prolaterodistad. Spermophor running prolaterally submarginally, on retrolateral side slightly S-shaped. RTA short, extending barely beyond the cymbial “shoulder”, with two distal tips, the inner small one sharply pointed and mediad, the outer larger, blunt. Prolateral tibial spines forming with additional long setae on tibia and cymbium one conspicuous row ( Fig. 64 View Figs 64–69 ), another row formed by long setae on ventral tibia ( Fig. 65 View Figs 64–69 ).

Coloration ( Figs 70–72 View Figs 70–77 ): Yellowish brown without pattern. DS with longitudinal fovea; white hairs present along DS margins. Sternum, legs, gnathocoxae and labium pale yellowish, latter two with distal white half and lip, respectively. Opisthosoma dorsally with light and dark setae, heart patch without dark setae; ventrally light, epiandrous spigots in two patches; spinnerets ventrally and ventral area anterior of spinnerets with dark setae.

Female. Unknown.

Holotype ♂ (PJ 3537): NAMIBIA: Erongo: E Brandberg, Copper Valley , 21°05''S 14°14'E, 496 m, ground at night, E. Griffin leg., 27.x.1999, SD 1209 ( SMN 44496 ).
