Type material. Holotype: male, SOUTH AFRICA: MPUMALANGA: Mariepskop State Forest, Drakensberg, 1.8km N Mariepskop Chalets (Ranger Station), moist montane indigenous forest, 14 Oct. 1999, coll. D. Ubick & S. Prinsloo (UBC-SEM AR00199, CAS). Paratypes: 1 female, same data as holotype (UBC-SEM AR00200, CAS); 1 male and 3 females, same data as holotype ( CAS).

Etymology. The specific epithet is a patronym in honor of Dr. W. Wesolowska, who has made great contributions in studies of jumping spiders from Africa.

Diagnosis. Differs from other Thyenula   species by the combination of following characters: male palp with wide proximal tegular lobe, relatively small embolic disc and thick embolus ( Figs 97–98 View FIGURES 95 – 101 ); vulva with wide copulatory duct and round spermatheca ( Fig. 101 View FIGURES 95 – 101 ).

Description. Male (holotype, UBC-SEM AR00199). Carapace length 1.5; abdomen length 1.6. Chelicera: with two promarginal teeth and one retromarginal tooth. Palp ( Figs 97–98 View FIGURES 95 – 101 ): yellow brown. Embolus long and coiled for more than half a circle; retrolateral sperm duct loop very wide almost occupying full width of bulb; proximal tegular lobe relatively large; retrolateral tibial apophysis long and finger-like. First leg with three pairs of ventral macrosetae on tibia and two pairs of ventral macrosetae on metatarsus. Measurements of legs: I 3.5, II 2.5, III 2.6, IV 3.2. Color in alcohol ( Fig. 95 View FIGURES 95 – 101 ): carapace with eye area dark brown, posterior part dark yellow brown; dorsal abdomen gray brown to dark brown, with yellowish brown speckles and markings; first pair of legs dark brown, other legs light yellow brown with brown annuli.

Female (paratype, UBC-SEM AR00200). Carapace length 1.8 (variation: 1.5–1.8, n= 4); abdomen length 2.3. Chelicera ( Fig. 99 View FIGURES 95 – 101 ): with two promarginal teeth and one retromarginal tooth. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 3.1, II 2.6, III 3.0, IV 3.5. Epigynum ( Fig. 100 View FIGURES 95 – 101 ): window large with a narrow median septum; opening to copulatory duct close to anterior margin of window. Vulva ( Fig. 101 View FIGURES 95 – 101 ): copulatory duct relatively wide; spermatheca almost spherical. Color in alcohol ( Fig. 96 View FIGURES 95 – 101 ): similar to that of male.
