Diagnosis. The male palp of this species is similar to that in T. munda ( Peckham & Peckham, 1903)  , but has a clearly wider proximal part of the embolus. The female epigyne is similar to that in T. juvenca Simon, 1902  , but differs in having two-chambered spermathecae (single in T. juvenca  ). The latter species is also clearly larger and uniformly yellow.

Description. Measurements (male/female). Cephalothorax: length 1.9/2.0, width 1.4/1.4, height 0.9/0.9. Abdomen: length 1.8/2.2, width 1.3/1.6. Eye field: length 0.9/0.8, anterior width 1.3/1.2, posterior width 1.2/1.1.

Male. General appearance as in Fig. 241View FIGURES 241–244. Carapace brown with darker ocular area, some white hairs on thoracic part. Sternum yellowish brown. Some brown bristles near eyes, scarce white hairs on slopes. “Cheeks”, clypeus and chelicerae brown, cheliceral dentition as in Fig. 242View FIGURES 241–244. Abdomen greyish brown with yellow spots and markings ( Fig. 241View FIGURES 241–244). Venter light with two brownish streaks. Book-lung covers and spinnerets brown. Femora, patellae and tibiae of legs I dark brown, metatarsi yellow with brown rings at base and tip, tarsi yellow. Femora of legs II brown, with yellow stripe dorsally and yellow patch distally on ventral surface. Femora III and IV and other segments of legs II–IV yellow, with brown rings distally and proximally. Pedipalps yellow, only femora brown. Tibial apophysis long and thin, bulb with large proximal lobe, embolus long, relatively broader than in congeners, embolic spiral partially enveloped by bulb ( Fig. 243View FIGURES 241–244).

Female. Similar to male, slightly lighter in colour ( Fig. 245View FIGURES 245–249). Abdomen brownish with darker pattern composed of dense small spots, fused distally into a few chevrons. In some specimens femora of all legs black. Epigyne with small anterolateral depressions ( Figs 246, 248View FIGURES 245–249). Seminal ducts short, broad in initial part ( Figs 247, 249View FIGURES 245–249).

Distribution. Known from the Limpopo and Mpumalanga Provinces of South Africa.

Genus Yimbulunga  gen. nov.

Type species: Yimbulunga foordi Wesołowska, Azarkina & Russell-Smith  Diagnosis. The genus is distinctive in the stout body form, which is shorter and broader than in other Euophryinae  genera. They are small spiders, and the carapace is high, relatively short and wide, with a large eye field and convex posterior lateral eyes. The abdomen is small and rounded. The structure of the pedipalp is very similar to that in Euophrys  with a thin embolus, forming one coil in the basal spiral. Chelicerae with a fissident retromarginal tooth.

Etymology. The generic name is derived from the Zulu word meaning spherical and referring to the body form of the spider. Feminine in gender.

Composition. Single new species.

Distribution. Only known from South Africa.
