Paratypes: together with holotype, 2 females; SOUTH AFRICA, Cape Town, Table Mountain National Park, Cecilia , Rooikat Ravine , 33°59'S: 18°24'E, afrotemperate forest, sugar-baited ant trap, 1 male, 21 February 2009, leg. C. Uys ( NCA 2011 /898); same locality, Tokai South, 34°04'S: 18°24'E, afrotemperate forest, sugar-baited ant trap, 1 male, 19 January 2009, leg. C. Uys ( NCA 2011 /897); same data, 1 female ( NCA 2011 /896) .

Diagnosis. This species is characterized by the light coloration of the abdomen, with only some dark markings at the lateral margins. The structure of the male pedipalp slightly resembles that in R. bellus , but the tibia is longer, the proximal lobe of bulb very is short, the embolus is shorter, and the tibial apophysis is pointed., but the seminal ducts are short and broad.

Etymology. The specific name is Latin and refers to the abdominal pattern.

Description. Measurements (male/female). Cephalothorax: length 2.6/2.5–2.8, width 2.0/2.0–2.1, height 0.9/ 0.9. Abdomen: length 2.3/3.1–3.2, width 1.6/2.2–2.3. Eye field: length 1.2/1.2, anterior width 1.7/1.7–1.8, posterior width 1.6/1.6–1.7.

Male. General appearance as in Fig. 120 . Carapace oval, moderately high, widest behind midpoint, sloped posteriorly. Eye field short, distance between anterior lateral eyes slightly larger than between posterior laterals. Thoracic part brown, lighter medially, eye field dark brown. Brown and colourless hairs cover carapace, long brown bristles near eyes. Clypeus low, brown. Chelicerae dark, with two promarginal teeth and single tooth on retromargin. Labium, endites and sternum yellowish orange. Abdomen oval, whitish yellow with grey markings laterally, scarce long brown bristles on abdominal dorsum. Venter and spinnerets light. Legs yellow with brown hairs and light spines. Tibia I with three pairs of ventral spines, metatarsus I with two pairs. Pedipalps yellow, clothed in brown hairs. Tibial apophysis curving slightly in ventral view. Bulb rounded, with small proximal lobe, spermophore meandering, embolus thin, form a loop on tip of bulb, with additional terminal apophysis ( Fig. 122 ).

Female. Slightly larger than male, similarly coloured. Grey hairs on eye field anteriorly and on thoracic slopes. Abdomen light with greyish marks laterally, but these marks lighter and more numerous than in male. Epigyne with two rounded anterior depressions divided by median ridge ( Fig. 124 ). Internal structures as in Fig. 125 , seminal ducts wide.

Distribution. Known from the Western Cape Province of South Africa.
