Diagnosis. This species is distinguished by the form of its genital organs. The male has a bulb divided into two longitudinal lobes, a ribbon-like embolus and short pointed tibial apophysis ( Fig. 150 ). The epigyne has two rounded depressions in anterior half and a double pocket at epigastric furrow ( Fig. 156 ).

Redescription. Male. Measurements. Cephalothorax: length 2.2–2.4, width 1.7–1.9, height 1.0–1.1. Abdomen: length 2.4–2.7, width 1.5–1.9, height 0.9–1.0. Eye field: length 0.9–1.0, anterior width 1.3–1.4, posterior width 1.2– 1.3. General appearance as in Figs 144–146 . Carapace oval, slightly wider posteriorly, high in cephalic part, brown, eyes surrounded by black rings (except anterior medians) and encircled by whitish short hairs, yellowish median band on thoracic part. White hairs form light streaks on lateral sides of carapace, sparse protruding brown bristles on dorsum, dense colourless recumbent hairs on eye field, whitish between anterior eyes. Light hairs on clypeus ( Fig. 146 ) and dorsal surfaces of chelicerae. Chelicera with large tooth on retromargin ( Fig. 149 ). Sternum yellow (in some specimens with brown marginal ring), mouthparts orange with pale tips. Abdomen oval, brownish, with yellow herring bone pattern, sides yellow with brown marks, venter light, mottled, in darker specimens with median grey streak. Bristles on abdomen sparse. Anterior spinnerets beige, posteriors brown. Legs yellowish, with dark brown rings at base of tibia and distal ends of tibia and metatarsus, first pair longest, brown. Tibia I with three pairs of ventral spines and single prolateral spine in basal part; metatarsus relatively long, with two pairs of ventral spines (all spines of medium length). Pedipalps as in Figs 148 , 150–154 , tibial apophysis short and pointed, cymbium dark brown, bulb with irregular shape, divided into two lobes by longitudinal fossa, embolus emerging beneath distal end of fossa, embolus ribbon-like, coiled on bulb tip.

Female. Cephalothorax: length 2.6–2.7, width 1.9, height 0.9–1.2. Abdomen: length 3.5–4.0, width 2.3–2.9, height 0.9–1.0. Eye field: length 1.0–1.1, anterior width 1.6–1.7, posterior width 1.4–1.6. General appearance as in Fig. 147 . Similar to male, slightly larger and lighter coloured, with wider abdomen, smaller tooth on retrolateral edge of chelicerae, first pair of legs shorter. Palp with single retrolateral spine on tarsus ( Fig. 155 ). Epigyne with pair of pockets at epigastric furrow and two rounded deep depressions in anterior part ( Fig. 156 ). Internal structure as in Fig. 157 , seminal ducts membranous, broad in their initial parts, looping posteriorly, entering small bicapsular spermathecae mesially.

Distribution. Species known from Kilimanjaro massif, Mt Meru and Ngorongoro.

Remarks. The type series contain 3♂ 13♀ (syntypes). One male (largest, in good condition) is designated as the lectotype and the others as paralectotypes for stability of the nomenclature.
