Diagnosis. The male of this species is distinctive in having a unique form of the embolus, with a flag-shaped enlargement near its tip ( Figs 100 View FIGURES 97–100 , 103 View FIGURES 101–109 ). The female has an epigyne similar to that in P. fastibilis , but can be recognized by the very short seminal ducts vs very long in the latter species (compare Fig. 113 View FIGURES 110–113 with Fig. 39 View FIGURES 36–39 ).

Redescription. Male. Measurements. Cephalothorax: length 2.4–3.1, width 1.9–2.4, height 1.3–1.6. Eye field: length 1.1–1.5, anterior width 1.7–2.1, posterior width 1.6–1.9. Abdomen: length 2.2–2.9, width 1.1–1.5. General appearance as in Fig. 97 View FIGURES 97–100 . Carapace high, eye field brown, thoracic part dark yellow, sides dark brown. Eyes large, surrounded with black rings, anterior medians eyes framed with very small white scale-like hairs. Some delicate hairs on carapace, longer brown bristles near eyes. Clypeus with whitish hairs. Chelicerae large, with two small prolateral teeth and large retromarginal tooth ( Fig. 101 View FIGURES 101–109 ). Endites and labium light brown to dark, sternum orange. Abdomen elongate, brown, with whitish-yellow median band, diffused posteriorly to adjacent patches ( Fig. 97 View FIGURES 97–100 ). Spinnerets long, orange, with blackish ends. Legs light, whitish-yellow, with long femora. First leg longest, with numerous very long spines on ventral surfaces of tibia (four pairs) and on metatarsus (three pairs), shorter spines on lateral surfaces of these segments ( Figs 99 View FIGURES 97–100 , 102 View FIGURES 101–109 ). Single spine on prolateral surface of patella I. Pedipalp brown, with long hairs along prolateral surface its patella, tibia and cymbium. Tibia short ( Fig. 103 View FIGURES 101–109 ) or very long ( Figs 104, 108 View FIGURES 101–109 ), tibial apophysis short. Bulb oval, embolus broad basally, abruptly narrowing to thin tip ( Figs 103, 104, 107, 108 View FIGURES 101–109 ).

Female. Measurements. Cephalothorax: length 2.0–2.4, width 1.6–1.7, height 1.0–1.1. Eye field: length 1.0– 1.1, anterior width 1.5–1.6, posterior width 1.3–1.5. Abdomen: length 2.0–2.4, width 1.4–1.6. General appearance as in Fig. 98 View FIGURES 97–100 . Slightly smaller than male. Carapace oval, broad, high, dark brown, with wide white streaks along lateral edges and large arrow-shaped patch on foveal area. Eyes large, surrounded by black rings. Carapace covered with fine hairs, few longer bristles at anterior eyes. Clypeus extremely low, some white hairs on it. Chelicerae dark brown, unidentati, with short fang. Endites and labium yellowish, sternum large, rounded, yellow. Abdomen oval, blackish, with pattern composed of yellow patches ( Fig. 98 View FIGURES 97–100 ), clothed in delicate hairs, sparse brown bristles at anterior edge. Venter lighter than dorsum. Spinnerets yellowish-grey. Legs yellowish-orange, with grey marks, distal segments of legs I darker, leg hairs brown. Femora III and IV long. Tibia I with four pairs of long ventral spines, metatarsus with three pairs. Palp with long retrolateral tarsal spine. Epigyne with shallow depression divided by narrow elevated ridge ( Figs 110, 111 View FIGURES 110–113 ). Two parallel troughs leading to copulatory openings ( Fig. 112 View FIGURES 110–113 ), seminal ducts very short, spermathecae large, bean-shaped ( Figs 112, 113 View FIGURES 110–113 ).

Distribution. Known from western Africa: Nigeria, Gabon, Cameroon ( Fig. 159 View FIGURE 159 ).

Remarks. The holotype of P. occidentalis differs from P. pulchra only in having of twice shorter palpal tibia. The length of this segment is very variable; among the specimens collected in Calabar area two individuals have short tibia, and one long. The majority of specimens have the palpal tibia medium-sized. Similar variation was observed also in other species, e.g. in Tusitala barbata Peckham & Peckham, 1902 and T. hirsuta Peckham & Peckham, 1902 (Wesołowska & Cumming 2008; Azarkina & Foord 2015). In our opinion these specific names are synonyms.

The female of this species is described here for the first time.
