Fig. 7 View Fig. 7
Etymology
The specific name refers to the presence of an apophysis on the palpal patella.
Type material
Holotype
GUINEA: Ƌ, Mts Nimba , grassy area, 1952–1962, M. Lamotte leg. ( NHM).
Paratype
GUINEA: 1 Ƌ, together with holotype ( NHM).
Differential diagnosis
The male is similar to that of P. poissoni comb. nov. in having an embolus with accompanying membrane, but may be distinguished by the presence of a small patellar apophysis ( Fig. 7A, C, F–G View Fig. 7 ).
Description
Male
DIMENSIONS. Cephalothorax: length 2.3–2.4, width 1.9–2.1, height 1.3–1.5. Eye field: length 1.2–1.4, anterior width 1.8–1.9, posterior width 1.6–1.8. Abdomen: length 1.9–2.2, width 1.4–1.5.
COLOUR AND BODY. Carapace brownish with slopes slightly darker but covered by light hairs. Anterior eyes encircled by fawn scales. Abdomen greyish with large light patch in anterior half and chevrons posteriorly, clothed in fine hairs, among them some longer bristles. Legs yellow with darker rings.
GENITALIA. Pedipalps pale, yellowish. Palpal organ as in Fig. 7A–G View Fig. 7 . Short but clear retrolateral apophysis on palpal patella ( Fig. 7A, C, F–G View Fig. 7 ). Embolus slightly curved to prolateral side, with accompanying membrane ( Fig. 7A View Fig. 7 ).
Female

Differential diagnosis
The female has an epigyne similar to that of P. spiniger sp. nov., sharing the V-shaped anterior epigynal depression and the absence of pockets, but may be distinguished by having a broader area occupied by the atria than that of P. spiniger sp. nov. in comparison to the area surrounding the spermathecae (compare Fig. 8B–C View Fig. 8 with Fig. 15A–C View Fig. 15 ).

Male
Unknown.
Female
DIMENSIONS. Cephalothorax: length 2.1, width 1.7, height 1.2. Abdomen: length 2.0, width 1.6. Eye field: length 1.1, anterior width 1.5, posterior width 1.4.
COLOUR AND BODY. Carapace dark brown, covered with fine hairs. Eye field darker, some brown bristles at anterior eyes. Abdomen brown with lighter herring-bone pattern dorsally and numerous patches on lateral sides ( Fig. 8A View Fig. 8 ). Spinnerets brownish. Legs long, yellow, with delicate yellowish hairs.
GENITALIA. Epigyne strongly sclerotized, especially anteriorly where characteristic plate with small depression between atria is situated ( Fig. 8B–C View Fig. 8 ). Copulatory openings hidden in very deep atria, accessory glands connected to spermathecae ( Fig. 8D View Fig. 8 ).

Hernard et al. leg. ( MRAC 238 838B ). GoogleMaps
Differential diagnosis
The male is similar to that of P. patellaris sp. nov. in having an embolus with accompanying membrane, but may be distinguished by the orientation of the embolar tip (retrolateral in P. poissoni comb. nov., prolateral in P. patellaris sp. nov.) and by the absence of a patellar apophysis. The female is slightly similar to that of P. obstipa sp. nov.; both species have an epigyne with paired pockets placed near the epigastric furrow at the level of the spermathecae, but P. poissoni comb. nov. can be separated by the clearly smaller atria and characteristic wavy edge of the atrial area (compare Fig. 10A–F View Fig. 10 with Fig. 6A–D View Fig. 6 ).
Redescription
Male
DIMENSIONS. Cephalothorax: length 2.3, width 1.4, height 1.1. Abdomen: length1.5, width 1.0. Eye field: length 0.9, anterior width 1.4, posterior width 1.3.
COLOUR AND BODY. General appearance as in Fig. 9A View Fig. 9 . Carapace abruptly sloping posteriorly ( Fig. 9B View Fig. 9 ), covered with delicate colourless hairs, some white hairs on slopes. Anterior medians lack black rings, long bristles near eyes. Fovea visible. Clypeus low, with white hairs. Chelicerae dark yellow, fang short, dentition as in Fig. 9C View Fig. 9 . Labium, endites and sternum dark yellowish. Abdomen smaller than cephalothorax, oval, yellowish grey (probably bleached) with traces of lighter chevrons in posterior half, some brown bristles on abdominal dorsum, denser at anterior edge. Spinnerets yellow. Legs long, light brown. Ventral spines of tibia and metatarsus extremely long ( Fig. 9D View Fig. 9 ). Short, stiff and sharp hairs on ventral surface of first femur.
GENITALIA. Pedipalps yellow with white hairs on cymbium, tibia short with short broad retrolateral and prolateral apophyses ( Fig. 9F, J View Fig. 9 ) and thin horizontal apophysis on dorsum ( Fig. 9H View Fig. 9 ). Embolus nearly straight, only the tip curved to retrolateral side, with large accompanying membrane ( Fig. 9E–G, J–K View Fig. 9 ).
Female
DIMENSIONS. Cephalothorax: length 2.0–2.2, width 1.5–1.8, height 1.0–1.1. Abdomen: length 2.0–2.6, width 1.4–1.9. Eye field: length 1.0–1.2, anterior width 1.5–1.8, posterior width 1.4–1.7.
COLOUR AND BODY. Shape of body as in male, only leg I shorter. Some white hairs on slopes of carapace. Chelicerae as in male, only retromarginal tooth slightly smaller. Abdominal pattern with more contrast than in male, two parallel light bands on greyish background in anterior part and a few chevrons posteriorly. Legs yellow, darker rings on bases and ends of segments. Retrolateral spine on palpal tarsus ( Fig. 10A View Fig. 10 ).
GENITALIA. Epigyne strongly sclerotized, especially in the anterior part, with pair of pockets in front of the epigastric fold ( Fig. 10A–F View Fig. 10 ; figures show intraspecific variation). Internal structure as in Fig. 10G– H View Fig. 10 , copulatory openings placed in deep atria, small accessory glands connected to spermathecae.
Remark
One male was found together with the holotype in the same vial, but this specimen is not mentioned in the original description.
