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
with
Fig. 15A–C
).

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
). 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
). Copulatory openings hidden in very deep atria, accessory glands connected to spermathecae (

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
with
Fig. 6A–D
).

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
. Carapace abruptly sloping posteriorly (
Fig. 9B
), 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
. 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
). 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
) and thin horizontal apophysis on dorsum (
Fig. 9H
). Embolus nearly straight, only the tip curved to retrolateral side, with large accompanying membrane (
Fig. 9E–G, J–K
).
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
).
GENITALIA. Epigyne strongly sclerotized, especially in the anterior part, with pair of pockets in front of the epigastric fold (
Fig. 10A–F
; figures show intraspecific variation). Internal structure as in
Fig. 10G– H
, 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.
