Diagnosis.
This species resembles
P. crypticolens
in the shape of the palpal bulb, but can be distinguished from it by the shape of the procursus tip (
Figs. 47F–G
), by the triangular tip of the appendix (
Fig. 47F
), and by the sclerotized anterior arch of the epigynum (
Fig. 47B
).
Redescription.
Male: A specimen measured (
holotype
), total length 3.4: cephalothorax 1.0 long, 1.0 wide; abdomen 2.4 long, 0.8 wide. Leg I: 21.8 (6.3+0.7+6.2+7.2+1.5), tibia II: 3.2, tibia III: 2.8, tibia IV: 3.5; Tibia I L/D: 48. Prosoma shape as in
Fig. 47C
. Carapace short, broad and almost circular, ochre, with pair of brown marks broadly connecting to ocular area. Cephalic region raised, with brown marks centrally, ocular area dark yellow. Clypeus 0.42, dark ochre, with yellow marks. Distance AME–AME 0.05. Diameter AME 0.06, ALE 0.17, PME 0.14, PLE 0.17. Chelicerae as in
Fig. 47D
, with pair of black apophyses distally, pair of unsclerotized thumb-shaped apophyses proximolaterally and pair of small unsclerotized rounded apophyses proximocentrally. Labium and endites slightly yellow. Sternum with seven regular yellowish brown spots. Femora, patellae, tibiae and metatarsi ochre, with numerous dark brown dots on them, tarsi brown. Abdomen cylindrical, pale ochre, dorsum with numerous small blackish brown spots as in
P. crypticolens
. Venter pale brown, with dark brown longitudinal stripe centrally. Palps as in
Figs. 47F and 47G
, with a long uncus, appendix with a large triangular tip.
Female: in general very similar to male. A specimen measured (‘allotype’), total length 3.5: cephalothorax 1.0 long, 1.0 wide; abdomen 2.3 long, 1.0 wide. Tibia I: 4.7. Distance AME–AME 0.05. Epigynum distinctly triangular as in
Fig. 47A
, with a knob-shaped apophysis on the top. Dorsal view as in
Fig. 47B
, with a sclerotized arch resembling grasping fingers anteriorly and a pair of large oval pore plates centrally.
