Type material. Holotype: male (IZCAS-Ar39786), near river (35°32’51.72”N, 72°34’9.12”E, elevation 2520 ± 12 m), Ankra Village , Kalam, Swat, Khyber Pakhtunkhwa, Pakistan, 3 June 2019, A. Ali leg. GoogleMaps Paratype: 1 female (IZCAS-Ar39787), same data as holotype GoogleMaps .

Etymology. The specific name refers to the type locality and is a noun in apposition.

Diagnosis. This species resembles P. arsacius Senglet, 2008 (see Senglet 2008: 363, figs 40–46, 55–56) with similar bulbal apophyses ( Fig. 4C View FIGURE 4 ), male chelicerae ( Fig. 4D View FIGURE 4 ) and epigynum ( Fig. 4A View FIGURE 4 ) but can be distinguished by subdistal membranous process of procursus not extending to distal part (arrow 1 in Fig. 3C View FIGURE 3 ), by presence of swollen prolateral apophysis distally on procursus (arrow 2 in Fig. 3C View FIGURE 3 ) and by inverted ‘w’-shaped vulval anterior arch ( Fig. 4B View FIGURE 4 ).

Description. Male (holotype, IZCAS-Ar39786): Total length 5.65 (5.85 with clypeus), carapace 1.71 long, 1.90 wide, opisthosoma 3.94 long, 1.66 wide. Leg I: 45.92 (11.86 + 0.83 + 12.00 + 18.49 + 2.74), leg II: 30.64 (8.73 + 0.78 + 7.86 + 11.64 + 1.63), leg III: 22.91 (6.67 + 0.76 + 6.01 + 8.33 + 1.14), leg IV: 28.46 (8.52 + 0.76 + 7.23 + 10.61 + 1.34); tibia I L/d: 48. Distance PME-PME 0.35, diameter PME 0.16, distance PME-ALE 0.05, distance AME-AME 0.06, diameter AME 0.07. Sternum wider than long (1.24/0.82). Habitus as in Figs 4 View FIGURE 4 E–F. Carapace yellowish, with brown marks medially; ocular area brownish, with brown marks posteriorly; clypeus and sternum yellowish, with brown marks. Legs yellowish, but brown on patellae and whitish on distal parts of femora and tibiae, without darker rings. Opisthosoma yellowish, without spots. Ocular area elevated, each eye triad on top of short laterally directed eye-stalk. Thoracic furrow absent. Chelicerae as in Fig. 4D View FIGURE 4 , with pair of proximo-lateral apophyses, pair of distal apophyses provided with two teeth each, and pair of frontal apophyses. Pedipalps as in Figs 3 View FIGURE 3 A–B; trochanter with long curved ventral apophysis; femur with small dorsal apophysis proximally (arrow in Fig. 3B View FIGURE 3 ) and distinct ventral protuberance; procursus simple, with two prolatero-dorsal spines (arrows in Fig. 3D View FIGURE 3 ) and swollen prolateral apophysis distally (arrow 2 in Fig. 3C View FIGURE 3 ); uncus with scaly edge ( Fig. 4C View FIGURE 4 ); appendix hooked, with indistinct angular apophysis medially (arrow in Fig. 4C View FIGURE 4 ); embolus weakly sclerotized, with some transparent projections distally ( Fig. 4C View FIGURE 4 ). Retrolateral trichobothrium of tibia I at 5% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi, without spines and curved setae; tarsus I with 30 distinct pseudosegments.

Female (paratype, IZCAS-Ar39787): Similar to male, habitus as in Figs 4 View FIGURE 4 G–H. Total length 6.26 (6.40 with clypeus), carapace 1.67 long, 1.81 wide, opisthosoma 4.59 long, 2.89 wide; tibia I: 9.91; tibia I L/d: 45. Distance PME-PME 0.27, diameter PME 0.16, distance PME-ALE 0.04, distance AME-AME 0.05, diameter AME 0.07. Sternum wider than long (1.08/0.80). Ocular area without brown patch posteriorly. Epigynum ( Fig. 4A View FIGURE 4 ) with knob. Vulva ( Fig. 4B View FIGURE 4 ) with inverted ‘w’-shaped sclerotized anterior arch, pair of sclerites, and pair of elliptic pore plates (posterior covered by sclerite, arrow in Fig. 4B View FIGURE 4 ).

Variation: Right procursus of holotype with only one prolatero-dorsal spine.

Distribution. Pakistan (Khyber Pakhtunkhwa, type locality; Fig. 5 View FIGURE 5 ).

Natural history. The species was found on the rock walls near the river.
