Holotype ♀ ( ZMMU), TAJIKISTAN, Khatlon Region, Dangara Distr., SW slope of Sanglogh (= Sanglok ) Mt. Range , 38°13.091'N, 69°14.282'E, clay-sand cliffs along road and among litter under Artemisia , 1362 m, 30.04.2015 (Y.M. Marusik) GoogleMaps .


The species epithet is a noun in apposition taken from the type locality.


The new species differs from those of P. astana sp. n. by the indistinct fovea and unconcealed copulatory openings (Co) (vs. fovea distinct, copulatory openings concealed by hoods), as well as by the copulatory ducts (Cd) directed posteriorly and the short glands of the receptacles (Rg) not extended anteriorly as much as the receptacles (vs. copulatory ducts directed anteriorly, and glands of receptacles located anterior to receptacles). The two species differ by the spination of tibia II: P. sanglok sp. n. has 5 pairs of ventral spines, whereas P. astana sp. n. has 4 pairs.


Female. Total length 2.18. Prosoma 0.5 high. Carapace: 1.03 long, 0.81 wide, 0.33 high. Prosoma and chelicerae brown. Legs and palps pale yellow, femora and coxae I darker than other segments. Abdomen and spinnerets white. Postgastral scuta elongate, ovoid, about 4 times longer than wide.

Epigyne as in Figs 29-32 View Figures 27–34 ; fovea indistinct, copulatory openings (Co) unconcealed, hood absent; copulatory ducts directed posteriorly; glands of receptacles short, shorter than anterior extension of receptacles, diverging.
