TYPE: Female holotype taken 41 km S of Mount Magnet, 28 ° 04 ̍ S, 117 ° 49 ̍ E, Western Australia (Aug. 8, 1982; B. Main), deposited in WAM (99/349) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of P. planus but have a shorter and distally incised retrolateral tibial apophysis (fig. 454); females resemble those of P. planus and P. pins but have a smaller epigynal atrium (fig. 455) and more rounded spermathecae (fig. 456).

MALE: Carapace length 3 (most of abdomen missing). Carapace light brown, portions of abdomen with specimen light gray, legs light brown. Leg spination (leg IV missing): femora I–III d1­1­0; tibiae: I v1p­1p­0; II v4­2­0; III v1p­1p­0; metatarsi: I v1p­0­0; II, III v2­0­0. Retrolateral tibial apophysis relatively short, wide, distally incised (fig. 454); embolus shorter than in P. planus , distal portion carried in groove of translucent portion of ventral prong of median apophysis (fig. 453).

FEMALE: Total length 8. Coloration as in male but abdominal dorsum with two distinct paramedian, longitudinal light stripes, venter white. Leg spination: femora I–IV d1­1­0; tibiae: I, II v4­2­0; metatarsi: I, II v2­0­0; III, IV v1p­0­0. Epigynal atrium relatively small, rounded (fig. 455), two spermathecal coils on each side, connected posteriorly by transverse duct (fig. 456).
