Diagnosis. Males differ from those of P. carnarvon sp. nov. in having three pairs of strong spines ventrally on tibia I rather than four pairs of weak spines; also, the curvature of the carapace profile in P. jilbadji sp. nov. is similarly curved on either side of midpoint whereas in P. carnarvon sp. nov. it is more or less flat from the fovea forward. Female unknown.

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

Description Holotype male WAM96/1662

Carapace 2.71 long, 1.81 wide. Abdomen 2.96 long, 1.43 wide. Total length 5.8.

Colour: carapace smooth orange brown with blue bloom. Dorsal abdominal scute for 0.8 of length, darker brown with blue-green bloom anteriorly and centrally a broad median triangular pallid zone similar in cuticle to dark zone; abdomen with uniform cover of large brown feathery hairs; legs light orange brown with long stripes of dark hair along dorsal and lateral femora and dorsal patellae-metatarsi. Carapace: long white hairs for anterior half of carapace with long black bristle behind each PLE and on clypeus edge below each ALE; otherwise light cover of fine black setae; fovea at edge of long convex posterior slope. Margins smooth; cuticle finely rugose. Caput descends strongly to eyes from anterior to fovea. Legs: black feathery hairs on femora to tibiae. Femur IV distally unmodified. Spines: I: fe p1d3; ti v2.2.2, all strong; me v2.2. II: fe p1d3; ti v2.2; me v2.2. III: fe p2d3r1; pa d1; ti p2r2v2.2.1; me p3r3v2.2.1. IV: fe p1d3r1; pa d1; ti p2d1r2v2.2.2; me p3r3v2.2.2. Palp: fe p1d2r1; ti p2. Palp: cymbium with slight apical twist; paracymbial spine large, conical, slightly recurved on large coniform base. Subtegular lobe semicircular retrolaterally, evident prolaterally. Pre-embolar ridge low; basal spiral flat, much smaller than broad distal spiral, tip directed into cymbium tip. Abdomen: ventral scute narrow, laterally straight, distinctly constricted only posteriorly; dorsal scute posteriorly concave; petiolar collar short.
