Long and slender, parallel-sided, with protruding head and long, thick antenna. BL 1.6 mm, BL/BW ~2.2, PW corresponds to ~80% of BW, HCW is ~80% of PW, length of antenna ~80% of total length.

Pronotum subcordiform, rounded sides distinctly beaded, no setae projecting over the edge. A member of the P. antarcticus- group with very thick male antennae. Terminalia generally similar to the other two species in the group. Male. Segment 8 and T9 (Figs 16, 17) as in P. antarcticus Watts and P. wattsi Zwick. S 9 with more strongly divergent caudal lobes including a wide regularly U-shaped space between them (Fig. 18), with a few indistinct sensilla on tips, basal sclerites parallel and wider apart than in relatives. Tegmen with oval notch between parameres, similar to P. antarcticus but stouter, lateral flanges extending further forward (Fig. 19). Penis (Fig. 20) with narrow mushroom-shaped trigonium, deep notches separate it from the parameroids. Apex with a cap-like sclerotization from which a thin spur extends forward. Parameroids intermediate between relatives in length but (unlike in relatives) very wide, overlapping at base and meeting at apex.
