Holotype (male): Papua New Guinea, West Sepik: D. N. Guinea, Berlinhafen [Arop (W. of Aitape), 3° 8' S, 142° 15' E], H. Schoede, depository: Museum für Naturkunde der Humboldt-Universität, Berlin, Germany ( ZMB).

Diagnosis. The male cercus of P.stylata is similar to that of P. nomo in that the apico-internal process has the apex suddenly constricted with the distal angle spinose, the proximal angle obtuse. It differs by the basointernal process of the cercus being long, hook-shaped ( Fig. 169). P. stylata also differs from P. nomo by the triangular epiproct ( Fig. 94), and by the apical parts of the titillators being bellied with straight oblique apex ( Fig. 358). Differences to other species are outlined in the key.

Description. Fastigium verticis in front of eyes 1.4 mm, from base 1.8 mm; dorsal eye length 1.8 mm; greatest diameter of eye 2.0 mm; index fastigium verticis from base: eye length 1.0. Face subsmooth in middle but with some shallowly impressed dots, rugose towards genae. Tegmen little surpassing hind knees, costal field in basal two thirds broad, in apical third narrow. Femora with the following number of spines on ventral margins: fore femur 8–9 external, 6 internal; mid femur 6 external, 3 internal near base; hind femur 11–12 external, 4–7 minute internal near base.

Male. Stridulatory file sinuate, 2.3 mm long; teeth at apex very dense and indistinct; with 85 teeth plus 8 spinules at apex or 36.2 teeth per mm, in middle of file with 30.4 teeth per mm ( Fig. 57). Mirror narrowing posteriorly; hind margin straight; 1.7 mm long, 1.6 mm wide; index length:width 1.1. Tenth abdominal tergite transverse but central area slightly globular; apical margin broad-roundly excised in middle and with a broadtriangular projection on both sides of excision ( Fig. 94). Epiproct triangular with apex rounded; lateral margins greatly raised and surface deeply grooved ( Fig. 94). Projection of paraproct obtuse. Cerci conical, slightly curved; internal surface with a weak lamella which carries a curved stylate projection with slightly widened tip at base, a ventral tubercle before middle and a long compressed projection at apex, which has the apico-proximal angle rounded and the apico-distal angle spined; apex of cercus swollen on dorsal surface, obtuse ( Figs. 130, 169, 203). Subgenital plate with styli shorter than excised area ( Fig. 261).

Titillators with apical parts roughly triangular but angle broadly rounded; interno-apical surface with clinging hairs, dark brown in centre, paler towards margin; margin medium brown, granular, somewhat irregular ( Figs. 312, 358, 399).

Female unknown.

Coloration. Ochreous brown (discoloured?). Face with a large transverse dark brown spot at clypeofrontal suture, a vertical dark brown band narrowing ventrad from fastigium frontis to the large ventral spot; median ocellus pale; antennal scrobae, ventral side of scapus and base of pedicellus dark brown. Tegmen yellow with dark spots.

Measurements of male: body 38, pronotum 9.3, tegmen 32, hind femur 22.

Etymology. Named for the long and narrow apical projection of the male cercus.
