Holotype (male): Papua New Guinea, Madang Prov.: Apingan [4° 21' S, 144° 53' E], 15.VI.1982, P. Grootaert, depository: Collectio Fer Willemse, Eygelshoven, Netherlands ( CW), later to be deposited in Naturalis, Leiden ( RMNH).

Diagnosis. The new species is close to P. abbreviata with regard to the fastigium verticis having the dorsal margin rounded ( Fig. 35) and to the male characters. It differs by the dorsal lamella of the apicointernal tooth of the male cercus being rounded instead of angular ( Fig. 132), the baso-internal process of the cerci being rather short, obtuse ( Fig. 173), and by the apical parts of the titillators distinctly widened, triangular, with broad margin ( Figs. 339–340, 373). Differences to other species are outlined in the key.

Description. Fastigium verticis slightly curved ventrad ( Fig. 35), rather long for the genus but still shorter than scapus, ventral margin curved but not separated from fastigium frontis. Fastigium verticis in front of eyes 1.6 mm, from base 2.0 mm; dorsal eye length 1.8 mm; greatest diameter of eye 1.9 mm; index fastigium verticis from base: eye length 1.1. Face subrugose but impressed dots in midline of face very shallow, more distinct towards genae. Tegmen little surpassing hind knees, rather narrow, especially in apical third. Femora with the following number of spines on ventral margins: fore femur 7 external, 6 internal; mid femur 6 external, 2–3 internal near base; hind femur 10–11 external, 10 internal (8–9 in basal area, 1–2 near apex).

Male. Stridulatory file sinuate, 2.5 mm long; teeth medium large, at apex very narrow and small; with about 90 teeth or 36.3 teeth per mm, in middle of file with 30.4 teeth per mm ( Fig. 61). Mirror rectangular with rounded angles; widening anteriorly; apical margin straight with broadly rounded angles; 1.6 mm long 1.5 mm wide; index length:width = 1.0. Tenth abdominal tergite transverse but slightly globular in centre; apical margins broad and shallowly excised in middle ( Fig. 96). Epiproct narrow, elongate, with margins raised and deeply furrowed in middle ( Fig. 132). Cerci rather stout and little curved, with one obtuse basointernal process with flattened ventral surface and one compressed, roughly long-triangular, acute apicointernal process that has a rounded dorsal lamella at base ( Figs. 132, 173, 206, 233). Paraproct with projection transverse, swollen, obtuse. Subgenital plate with a pair of rounded carinae the dorsal margin of which extending slightly behind the bases of the small styli ( Fig. 279).

Titillators with basal part broad, base rounded; apical parts roughly triangular but angles broadly rounded; internal surface covered with clinging hairs; margin irregularly undulate, granular ( Figs. 325, 339–340, 373, 410).

Female unknown.

Coloration. In lateral view yellowish brown (green when alive?), in dorsal view dark reddish brown without a distinct borderline between both patterns. Face reddish brown in centre, yellowish brown (green when alive?) towards genae; antennal scrobae and fastigium frontis black, median ocellus light; a black transverse band along clypeo-frontal suture is narrowly extended laterad along bases of mandibles; apex of mandibles black. Vertex with a dark brown spot from behind compound eyes to hind margin. Pronotum with disc and dorsal area of paranota dark brown with a pale brown spot between fore margin and transverse sulcus; ventral area of paranota yellowish brown (pattern not striking). Tegmen with light veins and infumate cells in basal half, uniformly yellowish transparent in apical half. Fore tibia with dorsal surface indistinctly infumate. Genicular area of mid and hind femora and apical area of mid and hind tibiae more or less infumate; dorsal spines of hind tibia sitting on not very distinct dark spots. Light/dark pattern not striking.

Measurements of male: body 33, pronotum 8.7, tegmen 31.5, hind femur 20.5 mm.
