Holotype (male): Papua New Guinea, Morobe Prov.: New Guinea (NE), Huon Peninsula, Pindiu [6° 27' S, 147° 31' E], 750–850 m, 21.IV.1963, J. Sedlacek, depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA ( BPBM).

Paratypes: Papua New Guinea: 1 female, same data as holotype ( BPBM); 1 female, Morobe Prov.: New Guinea (NE), Huon Peninsula, Zengaren [6° 25' S, 147° 25' E], 1200 m, 28.IV.1963, J. Sedlacek ( BPBM) .

Diagnosis. The new species shares with P. concha sp. n. that the male apico-internal process of the male cercus is pointing nearly ventrad and provided with a dorsal crest or lamella at base. It differs by the free apical area of that process being about as long as or longer than the basal area with crest ( Fig. 136). Further differences are the narrow apical excision of the male subgenital plate ( Fig. 283) and the shape of the apical parts of the titillators that are oval with the apex oblique and the margin entire ( Fig. 354). The female subgenital plate is acute-triangularly divided in midline by a membranous zone. The resulting lobes have the baso-proximal angles little projecting, the internal margin concave and the external margin convex; on proximal surface there is a wide furrow, while on external surface they are shallowly grooved ( Figs. 453, 501). Differences to other species are outlined in the key.

Description. Fastigium verticis in front of eyes 1.2 mm, from base 1.6 mm; dorsal eye length 1.6 mm; greatest diameter of eye 1.8 mm; index fastigium verticis from base: eye length 1.0. Face rugose but shining. Tegmen surpassing apices of hind femora; gradually narrowed behind basal widening. Femora with the following number of spines on ventral margins: fore femur 7–8 external, 5–6 internal; mid femur 6 external, 3 internal near base; hind femur 9–13 external, 4–7 minute internal near base.

Male. Stridulatory file sinuate, 2.3 mm long; teeth at apex very dense and indistinct; with 97 teeth or 42.5 teeth per mm, in middle of file with 30.4 teeth per mm ( Fig. 63). Mirror with approaching margins in apical third; fore margin straight, hind margin oblique; 1.7 mm long, 1.4 mm wide; index length:width 1.2. Tenth abdominal tergite slightly globular; apical margin roundly excised in middle, little projecting on both sides ( Fig. 101). Epiproct elongate, narrow, deeply furrowed. Paraproct with compressed triangular projection. Cerci cylindrical, slightly curved, with three internal projections: two in middle, one at apex; of the former the ventral little closer to base than the dorsal ( Figs. 136, 176, 205, 235). Dorso-internal projection compressed, triangular; ventro-internal projection small, digitiform. Apico-internal projection long, compressed, with obtuse apex. Subgenital plate at apex roundly excised ( Fig. 283).

Titillators separate; basal parts rather broad, little twisted, simple; apical parts roughly triangular with rounded angles. Surface of apical parts densely covered with clinging hairs; apico-lateral margin substraight, angles rounded, coarsely granular ( Figs. 310, 354, 398). Baso-lateral sclerite curved with quadrangular hyaline appendage. Apico-lateral sclerites large, oval, hyaline.

Female. Tenth abdominal tergite furrowed in midline. Epiproct triangular with apex obtuse; dorsally furrowed. Subgenital plate divided in midline by membranous area; lateral plates with a strong obtuse carina running laterad and covering apico-lateral margin of sclerite in ventral view; with groove at base; internal margin concave, apex truncate ( Figs. 453, 501, 533).

Coloration. Yellowish brown. Face with black band between eyes including scapus, less distinct on genae; with a black band along clypeo-frontal suture extended on genae. Pronotum yellowish brown; disc darkened especially in fore and hind areas, interrupted by yellowish brown round marks. Tegmen with dark cells and light veinlets.

Measurements (1 male, 2 females): body male 30, female 30; pronotum male 7.5, female 7.5; tegmen male 27, female 27.5–28.0; hind femur male 18, female 18–20; ovipositor female 16.5–17.0 mm.

Etymology. Named for the shape of the apical tooth of the male cerci; noun in apposition.
