Holotype (male): Papua New Guinea, Madang Prov.: New Guinea, NE, Finisterre Mts. , Saidor [5° 35' S, 146° 30' E], Kiambavi Village, 22–29.VII.1958, W.W. Brandt, depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA ( BPBM). GoogleMaps

Paratypes: 2 females, same data as holotype ( BPBM) GoogleMaps ; 1 male, same locality, 1–28.VIII.1958 ( BPBM) GoogleMaps .

Diagnosis. The new species belongs to a group of species that have the male cerci with two rather small baso-internal processes standing upon each other, a single apico-internal process, and the tip of the cercus without a dorsal cone ( Fig. 180). Other species with those characters are P. crassicercus , P. karimui , P. concha , and P. clavus with two subspecies. P. finister differs by the dorsal of the baso-internal processes being vertically inserted, the subgenital plate being wider than long ( Fig. 267), and especially by the shape of the titillators that are roughly hexagonal with rounded angles ( Figs. 365–366). The female subgenital plate is similar to those of P. clavus , P. maritima , P. wum , and P. wau . It differs by the basal, lateral and ventral surfaces being flattened or slightly concave and separated by rather distinct angles from each other similar to the shape of a cube ( Figs. 451–452, 495).

Description. Fastigium verticis in front of eyes 0.9 mm, from base 1.4 mm; dorsal eye length 1.6 mm; greatest diameter of eye 1.7 mm; index fastigium verticis from base: eye length 0.9 mm. 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 5–8 external, 5–6 internal; mid femur 5–7 external, 2–3 internal near base; hind femur 8–11 external, 1–5 minute internal near base.

Male. Stridulatory file sinuate, 2.3 mm long; teeth at apex very dense and indistinct; with 90–99 teeth or 40.0–42.8 teeth per mm, in middle of file with 31.3–33.2 teeth per mm ( Fig. 67). Mirror pentagonal with rounded angles; caudal margin oblique; 1.6 mm long 1.4 mm wide; index length:width 1.2. Tenth abdominal tergite with apical margin roundly excised in middle, little projecting on both sides ( Fig. 104). Epiproct elongate, narrow, deeply furrowed ( Fig. 135). Paraproct with little compressed projection. Cerci cylindrical, slightly curved, with three internal projections: two in middle, one at apex ( Figs. 135, 180, 237). Dorsointernal and ventro-internal projections small, digitiform. Apico-internal projection long, compressed, with obtuse apex. Subgenital plate at apex deep roundly excised ( Fig. 267).

Titillators separate; basal parts rather broad, little twisted; apical parts roughly hexagonal with rounded angles ( Figs. 316, 365–366, 391, 406). Surface of apical parts densely covered with clinging hairs; apicolateral margin convex, coarsely granular. Baso-lateral sclerite curved with quadrangular hyaline appendage. Apico-lateral sclerites oval, hyaline, hardly sclerotised.

Female. Tenth abdominal tergite furrowed in midline. Subgenital plate divided in middle by triangular membranous area; lateral plates short, curved; lateral areas strongly upcurved; internal margin concave, external convex ( Figs. 451–452, 495).

Coloration. Yellowish brown. Face with black band between eyes including scapus; with another black band along clypeo-frontal suture. Tegmen with pattern of dark cells and light veinlets little distinct.

Measurements (2 males, 2 females): body male 30–31, female 29–30; pronotum male 7.8–8.0, female 7.5; tegmen male 27.5, female 28.0–28.5; hind femur male 18.5, female 19.5; antenna male 100–110; ovipositor female 19.0– 19.5 mm.

Etymology. Named after the type locality, name shortened; noun in apposition.
