Holotype (male): Papua New Guinea, East Sepik Prov.: D. N. Guinea, Kaiserin Augustafl. Exp. 61, am Maifluss [4° 18' S, 141° 50' E], V.1912, Ledermann, depository: Museum für Naturkunde der Humboldt- Universität , Berlin, Germany ( ZMB).

Diagnosis. The new species is similar to P. pugio sp. n. in that it has the tenth abdominal tergite with triangular apical lobes ( Fig. 99), the epiproct quadrangular ( Fig. 133), and the apico-internal process of the cercus in basal half plain ( Fig. 171). It differs by the epiproct being narrow, the apico-internal process of the cercus pointing medio-distad and suddenly narrowing before apical spine ( Fig. 171, 230), and the apical parts of the titillators being faintly angular ( Figs. 351–352). For differences to other species see key.

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 0.8. Face subrugose with numerous shallowly impressed dots. Tegmen little surpassing hind knees; rather narrow; basal two thirds with pre-subcostal area widened, apical third narrow. Femora with the following number of spines on ventral margins: fore femur 8 external, 6–7 internal; mid femur 7–8 external, 3–4 internal near base; hind femur 11 external, 7–10 minute internal in basal area.

Male. Stridulatory file 2.2 mm long; with 82 teeth or 38.0 teeth per mm plus 7 granules at apex; in middle of file with 32.3 teeth per mm ( Fig. 59). Mirror pentagonal with rounded angles; hind margin straight; area behind mirror with spinules ( Fig. 85); mirror 1.6 mm long 1.4 mm wide; index length:width 1.2. Tenth abdominal tergite transverse, slightly globular in middle; apical margin roundly excised in middle and triangularly projecting at both sides of excision; setose in middle and at apex ( Fig. 99). Epiproct quadrangular, margins raised and surface deeply furrowed; apical angles swollen, apex truncate ( Fig. 133). Projection of paraproct obtuse [distorted in specimen at hand]. Cerci conical, slightly curved; dorso-internal angle forming a lamella which terminates at proximal end in a downcurved projection with obtuse apex carrying a spinule and at distal end in a long compressed projection with acute apex just before obtuse apex of cercus ( Figs. 133, 171, 230). Subgenital plate with very small styli ( Fig. 263).

Titillators with apical parts rather small, ovoid, ventro-apical surface dark brown with clinging hairs, margin undulate, granular ( Figs. 308, 341, 351–352, 396).

Female unknown.

Coloration. Uniformly medium brown. Face reddish brown, median ocellus white; antennal scrobae, ventral area of scapus, a transverse band at clypeo-frontal suture and mandibles dark brown. Tegmen with network of light veins and veinlets and dark cells little conspicuous.

Measurements of male: body 31, pronotum 8.7, tegmen 29, hind femur 18.7 mm.

Etymology. The name refers to the apical tooth of the male cerci pointing nearly backwards.
