Figs. 12, 68, 107, 182, 266, 319, 367, 407, map 2.

Holotype (male): Papua New Guinea, Morobe Prov.: New Guinea (NE), Bulolo [7° 10' S, 146° 40' E], 1200 m, 17.VIII.1956, E.J. Ford Jr., depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA ( BPBM).

Diagnosis. The new species comes close to P. zugi sp. n. It differs by the male cerci with the ventral basointernal process standing closer to the base than the dorsal baso-internal process ( Fig. 182) instead of both standing upon each other in the middle of the cercus. The apico-internal process is shorter. The apical parts of the titillators are long-oval but little angular with the apex rounded ( Fig. 367) instead of oval with the apex truncate. The titillators are similar to those of P. finister . P. spatula differs by the male cerci having a dorsal cone and different shapes of the apico-internal and baso-internal processes ( Fig. 182). 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 1.5 mm; greatest diameter of eye 1.7 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, 6 internal; mid femur 6 external, 1-3 internal near base; hind femur 11-17 external, 5 minute internal near base.

Male. Stridulatory file sinuate, 2.5 mm long; teeth at apex very dense and indistinct; with 94 teeth or 38.0 teeth per mm, in middle of file with 29.5 teeth per mm ( Fig. 68). Mirror narrowing posteriorly; hind margin straight; 1.6 mm long, 1.4 mm wide; index length:width = 1.1. Tenth abdominal tergite slightly globular; apical margin roundly excised in middle, little projecting on both sides ( Fig. 107). Epiproct elongate, narrow, deeply furrowed. Paraproct with transverse, compressed, dorsally concave projection. Cerci cylindrical, slightly curved; with three internal projections: two in middle, one at apex; of the former is the ventral little more basal than the dorsal ( Fig. 182). Dorso-internal projection small, obtuse, compressed; ventro-internal projection small, obtuse, compressed. Apico-internal projection long compressed with rather broad, subtruncate apex. Cercus apex proper with a short cone on top; subgenital plate apex deep roundly excised. Subgenital plate wider than long; apex roundly excised ( Fig. 266).

Titillators separate; basal parts about half as wide as apical parts; apical parts long-oval but little angular. Surface of apical parts densely covered with clinging hairs; apico-lateral margin coarsely granular. Basolateral sclerites curved, irregular. Apico-lateral sclerites oval, hyaline, hardly sclerotised ( Figs. 319, 367, 407).

Female unknown.

Coloration. Yellowish brown. Face with black band between eyes including scapus; with a black triangular spot at clypeo-frontal suture; both connected by a vertical black band. Tegmen with pattern of dark cells and light veinlets little distinct.

Measurements of male: body 30; pronotum 7.8; tegmen 28; hind femur 18; antenna 100 mm.

Etymology. The name refers to the spatulate apical tooth of the male cerci; noun in apposition.
