Figs. 83, 114, 190, 243, 294, 324, 342, 377, 409, map 4.

Holotype (male): Indonesia, Papua: New Guinea, Neth., Vogelkop: Bomberi [Jazirah Bomberai 3° 0' S, 133° 0' E], 700–900 m, 5.VI.1959, J.L. Gressitt, depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA ( BPBM).

Diagnosis. The new species is unique within the genus in that the male cercus has a single internal process only, little behind middle of length; the process is diagonally twisted: basal and dorsal areas are laterally compressed, terminating in a short cone, while ventral and apical areas are dorso-ventrally compressed, widening and terminating into two short obtuse lobes ( Fig. 190). The male subgenital plate has as unique character that the central part is projecting between the styli ( Fig. 294). The apical parts of the titillators are long and narrow, at base with a fold, while the margin is elongate cap-shaped ( Fig. 377). Another unique feature is the stridulatory file with the teeth standing about twice as dense as in most other species of the genus ( Fig. 83).

Description. Small for the genus. Fastigium verticis in front of eyes 0.7 mm, from base 1.1 mm; dorsal eye length 1.1 mm; greatest diameter of eye 1.3 mm; index fastigium verticis from base: eye length 0.9. Face rugose but shining. Brachypterous; wings not reaching apices of hind femora; tegmen gradually narrowed behind basal widening; apex narrowly rounded. Femora with the following number of spines on ventral margins: fore femur 7–8 external, 6–7 internal; mid femur 6 external, 2 internal near base; hind femur 8–10 external, 0 internal.

Male. Stridulatory area of left tegmen greatly projecting; stridulatory vein concave, at apex convex; 1.8 mm long; teeth near apex very dense and indistinct; with 120 teeth or 67.3 teeth per mm; in middle 58.1 teeth per mm ( Fig. 83). Mirror narrowing posteriorly; longer than wide; caudal margin of mirror convex; 1.2 mm long 1.0 mm wide; index length:width 1.2. Tenth abdominal tergite slightly globular in basal half, prolonged behind; apical margin with ovoid excision; projections on both sides of excision obliquely truncate with internal margins approaching each other ( Fig. 114). Epiproct rounded, faintly grooved; with two small tubercles near apex. Cerci short-cylindrical; little projecting behind tenth tergite; with internal projection at beginning of apical third; projection compressed, widening towards three-lobate apex ( Figs. 190, 243); basal of process with a projecting tubercle visible in ventral view only ( Fig. 243). Subgenital plate broad; apex almost truncate but with a shallow triangular excision in middle; styli thin ( Fig. 294).

Titillators sclerotised; separate. Basal parts very short and narrow; apical parts with a wide socket, then angular, narrowed and parallel-sided; apex truncate; surface of apical parts densely covered with clinging hairs; apico-lateral margin triangular with prolonged base, enlarged, coarsely granular; at caudal angle with a small spinose carina ( Figs. 324, 342, 377, 409). Baso-lateral sclerites elongate, faintly undulate. Apico-lateral sclerites oval, darkened.

Female unknown.

Coloration. Brown. Face with black vertical band widening ventrad; scapus black; mandibles with apical area black. Pronotal disc indistinctly infumate. Tegmen with dark cells and light veinlets. Fore tibia with three black marks: at and below tympana and before apex.

Measurements of male: body 22; pronotum 5.8; tegmen 13; hind femur 14 mm.

Etymology. Named after the type locality; noun in apposition.
