description: <i>Pseudonicsara (P.) nomo</i> sp. n. Figs. 27, 58, 97, 131, 170, 229, 262, 307, 350, 395, 455, 491, map 1. Holotype (male): Indonesia, Papua: W. New Guinea, Mt. Nomo S. of Mt. Bougainville, 213 m, 2° 42' S, 139° 59' E, II.1936, L.E. Cheesman, depository: The Natural History Museum, London, United Kingdom (BMNH). Paratype: 1 female, same data as holotype (BMNH). <b>Diagnosis.</b> The male cercus of <i>P. nomo</i> is similar to that of <i>P.stylata</i> in that the apico-internal process has the apex suddenly constricted with the distal angle being spinose, the proximal angle obtuse. It differs by the baso-internal process of the cercus being of medium length, little undulate and at apex with a spinule (Figs. 170, 229). <i>P. nomo</i> also differs from <i>P. stylata</i> by the epiproct that has the apical area bent distad and the apex truncate (Fig. 97), and by the oval apical parts of the titillators (Fig. 350). The female is characterised by the subgenital plate that has in middle of the basal area a large triangular groove, divided by a stout median carina; laterally is a large groove at each side extended into the apical lobes, which are obtuse and moved latero-dorsad (Fig. 455). Differences to other species are outlined in the key. <b>Description.</b> 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 8 external, 6 internal; mid femur 6–7 external, 2–3 internal near base; hind femur 10–12 external, 5–7 minute internal near base. Male. Stridulatory file slightly sinuate, 2.3 mm long; teeth at apex very dense and indistinct; with 86 teeth or 37.7 teeth per mm, in middle of file with 32.3 teeth per mm (Fig. 58). Mirror pentagonal with rounded angles; fore and hind margins straight; 1.7 mm long 1.5 mm wide; index length:width 1.1. Tenth abdominal tergite with apical margin roundly excised in middle, little projecting on both sides (Fig. 97). Epiproct short, apex truncate, dorsally furrowed (Fig. 97). Paraproct with compressed obtuse projection. Cerci cylindrical, slightly curved, with two internal projections: one at end of basal quarter, the other at apex (Figs. 131, 170, 229). Baso-internal projection digitiform, curved. Apico-internal projection narrow, curved, nearly parallelsided; with spine at tip. Cercus apex proper little swollen, obtuse. Subgenital plate at apex roundly excised (Fig. 262). Titillators separate; basal parts rather broad, little twisted; apical parts long-oval. Surface of apical parts densely covered with clinging hairs; apico-lateral margin convex, with short transverse and longer crests interrupted by furrows; coarsely granular (Figs. 307, 350, 395). Apico-lateral sclerites large, oval, hyaline. Female. Tenth abdominal tergite furrowed in midline. Subgenital plate divided in midline by a large triangular groove with low median carina; on both sides of groove greatly swollen; resulting lateral plates with large basal groove; basal grooves subdivided by a fold; apical area forming an obtuse lobe (Fig. 455, 491). Lateral sclerites near base of subgenital plate obtuse. <b>Coloration.</b> Yellowish brown. Face with black band between eyes including scapus; with another black band along clypeo-frontal suture extended on genae; both connected by a vertical black band widening ventrad (Fig. 27). Mandibles black except at base. Pronotal disc medium brown; anterior area with a yellow spot. Tegmen with pattern of dark cells and light veinlets distinct. Fore tibia infumate in anterior area especially near tympana. <b>Measurements:</b> body male 33, female 32; pronotum male 8.7, female 9.0; tegmen male 31, female 33.5; hind femur male 19, female 22; ovipositor female 20.5 mm. <b>Etymology.</b> Named after the type locality; noun in apposition.
