description: <i>Pseudonicsara (P.) finister</i> sp. n. Figs. 67, 104, 135, 180, 237, 267, 316, 365–366, 391, 406, 451–452, 495, map 1. 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). Paratypes: 2 females, same data as holotype (BPBM); 1 male, same locality, 1–28.VIII.1958 (BPBM). <b>Diagnosis.</b> 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 <i>P. crassicercus</i>, <i>P. karimui</i>, <i>P. concha</i>, and <i>P. clavus</i> with two subspecies. <i>P. finister</i> 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 <i>P. clavus</i>, <i>P. maritima</i>, <i>P. wum</i>, and <i>P. wau</i>. 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). <b>Description.</b> 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). <b>Coloration.</b> 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. <b>Measurements</b> (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. <b>Etymology.</b> Named after the type locality, name shortened; noun in apposition.
