description: <i>Pseudonicsara (P.) clavus</i> sp. n. Figs. 63, 101, 136, 176, 205, 235, 283, 310, 354, 398, 453, 501, 533, map 2. Holotype (male): Papua New Guinea, Morobe Prov.: New Guinea (NE), Huon Peninsula, Pindiu [6° 27' S, 147° 31' E], 750–850 m, 21.IV.1963, J. Sedlacek, depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA (BPBM). Paratypes: Papua New Guinea: 1 female, same data as holotype (BPBM); 1 female, Morobe Prov.: New Guinea (NE), Huon Peninsula, Zengaren [6° 25' S, 147° 25' E], 1200 m, 28.IV.1963, J. Sedlacek (BPBM). <b>Diagnosis.</b> The new species shares with <i>P. concha</i> <b>sp. n.</b> that the male apico-internal process of the male cercus is pointing nearly ventrad and provided with a dorsal crest or lamella at base. It differs by the free apical area of that process being about as long as or longer than the basal area with crest (Fig. 136). Further differences are the narrow apical excision of the male subgenital plate (Fig. 283) and the shape of the apical parts of the titillators that are oval with the apex oblique and the margin entire (Fig. 354). The female subgenital plate is acute-triangularly divided in midline by a membranous zone. The resulting lobes have the baso-proximal angles little projecting, the internal margin concave and the external margin convex; on proximal surface there is a wide furrow, while on external surface they are shallowly grooved (Figs. 453, 501). 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 7–8 external, 5–6 internal; mid femur 6 external, 3 internal near base; hind femur 9–13 external, 4–7 minute internal near base. Male. Stridulatory file sinuate, 2.3 mm long; teeth at apex very dense and indistinct; with 97 teeth or 42.5 teeth per mm, in middle of file with 30.4 teeth per mm (Fig. 63). Mirror with approaching margins in apical third; fore margin straight, hind margin oblique; 1.7 mm long, 1.4 mm wide; index length:width 1.2. Tenth abdominal tergite slightly globular; apical margin roundly excised in middle, little projecting on both sides (Fig. 101). Epiproct elongate, narrow, deeply furrowed. Paraproct with compressed triangular projection. Cerci cylindrical, slightly curved, with three internal projections: two in middle, one at apex; of the former the ventral little closer to base than the dorsal (Figs. 136, 176, 205, 235). Dorso-internal projection compressed, triangular; ventro-internal projection small, digitiform. Apico-internal projection long, compressed, with obtuse apex. Subgenital plate at apex roundly excised (Fig. 283). Titillators separate; basal parts rather broad, little twisted, simple; apical parts roughly triangular with rounded angles. Surface of apical parts densely covered with clinging hairs; apico-lateral margin substraight, angles rounded, coarsely granular (Figs. 310, 354, 398). Baso-lateral sclerite curved with quadrangular hyaline appendage. Apico-lateral sclerites large, oval, hyaline. Female. Tenth abdominal tergite furrowed in midline. Epiproct triangular with apex obtuse; dorsally furrowed. Subgenital plate divided in midline by membranous area; lateral plates with a strong obtuse carina running laterad and covering apico-lateral margin of sclerite in ventral view; with groove at base; internal margin concave, apex truncate (Figs. 453, 501, 533). <b>Coloration.</b> Yellowish brown. Face with black band between eyes including scapus, less distinct on genae; with a black band along clypeo-frontal suture extended on genae. Pronotum yellowish brown; disc darkened especially in fore and hind areas, interrupted by yellowish brown round marks. Tegmen with dark cells and light veinlets. <b>Measurements</b> (1 male, 2 females): body male 30, female 30; pronotum male 7.5, female 7.5; tegmen male 27, female 27.5–28.0; hind femur male 18, female 18–20; ovipositor female 16.5–17.0 mm. <b>Etymology.</b> Named for the shape of the apical tooth of the male cerci; noun in apposition.
