description: <i>Pseudonicsara (P.) bitriangulata</i> sp. n. Figs. 88, 121, 185–186, 239, 273, 423–424, 469–470, map 3. Holotype (male): Indonesia, Papua: North New Guinea Exped., Mamberamo, Alb-Bivak [Albatros Bivak 2° 17' S, 138° 01' E], V.1926, W. Docters v. Leeuwen, labelled: " <i>Pseudonicsara? bitriangulata</i> <b>sp. n.</b> ", depository: Museum Zoologicum Bogoriense, Cibinong, Indonesia (MBBJ). Paratypes: 2 females, same data as holotype (MBBJ). <b>Diagnosis.</b> Males of the new species differ from other species of <i>Pseudonicsara</i> s. str. by the deep excision of the tenth abdominal tergite (Fig. 121) and the characteristic shape of the cerci, which have a triangular ventral apico-internal process, a dorsal apico-internal process only indicated by a short cone, and two baso-internal processes, the dorsal process compressed triangular, the ventral elongate conical (Figs. 185– 186, 239). Females are characterised by the subgenital plate that is completely divided in midline into two angular plates (Figs. 469–470). <b>Description.</b> Fastigium verticis in front of eyes 1,12 mm, from base 1,63 mm; dorsal eye length 1,7 mm; index fastigium verticis from base: eye length 0,96. Face rugose. Tegmen rather narrow, surpassing hind knees. Femora with the following number of spines on ventral margins: fore femur 7–8 external, 6 internal; mid femur 6 external, 3 internal near base; hind femur 8–11 external, 4–7 internal near base. Male. Stridulatory file with circa 123 teeth (Fig. 88). Tenth tergite with apex fissing in midline to nearly base (Fig. 121). Epiproct long with parallel lateral margins and convex apex, dorsally furrowed (Fig. 121). Cerci narrow-cylindrical, slightly curved with three internal processes: two of them compressed and circa triangular, one about in middle and one just before apex of cercus, the latter with an angular fold at base; third process finger-shaped, inserted ventro-apical of first projection (Figs. 185–186, 239). Subgenital plate with styli very thin, inserted on ventral surface (Fig. 273). Titillators with basal parts fused and hyaline [because freshly moulted?]; apical parts free [not fully sclerotised by the time of collecting], circa ovoid, surface covered with clinging hairs, dark in centre, pale towards margins; margin coarsely granular with a transverse crest near apex (Figs. 423–424). Female. Subgenital plate with central area membranous and an angular, sclerotised plate at each side with concavely depressed surface and broad bulging margin (Figs. 469–470). <b>Coloration.</b> Brown (partly green when alive?). Face yellowish-brown, with or without an inverse Yshaped green band from fastigium frontis to clypeo-frontal suture; area around clypeo-frontal suture with a large black spot; labrum yellow; mandibles dark brown and black towards apex; antennal scrobae and area below and between them and ventral surfaces of scapus and pedicellus dark brown, median ocellus yellow. Pronotum brown with pale spots, in 1 male with a green band at anterior and ventral margins. Femora brown (partly green when alive?), darkened at knees; tibiae and tarsi darkened or not; spines dark brown. Tegmen dark brown with veins (except radius) and part of transverse veinlets yellow. Antennae medium brown. <b>Measurements</b> (1 male, 2 females): body male 30, female 29–32; pronotum male 8.5, female 9.0; tegmen male 31, female 31–32; hind femur male 20, female 21; ovipositor 20–21. <b>Etymology.</b> Named for the male cerci carrying two compressed triangular processes.
