description: <i>Pseudonicsara (P.) cervus</i> sp. n. Figs. 73, 115, 156, 193, 225–226, 248, 276, 326, 372, 390, 411, 471, 510, 522, map 3. Holotype (male): Papua New Guinea: Madang Dist., Kairong area [3° 58' S, 143° 56' E], XII.1971 – I.1972, J. Menzas, depository: Collectio Fer Willemse, Eygelshoven, Netherlands (CW), later to be deposited in Naturalis, Leiden (RMNH). Paratypes: 3 females, same data as holotype (CW). <b>Diagnosis.</b> The new species shares with <i>P. forceps</i> that the male cerci have two apico-internal processes, of which one lies nearly in the prolongation of the cercus. <i>P. cervus</i> differs by having the dorsal apico-internal process in prolongation of cercus, which is curved and has the apex obtuse triangular; the ventral process is compressed and has the apex rounded (Figs. 115, 193). It also differs in having two baso-internal processes of the cercus and by the titillators being short with the apical margin protruding on both sides (Figs. 372, 390). The female subgenital plate has a deep median furrow and a pair of large lateral grooves covering most of the plate; the dorso-lateral-apical angles are little acute angularly projecting (Figs. 471, 510). Differences to other species are outlined in the key. <b>Description.</b> Fastigium verticis in front of eyes 0.9 mm, from base 1.2 mm; dorsal eye length 1.4 mm; greatest diameter of eye 1.6 mm; index fastigium verticis from base: eye length 0.8. Face shining with large but shallowly impressed dots in middle, almost smooth lateral, rugose again towards genae. Pronotum shining. Tegmen little surpassing hind knees; rather wide at base, apical half narrow. Femora with the following number of spines on ventral margins: fore femur 6–8 external, 6 internal; mid femur 6 external, 3 internal near base; hind femur 7–9 external, 0–2 minute internal spines in basal area. Male. Stridulatory file slightly sinuate, 2.0 mm long; teeth at apex very dense and indistinct [70 distinct and 40 indistinct teeth in apical area], together with 110 teeth or 53.8 teeth per mm, in middle of file with 29.5 teeth per mm (Fig. 73). Mirror little widening anteriorly; apical margin substraight; 1.4 mm long, 1.2 mm wide; index length:width = 1.2. Tenth abdominal tergite transverse but globular in middle; apical margin broad-roundly excised between two short, obtuse, projecting lobes (Fig. 115). Epiproct acute triangular with lateral margins upcurved, in apical half deeply furrowed in midline (Fig. 156). Projection of paraproct short, transverse, obtuse, dorso-ventrally compressed. Cerci conical, apical third dorso-ventrally compressed, curved mediad, terminating in a triangular flap; internal surface with a greatly projecting rim over almost whole cercus length running at proximal end into a compressed projection pointing mediad, carrying a minute spinule on tip, at distal end with a compressed projection, which is slightly twisted and pointing ventrad, with apex obtuse; below projecting rim internal surface with another small projection (Figs. 193, 225–226, 248). Subgenital plate wider than long with apical excision wide and shallow (Fig. 276). Titillators with basal parts broad, simple; apical parts widening towards apex; internal surface with clinging hairs; margin granular, irregularly sinuate (Figs. 326, 372, 390, 411). Female. Tenth abdominal tergite transverse, apex triangularly excised in middle. Subgenital plate with a deep and wide median furrow, sclerites on both sides of furrow with elevated margins and deeply depressed surface; apex with a triangular projection at both lateral angles and widely excised in between; dorso-lateral of lateral margins with a large rounded lateral sclerite at each side (Figs. 471, 510, 522). <b>Coloration.</b> Uniformly yellowish brown. Face with a blackish brown vertical band from fastigium frontis to dorsal area of clypeus, widening ventrad to a transverse band along clypeo-frontal suture; median ocellus light; antennal scrobae, ventral surface of scapus and apex of mandibles also blackish brown. Tegmen with yellow or white veins and brown cells. Legs ochre (green when alive?); hind knees brown. Fore tibia with dorsal areas slightly infumate. <b>Measurements</b> (1 male, 3 females): body: male 24, female 24–27; pronotum: male 6.5, female 6.7–7.2; tegmen: male 22, female 24–26; hind femur: male 14, female 15–18; ovipositor: 15–16.5 mm. <b>Etymology.</b> Named for the horn-shaped male cercus; noun in apposition.
