description: <i>Habetia elevata</i> sp. nov. Figs 2C, 6J, 7L– <b>M</b>, Map 1(18). <b>Holotype (female):</b> Papua New Guinea: Morobe, 25 km South of Salamaua, elev. 1–80 m (7°13’S, 147°7’E), 25–26.i.1969, leg. J. Sedlacek —depository: Bernice B. Bishop Museum, Honolulu (BPBM). <b>Diagnosis.</b> A rather stout and compact species compared to the other species of the genus. Wings surpassing hind knees. The species is unique for the shape of the female subgenital plate that has the dorso-lateral projections strongly prolonged on basal side and the apical area is, in lateral view, hidden between the projecting lateral surfaces. In strict lateral view it thus appears that the subgenital plate is becoming wider toward tip (Fig. 7M) while in the other species it is becoming narrower and terminates into a pair of narrow projections. In ventro-apical view the plate has a rectangular frame in center with bi-triangular apical margin, while the lateral areas are strongly stretching dorso-laterad. <i>H. elevata</i> <b>sp. nov.</b> is also striking for the large excavation of the eight abdominal tergite from the ventro-posterior angle, leaving only a narrow, sclerotized band along the anterior margin while the dorsal area of the tergite is normal; the rim of the tergite around the excavation is strengthened and little projecting; that space provides room for articulation of the baso-lateral extensions of the subgenital plate and the base of the ventral ovipositor valves. <b>Description.</b> Coloration of face uniformly pale, of general color, mandibles black. Femora with the following number of spines on ventral margins: (1) a 6, p 7–8; (2) a 6–7, p 3; (3) a 15–16, p 16. Male unknown. Female. Eighth abdominal tergite with a large membranous convexity at latero-posterior angle providing room for base of subgenital plate and ventral ovipositor valves. The narrow lateral expansions of the subgenital plate appear in lateral view to be squeezed between the long and narrow membranous area at base of the ventral ovipositor valve and the eight abdominal sternite; the ventral margin with a small sub-basal convexity otherwise reflect the modifications of the ventral surface (Fig. 7M). Subgenital plate in ventral view sub-triangular with concave basal margin and strongly converging lateral margins, concave near base, convex thereafter; behind about basal third in middle of plate with elevated ridges forming a rectangular elevation with straight basal and lateral margins that embrace a depression; that structure surpasses the converging lateral margins of the plate and terminates into a pair of triangular extensions with less elevated rims; baso-laterally of that structure there is a pair of short and stout curved ridges (Fig. 6J). In lateral view, the dorsal margin of the subgenital plate appears nearly straight. The apical area is hidden between the projecting apical margins of the rectangular elevation, while the ventral margin reflects the sculptured ventral surface of the plate (Figs 7L–M). Ovipositor little shorter than body in the single female at hand; behind basal constriction dorsal margin convex, strongly elevated to about mid-length, then narrowing again towards sub-obtuse tip (Fig. 2C). Measurements (1 female).—Body w/wings: 56; body w/o wings: 47; pronotum: 10; tegmen: 40; hind femur: 27; ovipositor length: 32; ovipositor greatest height: 4.5 mm. <b>Etymology.</b> The name of the new species refers to the shape of the ovipositor that is markedly elevated around mid-length, from Latin <i>elevata</i> = to elevate, elevated.
