PAPUAONTSIRA n. gen.

Type species. Papuaontsira villemantae n. sp.

ETYMOLOGY — From combination of the name of the country where this genus was collected and the name of morphologically similar genus Ontsira .

DISTRIBUTION — Australasian region.

COMPARATIVE DIAGNOSIS — This new genus is similar to Ontsira Cameron , but distinctly differs from it in having the labial palpus with three segments, brachial vein (CU1b) of fore wing distinctly inclivous (directed towards base of wing), nervulus (cu-a) of fore wing antefurcal, submedial (subbasal) cell of hind wing short, and propodeum without areas delineated by carinae.

DESCRIPTION — Head transverse (Figure 2) and not depressed (Figure 3). Vertex without transverse ridges at ocelli level. Ocelli arranged in obtuse triangle with base larger than sides (Figure 2). Frons almost flat, without median longitudinal carina and furrow. Eyes glabrous. Furrow or carina between antennal socket and inner margin of eye absent. Occipital carina dorsally complete, joining hypostomal carina above base of mandible. Malar suture present, wide but shallow. Clypeus almost flat, with short lower flange. Clypeal suture complete, rather deep and narrow. Hypoclypeal depression medium sized and rounded (Figure 3). Postgenal bridge narrow. Maxillary palpus long, 6-segmented, its sixth (apical) segment about as long as fifth segment; labial palpus short, 3-segmented. Scape of antenna (Figure 4) narrow and long, with short apical lobe below, without basal constriction, its ventral margin (lateral view) slightly shorter than dorsal margin. First flagellar segment almost straight, round in dissection, slightly longer than second segment. Apical segment distinctly pointed apically, but without spine (Figure 5). Mesosoma (Figure 6) not depressed and of medium length. Neck of prothorax short. Pronotum dorsally weakly convex, without lobe, anterior flange of pronotum short and slightly curved up; pronotal submedian carina present, fine. Pronope absent (Figure 7). Propleural dorsoposterior flange short, wide. Mesonotum highly and roundly elevated above pronotum (Figure 6). Median lobe of mesonotum without median furrow and pointed anterolateral corner. Notauli deep in anterior half, shallow to very shallow in posterior half, almost incomplete, narrow (Figure 7). Tegula widened distally, weakly convex along posterior margin. Prescutellar depression long, with distinct median carina. Lateral longitudinal wing-like flanges on level of prescutellar depression low, but distinct. Scuto-scutellar suture distinct, complete. Scutellum weakly convex, without lateral carinae (Figure 7). Subalar depression shallow and rather narrow. Mesopleural pit shallow, small, oval, virtually not connected with mesopleural furrow. Precoxal sulcus (sternaulus) shallow, wide, short (incomplete), straight, smooth (Figure 6). Prepectal carina distinct and complete, laterally following upper margin of precoxal sulcus. Postpectal carina absent. Metanotum without median tooth (lateral view). Metapleural flange short, wide, rounded. Propodeum (Figure 8) without areas delineated by carinae; lateral tubercles absent; propodeal bridge absent. Propodeal spiracles small and subcircular. Metapleural suture with carina. Metapleuron weakly convex. Wings (Figures 12, 13). Pterostigma of fore wing rather wide. Radial vein (r) arising slightly behind middle of pterostigma. Radial (marginal) cell elongate. Both radiomedial veins (2-SR and r-m) present. Second radiomedial (submarginal) cell short and rather wide. Recurrent vein (m-cu) distinctly antefurcal. Discoidal (first discal) cell petiolate anteriorly, petiole (1-SR) long. Nervulus (cu-a) antefurcal. Parallel vein (CU1a) arising from posterior 0.25 of apical margin (3-CU1) of brachial (first subdiscal) cell. Brachial (first subdiscal) cell closed postero-apically by declivous brachial vein (CU1b) (Figure 13). Transverse anal veins (2A, 1A) absent. Hind wing with three hamuli. First abscissa of costal vein (C+SC+R) 0.85 times as long as second abscissa (1+SC+R); first abscissa (C+SC+R) not divided apically on two absissae. Radial vein (SR) arising from costal vein (2+SC+R) closely to basal vein (1r-m). Radial (marginal) cell weakly narrowed towards apex, without transverse vein (r). Medial (basal) cell weakly widened towards apex, about 10.0 times longer than width, about 0.4 times as long as hind wing. Nervellus (cu-a) present. Submedial (subbasal) cell short. Recurrent vein (m-cu) long, distinctly oblique toward base of wing, almost straight. Legs. Fore tibia on inner surface with numerous, long, slender and dense spines arranged in wide vertical stripe. Fore tarsus short, 1.3 times longer than fore tibia. Middle tibia with numerous slender spines on lateral surface. Middle tarsal segments rather long. Hind coxa (Figure 9) short, wide, with basoventral corner toothed, without dorsal tooth or tubercle. Hind femur (Figure 10) without dorsal protuberance, wide. Tibial spurs straight, short, rather slender. Basitarsus of hind tarsus 0.7 times as long as second-fifth segments combined. Claws enlarged, simple, distinctly widened basally. Metasoma (Figures 8, 15, 16). First tergite (Figure 8) sessile, short and

wide. Acrosternite of first segment short, about 0.25 times as long as first tergite, its hind margin not reaching level of

spiracles (Figure 16). Dorsope of first tergite deep and wide; basolateral lobes very short; spiracular tubercles absent, spiracles situated in basal 0.3 of tergite; dorsal carinae distinct, complete, subparallel medially and weakly converging apically, not reaching apex of tergite (Figure 8). Second tergite basally with narrow and semi-rounded smooth area separated posteriorly from remainder of tergite by coarse sculpture only (not by furrow) (Figures 8, 15). Suture between second and third tergites deep, rather wide, weakly sinuate (Figure 15). Third tergite with distinct transverse straight and complete furrow in basal 0.3 (Figure 15). Remaining tergites without basal transverse furrows. Second to fifth tergites with separate laterotergites (Figure 16). Third to sixth tergites dorsally without any setae. Hypopygium in apical margin obtuse, without pointed median corner. Ovipositor apically straight, with two obtuse but distinct dorsal nodes (Figure 14). Ovipositor sheath shorter than metasoma.
