Diagnosis

Clistopyga melanoptera sp. nov. can be distinguished from all other species of the C. chaconi species group by the combination of the following characters: wings strongly infuscate, except in a broad hyaline band bordering veins Rs +2 r, 2 rs-m and 2 m-cu of fore wing (Fig. 1C); ovipositor slender, strongly upcurved at distal 0.45, about 1.4 times as long as hind tibia (Figs 1C, 2E); first flagellomere about 6.0 times as long as wide; setae of ovipositor sheath, on average, about 1.35 times the sheath basal width ( Fig. 2 E); tergite I twice as long as posteriorly broad ( Fig. 2 C); occipital carina strongly raised, forming a dorsomedial flange, conspicuously upcurved posteriorly ( Fig. 2 A); malar space 0.8 times as long as basal mandibular width.

Etymology

The name refers to the dark wings of the new species.

Description

Female

MEASUREMENTS. Body length 11 mm. Fore wing length 8 mm.

HEAD. In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny, with sparse, moderately long setae ventrally, in dorsal view about 0.4 times as long as eye, in frontal view straight and moderately constricted below eyes. Frons smooth and shiny, with a weak medial longitudinal depression. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye about 1.0 times its maximum diameter. Distance between hind ocelli about 0.9 times maximum diameter of posterior ocellus. Occipital carina strongly raised and forming a dorsomedial flange, conspicuously upcurved posteriorly ( Fig. 2 A). Face with fine and dense setiferous punctures, distance between punctures about diameter of punctures. Clypeal suture slightly curved. Clypeus 1.65 times as broad as medially long, weakly convex in dorsal half, flat in ventral half, with apical margin slightly rounded. Malar space 0.8 times as long as basal mandibular width, with deep and narrow granulate sulcus between eye and mandible. Antenna broken in unique holotype, with 14+ flagellomeres, first flagellomere about 6.0 times as long as wide.

MESOSOMA. Pronotum shiny, mostly smooth, with fine and sparse setiferous punctures in upper posterior part. Mesoscutum entirely smooth and shiny, median lobe anteriorly with very fine shallow and sparse setiferous punctures. Notauli weak, reaching about 0.4 of length of mesoscutum. Mesopleuron shiny, mostly smooth, with very sparse and fine setiferous punctures except in dorsal posterior part. Epicnemial carina very weak, its dorsal end ending far from anterior margin of mesopleuron, considerably below level of centre of pronotum. Metapleuron smooth and shiny, with fine and sparse setiferous punctures, about 1.9 times as long as deep. Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally; in dorsal view 1.16 times as long as medially wide. Propodeal spiracle situated immediately above groove separating propodeum and metapleuron. Hind leg with femur 3.85 times as long as deep, about 0.9 times as long as tibia. Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m longer than half length of abscissa of M between 2 rs-m and 2 m-cu. Abscissa of Cu 1 between 1 m-cu and Cu 1a about 2.35 times as long as Cu 1b. Hind wing with vein cu-a 0.52 times as long as abscissa of Cu 1 between M and cu-a. Vein cu-a + abscissa of Cu 1 between M and cu-a slightly reclivous. Vein Cu 1 distinctly pigmented.

METASOMA. Tergite I about twice as long as posteriorly broad, smooth and shiny, with very fine, relatively dense setiferous punctures laterally and posteriorly; spiracle near its basal 0.4; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carina absent ( Fig. 2 C). Sternite I extending back about 0.6 of length of tergite. Tergite II 1.35 times as long as posteriorly broad, central region shiny, with shallow and dense punctures, rest of tergites shiny, more densely punctate. Ovipositor slender, strongly upcurved at distal 0.45, matt, about 1.4 times as long as hind tibia (Figs 1C, 2E). Ovipositor sheath about 1.1 times as long as hind tibia, length of setae on average about 1.3 times sheath basal width ( Fig. 2 E).

COLOURATION. Body primarily orange, black and white (Fig. 1C). Antenna brownish, pallid towards base of external side including pedicel and distal rim of scape. Head black with upper part of clypeus, base of mandible, ventral part of gena, inner eye orbit (except an interruption at vertex), two longitudinal rectangular blotches on face and two transverse blotches under antennal sockets yellow. Palpi orange. Mesosoma entirely orange except dorsal posterior border of propodeum black. Tegula orange. Wings strongly infuscate except in a broad hyaline band bordering veins Rs + 2r, 2 rs-m and 2 m-cu of fore wing. Pterostigma dark brown. Fore legs orange, mid leg mostly orange, with ventral part of coxa, posterior part of trochanter and basal posterior part of femur dark brown to black. Hind leg black, with dorsal band on coxa, a not delineated mark on mid dorsal part of femur, a partial band in middle of tibia and proximal part of tarsomeres yellowish. Metasoma black, anterior part of tergite I yellow and orange, posterior band of tergites I–VII white. Posterior corners of tergites II–III with black spots. Ovipositor dark brown. Ovipositor sheath black.

Male

Unknown.
