Diagnosis

Clistopyga cinnamoptera sp. nov. can be distinguished from all other species of the C. chaconi species group by the combination of the following characters: wings moderately infuscate, except in a broad hyaline band bordering veins Rs +2 r, 2 rs-m and 2 m-cu of fore wing (Fig. 1B); ovipositor stout, weakly upcurved in apical 0.5 ( Fig. 2 F), about 1.25 times as long as hind tibia; first flagellomere about 4.8 times as long as wide; setae of ovipositor sheath, on average, about 1.8 times the sheath basal width ( Fig. 2 F); tergite I 2.3 times as long as broad ( Fig. 2 D); occipital carina weakly raised, forming a flat flange dorsomedially ( Fig. 2 B); malar space 1.0 times as long as basal mandibular width.

Etymology

The name of the species refers to the infuscate wings.

Description

Female

MEASUREMENTS. Body length 7 mm. Fore wing length 6 mm

HEAD. In dorsal view, strongly narrowed behind eyes.Gena smooth and shiny, with very sparse, moderately long setae ventrally, in dorsal view 0.35 times as long as eye, in frontal view slightly rounded 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 by about 1.1 times its maximum diameter. Distance between hind ocelli about 1.0 times maximum diameter of posterior ocellus. Occipital carina weakly raised, forming a flat flange dorsomedially ( Fig. 2 B). Face with shallow and dense setiferous punctures, distance between punctures less than twice diameter of punctures. Clypeal suture slightly curved. Clypeus about 1.6 times as broad as medially long, weakly convex in dorsal half, slightly concave in ventral half, with apical margin truncate. Malar space 1.0 times as long as basal mandibular width, with deep and narrow, smooth and shiny sulcus between eye and mandible. Antenna with 31 flagellomeres, first flagellomere about 4.8 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 terminating 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 about 1.15 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, 0.90 times as long as tibia. Fore wing with vein cu-a opossite 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 1.65 times as long as Cu 1b. Hind wing with vein cu-a about 0.6 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 strongly reclivous. Vein Cu 1 distinctly pigmented.

METASOMA. Tergite I about 2.3 times as long as posteriorly broad, smooth and shiny, with very fine and sparse setiferous punctures laterally and posteriorly; spiracle near its basal 0.35; lateromedian longitudinal carinae strong, reaching about 0.1 of length of tergite ( Fig. 2 D); lateral longitudinal carina absent. 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 moderately sparse puctures; rest of tergites shiny, more densely punctate. Ovipositor stout, weakly upcurved in apical 0.5, matt ( Fig. 2 F), 1.25 times as long as hind tibia. Ovipositor sheath about 1.0 times as long as hind tibia, length of setae on average about 1.8 times the sheath basal width ( Fig. 2 F).

COLOURATION. Body primarily orange, dark brown and white (Fig. 1B). Antenna light brown, pallid towards base of the external side including pedicel and apical part of scape. Head dark brown to black with upper part of clypeus, ventral part of gena, inner eye orbit (except an interruption at vertex), two longitudinal blotches on face and one transverse blotch under antennal sockets yellow. Palpi light orange. Mesosoma entirely orange except black dorsal hind border of propodeum, ventral part of metapleuron, propleuron, posterior part of mesosternum and metasternum strongly infuscate. Tegula light orange. Wings moderately infuscate, except in a broad hyaline band bordering veins Rs +2 r, 2 rs-m and 2 m-cu of fore wing. Fore leg mostly light brown, with coxa infuscate. Mid leg with coxa, trochanter, trochantellus and distal parts of tarsomeres dark brown, femur, tibia and basal part of tarsomeres light brown. Hind leg mostly dark brown, with dorsal part of coxa, apical band on femur, mid band of tibia and proximal parts of tarsi white. Metasoma dark brown, with posterior margins of tergites I–VII white, posterior corners of tergites II–III with black spots; tergites IV–VI with the dark brown area extending laterally backward. Ovipositor dark brown. Ovipositor sheath black.
