(Figs 1, 3 A–F, 7A, 8A, 9C)
Diagnosis. Clistopyga carinata sp. nov. can be easily distinguished from all other Neotropical species of the C. henryi species group by the evenly down-curved ovipositor at distal 0.4 (Figs 1, 3D); submetapleural carina strong and complete (Fig. 7A); hind wing with distal abscissa of Cu 1 well pigmented; metapleuron and propodeum mostly reddish-orange (Fig. 3B); tergites II to VIII predominantly dark brown (Figs 3C, F).
Description. Female: Body length 9.3 mm. Fore wing length 6.7 mm.
Head (Figs 3A, B, E). In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny with evenly sparse setiferous punctures, in dorsal view 0.18× as long as eye, in frontal view slightly concave and constricted below eyes (Fig. 3A). Frons smooth and shiny. Vertex smooth and shiny, with isolated setiferous punctures. Posterior ocellus separated from eye about once its maximum diameter, distance between hind ocelli about 1.18× its maximum diameter of posterior ocellus. Occipital carina, weak but complete, not raised in a flange-like protuberance at the lower lateral region of head. Face with fine and relatively scattered setiferous punctures, distance between punctures much more than twice the diameter of punctures. Clypeal suture slightly curved. Clypeus 1.6× as broad as medially long, moderately convex in dorsal half, flat in ventral half, with apical margin straight (Fig. 3A). Malar space about 0.66× as long as basal mandibular width, with a granulate wide sulcus. Antenna with 26 flagellomeres, first flagellomere about 9.0× as long as wide.
Mesosoma (Figs 3B, E, 7A). Pronotum shiny, mostly smooth, with fine and scattered setiferous punctures in upper posterior part. Mesoscutum entirely smooth and shiny, with fine and sparse setiferous punctures (Fig. 3B, E). Notauli deep, reaching about 0.4 of length of mesoscutum (Fig. 3E). Mesopleuron shiny, with very sparse setiferous punctures, except in posterior part below speculum. Subalar prominence with 7–9 setiferous punctures. Epicnemial carina weak, its dorsal end slightly curved backward, ending at level of centre of pronotum. Metapleuron shiny, almost glabrous, except for some sparse setiferous punctures at posterior part, 1.81× as long as deep. Submetapleural carina strong and complete (Fig. 7A). Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally, in dorsal view 0.92× as long as medially wide. Propodeal spiracle joining groove separating propodeum and metapleuron, groove partially interrupted by spiracle (Fig. 3B). Hind leg with femur about 4.55× as long as deep and about 0.93× as long as tibia.
Wings. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m about 0.33× as long as abscissa of M between 2 rs-m and 2 m-cu; abscissa of Cu 1 between 1 m-cu and Cu 1 a about 1.58× as long as Cu 1 b. Hind wing with vein cu- a about 0.67× as long as abscissa of Cu 1 between M and cu-a; vein cu-a reclivous; abscissa of Cu 1 vertical and straight; distal abscissa of Cu 1 well pigmented.
Metasoma (Figs 3C, D, F, 8A). Tergite I 1.33× as long as posteriorly broad, smooth and shiny (Fig. 8A), with fine and relatively dense setiferous punctures laterally; spiracle near its basal 0.4; lateromedian longitudinal carinae weak, reaching about 0.3 of length of tergite; lateral longitudinal carinae weak, reaching about 0.2 of length of tergite. Sternite I extending back about 0.4 of length of tergite. Tergite II 1.05× as long as posteriorly broad, central region shiny, with very fine and sparse setiferous punctures; lateral part weakly rugulose, rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor slender, evenly down-curved at distal 0.4 (Fig. 3D), about 2.66× as long as hind tibia. Ovipositor sheath about 2.3× as long as hind tibia, length of setae on average about 2.0× the sheath basal width.
Colouration. Head black with clypeus, facial, frontal and vertical orbits, face except a small central brownish hue, mouth parts except apex of mandibles, malar space except sulcus, and subventral mark at posterior orbits, white (Figs 3A, B, E); antenna with scape and pedicel black dorsally, widely white at ventral side, flagellomeres brown, the basal ones pallid on the ventral side. Mesosoma mostly reddish-orange, upper anterior corner and anterior margin of pronotum, propleuron ventrally, almost entirely posterior rim of mesopleuron, tegula, scutellum posteriorly, metanotum dorsally, posterodorsal corners of propodeum and weak posterior marks of metapleuron, white; metapleural carina and posterior rim of propodeum black (Figs 3B, E). Metasoma mostly dark brown, with transverse white bands on tergites I to VI and whitish small areas on anterolateral corners of tergites I to III; tergites II to VI with posterolateral black to blackish spots posterior to transverse white bands (Figs 3C, F). Legs predominantly whitish; fore leg with dorsal and ventral stripes on femur and tibia, and all tarsi, brown; mid leg with apical dorsal mark on coxa, basal part of trochanter, dorsal and ventral stripes on femur and tibia, and all tarsi, brown; hind leg with dorsal, anterior and posterior stripes on coxa, basal part of trochanter basal part, dorsal and anterior strip on femur, tibia except mid dorsal part, and all tarsi, brown. Wings hyaline, pterostigma brown. Ovipositor sheaths dark brown. Ovipositor reddish-brown.
Male: unknown.
Etymology: The specific name refers to the distinctly strong and complete submetapleural carina.
