Diagnosis. Clistopyga catarina sp. nov. may be distinguished from all other species of the C. eldae species group by the combination of the following characters: hind wing with distal abscissa of Cu 1 strong and pigmented, joining cu -a + Cu 1 at centre (Fig. 3B); tergite I and II smooth and shiny, with scattered setiferous punctures (Fig. 2B). Female with ovipositor bent up at distal 0.5 (Fig. 5E), 1.25–1.28× as long as hind tibia; ovipositor sheath 1.0– 1.11× as long as hind tibia. Male with lower part of gena deeply concave, hypostomal carina conspicuously developed as a translucent sheet (Fig. 10A).
Description. Female: Body length 8.6–9.3 (without ovipositor). Fore wing length 6.2–6.6 mm.
Head (Figs 5 A–D). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view straight 0.27–0.3× as long as eye (Fig. 5C), in frontal view straight and strongly constricted below eyes (Fig. 5B). Frons smooth and shiny. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 0.8–0.9× its maximum diameter. Distance between hind ocelli 0.6–0.73× maximum diameter of posterior ocellus. Occipital carina complete (Fig. 5A) Face with fine and dense setiferous punctures, distance between punctures more than three times the diameter of punctures. Clypeal suture slightly curved (Fig. 5B). Clypeus 1.73–2.2× as broad as medially long, weakly convex, with apical margin straight. Malar space 0.37–0.45× as long as basal mandibular width, with a weakly wide granulate stripe between eye and mandible. Antenna with 31 flagellomeres, first flagellomere 8.3–8.8× as long as wide.
Mesosoma (Figs 3B, 4B, 5C, D). Pronotum smooth and shiny. Epomia absent (Fig. 5D). Mesoscutum smooth and shiny, with very fine and moderately dense setiferous punctures (Fig. 5C). Notauli weak, reaching about 0.5 of length of mesoscutum. Mesopleuron shiny, with moderately sparse setiferous punctures, except in posterior part under speculum. Epicnemial carina weak, its dorsal end straight, reaching level of centre of pronotum. Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior part, 1.9–2.1× as long as deep. Submetapleural carina strong and complete (Fig. 4B). Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally, in dorsal view 1.0–1.16× as long as medially wide. Propodeal spiracle at groove separating propodeum and metapleuron, groove interrupted by spiracle. Hind leg with femur 4.3–4.6× as long as deep, 0.85–0.91× as long as tibia. Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m 0.6–0.95× 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 0.85–1.15× as long as Cu 1 b. Hind wing with vein cu-a 0.95–1.0× as long as abscissa of Cu 1 between M and cu-a. Vein cu-a reclivous, first abscissa of Cu 1 vertical. Distal abscissa of Cu 1 well pigmented (Fig. 3B).
Metasoma (Figs 2B, 5 E–F). Tergite I 1.64–1.76× as long as posteriorly broad, smooth and shiny, with fine and relatively dense setiferous punctures laterally (Fig. 2B); spiracle near its basal 0.35; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carinae weak, reaching about 0.2 of length of tergite. Sternite I extending back about 0.75 of length of tergite (Fig. 5E). Tergite II 1.00–1.18× as long as posteriorly broad, central region shiny, with fine and sparse setiferous punctures (Figs 2B, 5F); rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor slender, matt, bent up at distal half (Fig. 5E), 1.25–1.28× as long as hind tibia. Ovipositor sheath 1.03–1.11× as long as hind tibia, length of setae on average 1.8– 2.4× the sheath basal width.
Colouration (Figs 1B, 5 A–F). Head black with clypeus, face, frontal and vertical orbits, mouth parts except apex of mandibles, malar space and ventral part of gena, white; antenna with scape and pedicel dark brown dorsally, widely white at ventral side, flagellomeres brown, basal flagellomeres whitish on the ventral side. Mesosoma mostly orange, propleuron and postscutellum, white; posterolateral corners of propodeum and posterior part of metapleuron and posterior lower part of mesopleuron sometimes paler; metapleuron with a wide dark brown mark; posterior dorsal part of propodeum brown, posterior rim of propodeum black. Metasoma mostly dark brown, anterolateral marks of tergites I–VI, somewhat extending back, anterior narrow band of tergites III–VI and posterior rim of tergites II–VII, whitish. Legs predominantly white; mid leg with anterior and posterior basal marks on trochanter, dorsal narrow stripe on femur and dorsal basal and distal part of tibia, brown, tarsi infuscate; hind leg with anterior wide mark on coxa, anterior and posterior basal marks on trochanter, basal part, dorsal stripe and anterior subapical marks on femur, tibia except mid part, and all tarsi, brown.
