Diagnosis. Clistopyga diazi may be distinguished from all other species of the C. diazi species group by the combination of the following characters: mesosoma extensively reddish ( Figs 4 A–B, 4D); genal orbit widely black, with a triangular white mark at ventral third ( Fig. 4A ); lateral part of pronotum black, only yellow-banded dorsally; propodeum dorsally black, laterally white ( Fig. 4D ); hind leg with coxa and femur black, widely white coloured; clypeal suture strongly curved ( Fig. 4C ); metapleuron about 2.23× as long as high ( Fig. 4D ); submetapleural carina present at anterior 0.45 ( Fig. 2B ); tergite I and II about 1.3× and 0.9× as long as wide respectively; ovipositor and ovipositor sheath about 2.1× and 1.75× as long as hind tibia respectively ( Fig. 4F ).

Description. Female: Body length about 10.8 mm (without ovipositor). Fore wing length about 7.9 mm.

Head ( Figs. 4 A–C). In dorsal view, moderately narrowed behind eyes ( Fig. 4B ). Gena smooth and shiny with evenly sparse setiferous punctures, in dorsal view 0.45× as long as eye, in frontal view slightly concave and moderately constricted below eyes. Frons and vertex smooth and shiny, with sparse setiferous punctures. Posterior ocellus separated from eye 1.4× its maximum diameter, distance between hind ocelli about 1.07× its maximum diameter of posterior ocellus. Occipital carina, strong and complete ( Fig. 4A ). Face with fine and moderately scattered setiferous punctures, distance between punctures in lateral part more than three times their diameter, central part more densely punctate. Clypeal suture strongly curved ( Fig. 4C ). Clypeus about 1.5× as broad as medially long, almost flat, with apical margin straight. Clypeal tentorial pits conspicuous. Malar space about 1.1× as long as basal mandibular width, with a slightly granulate very narrow sulcus. Antennae broken, the longer with 16 flagellomeres, first flagellomere about 8.0× as long as wide.

Mesosoma ( Figs 2B , 4 A–B, 4D). Pronotum shiny, with fine and scattered setiferous punctures on upper posterior part. Epomia absent. Mesoscutum shiny, with moderately dense setiferous punctures. Notauli deep, reaching about 0.6 of length of mesoscutum ( Fig. 4B ). Mesopleuron shiny, with relatively dense setiferous punctures separated 3–5 times their diameters, except in posterior part below speculum ( Fig. 4A ). Epicnemial carina weak, its dorsal end slightly curved backwards, reaching a little below centre of pronotum. Metapleuron shiny, almost glabrous, except for some setiferous punctures at posterior part, about 2.23× as long as high. Submetapleural carina present at anterior 0.45 ( Fig. 2B ). Propodeum with fine and dense transverse striae, with sparse and fine setiferous punctures laterally ( Fig. 4D ), in dorsal view 1.4× as long as medially wide. Propodeal spiracle at groove separating propodeum and metapleuron, continuity of groove interrupted by spiracle ( Figs 2B , 4D ). Hind leg with femur about 4.3× as long as high and about 1.2× as long as tibia. Fore wing with vein cu-a opposite to Rs & M; vein 2 rs-m about 0.6× 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 1.5× as long as Cu 1 b. Hind wing with vein cu-a about 0.43× as long as abscissa of Cu 1 between M and cu-a; vein cu-a reclivous; abscissa of Cu 1 reclivous and straight; distal abscissa of Cu 1 well pigmented.

Metasoma ( Figs 4 E–F). Tergite I about 1.3× as long as posteriorly broad, shiny, with fine and relatively dense setiferous punctures more extended laterally; spiracle near its basal 0.3; lateromedian longitudinal carinae weak, reaching about 0.4 of length of tergite; lateral longitudinal carinae weak, reaching spiracle. Sternite I extending back about 0.4 of length of tergite ( Fig. 4F ). Tergite II about 0.9× as long as posteriorly broad, central region shiny, with fine and relatively dense setiferous punctures ( Fig. 4E ); lateral part weakly rugulose, rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor slender, strongly up-curved at distal 0.26, about 2.1× as long as hind tibia ( Fig. 4F ). Ovipositor sheath about 1.75× as long as hind tibia, length of setae on average about 1.5× the sheath basal width. Ventral margin of ovipositor sheath basally with numerous small denticles.

Colouration. Head mostly black with mandibles basally, most of clypeus, facial, frontal and vertical orbits, and a triangular mark on subventral part of genal orbit, white ( Figs 4 A–C); antenna dark brown. Mesosoma mainly red, with dorsal anterior mark and dorsal margin of pronotum, tegula, two longitudinal fine stripes widely interrupted by notauli and two spots on posterior corners of mesoscutum, two basal spots an posterior part of scutellum, posterior part of postscutellum, ventral part of subalar prominence, a spot on upper part of epicnemial carina, mesepimeron, and lateral longitudinal stripes on propodeum, white ( Figs 4 A–B, 4D); pronotum, except white parts, margins of mesoscutum, anterior part of notauli, scutellum except white marks, basal part of postscutellum, axillae, propleuron, dorsal part of subalar prominence, ventral part of prepectum, epicnemial carina, dorsal part of speculum narrowly, and propodeum except white stripes, black. Metasoma mostly black ( Figs 4 E–F), with narrow transverse white bands on posterior margins of tergites I to VII and whitish small marks on anterolateral corners of tergite I; ovipositor red, ovipositor sheath dark brown ( Fig. 4F ). Fore and mid legs predominantly whitish with coxae and trochanters dorsally and ventrally, dorsal and ventral stripes on femora and tibiae, and all tarsi, dark brown to black; hind leg predominantly dark brown to black with coxa dorsally and ventrally, trochanter apically and trochantellus, ventral and lateral stripes, and apical part of femur, tibia centrally, and basal ring on tarsi, white. Wings hyaline, pterostigma dark brown ( Fig. 1B ).
