(Figs 1A, 3A–E)
Diagnosis. Clistopyga isayae sp. nov. can be distinguished from all other species of the C. isayae species group by the combination of the following characters: mesosoma white and brown (Figs 1A, 3B); ocular orbits entirely bordered with white marks (Fig. 1A); clypeal suture strongly curved, clypeus 1.6 × as broad as medially long (Fig. 3A); occipital carina present only ventrally as a vestige; hind wing with vein cu-a about 0.3 × as long as abscissa of Cu 1 between M and cu-a, abscissa of Cu 1 slightly curved (Fig. 3E).
Description. Female: Body length 10.2 mm. Fore wing length 7.1–7.3 mm.
Head (Figs 3A–B). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view 0.3 × as long as eye (Fig. 3B), in frontal view slightly convex and moderately constricted below eyes. Frons smooth and shiny. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 1.0 × its maximum diameter (Fig. 3B). Distance between hind ocelli 0.8 × maximum diameter of posterior ocellus. Occipital carina present only ventrally as a short vestige. Face with fine and dense setiferous punctures, distance between punctures more than twice the diameter of punctures. Clypeal suture stronly curved (Fig. 3A). Clypeus 1.6 × as broad as medially long, distinctly convex in dorsal half, flat in ventral half, with apical margin bilobate. Malar space 0.75 × as long as basal mandibular width, with a granulate stripe between eye and mandible (Fig. 3A). Antenna with 26 flagellomeres, first flagellomere 8.0 × as long as wide.
Mesosoma (Figs 1A – 3B). Pronotum shiny, mostly smooth, with fine and sparse setiferous punctures in upper posterior part. Mesoscutum entirely smooth and shiny, with fine and sparse setiferous punctures. Notauli deep, reaching about 0.46 of length of mesoscutum (Fig. 3B). Mesopleuron shiny, with moderately sparse setiferous punctures, except in posterior part under speculum. Subalar prominence sparsely punctate, with about 15–17 setiferous punctures. Epicnemial carina weak, its dorsal end straight, ending at level of centre of pronotum. Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior end, 2.55 × as long as deep. Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally, in dorsal view 1.27 × as long as medially wide. Propodeal spiracle contiguous with groove separating propodeum and metapleuron, groove not interrupted by spiracle (Fig. 1A). Hind leg with femur 3.80 × as long as deep, 0.90 × as long as tibia.
Wings (Figs 3D–E). Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m about 0.4 × 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 1.3 × as long as Cu 1 b (Fig. 3D). Hind wing with vein cu-a about 0.3 × as long as abscissa of Cu 1 between M and cu-a (Fig. 3E). Vein cu-a reclivous, abscissa of Cu 1 vertical and slightly curved. Vein Cu 1 well pigmented.
Metasoma (Fig. 1A, 3C). Tergite I 1.55 × as long as posteriorly broad (Fig. 3C), smooth and shiny, with fine and relatively dense setiferous punctures laterally; spiracle near its basal 0.35; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carinae weak, reaching about 0.3 of length of tergite. Sternite I extending back about 0.5 of length of tergite. Tergite II 1.25 × as long as posteriorly broad (Fig. 3C), central region shiny, with very fine and moderately sparse setiferous punctures; rest of tergites shiny, progressively more densely and strongly punctate. Ovipositor slender, shiny, very weakly upcurved at distal 0.3, 3.1 × as long as hind tibia (Fig. 1A). Ovipositor sheath about 2.3 × as long as hind tibia, length of setae on average about 1.8 × the sheath basal width.
Colouration. Head white with occipital region, vertex, frons centrally, and apex of mandibles black; antenna brown, ventrally pallid at base, with pedicel and scape ventrally white; face with a rhombic central brown mark; malar sulcus and clypeal suture brown (Figs 1A, 3A, B). Mesosoma white with lateral central part of pronotum, most of mesoscutum (except for lateral longitudinal stripes on median lobe and two pairs of longitudinal stripes on lateral lobes), longitudinal mark under subalar prominence and speculum, area around episternal scrobe, blotches on lower front corner and lower hind corner of mesopleuron, margin of metapleuron, groove separating propodeum and metapleuron, and a broad stripe mediodorsally along propodeum brown (Figs 1A, 3B). Metasoma with tergite I mainly white, mediodorsally and ventrally reddish brown, and with lateral posterior margins marked with black; tergites from II to the last more or less entirely reddish brown, tergites II–IV with white preapical posterolateral marks, and black marked posterolaterally (Figs 1A, 3C); ovipositor sheath brown. Legs white; mid and hind coxae, trochanteral segments, and femora and tibiae of all legs dorsally and ventrally striped with brown; tarsi infuscate. Wings hyaline, pterostigma brown.
Male: unknown.
