(Figs 1C, 2C, 5)
Diagnosis. Clistopyga lapacensis may be distinguished from all other species of the C. diazi species group by the combination of the following characters: mesosoma extensively reddish (Figs 5 A–B); genal orbit widely black with a narrow white mark at ventral third (Fig. 5A); lateral part of pronotum reddish, dorsally and ventrally yellow-banded; propodeum dorsally black, laterally white; hind leg with coxa and femur black, widely white coloured; clypeal suture strongly curved (Fig. 5C); metapleuron about 2.46× as long as high; submetapleural carina well defined and almost complete, strongly arched inwards posteriorly (Fig. 2C); ovipositor and ovipositor sheath about 2.1× and 1.75× as long as hind tibia respectively (Fig. 5F); tergite I and II about 1.75× and 1.25× as long as wide respectively.
Description. Female: Body length about 11.7 mm (without ovipositor). Fore wing length about 9.2 mm.
Head (Figs 5 A–C). In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny with uniformly sparse setiferous punctures, in dorsal view almost straight, 0.24× as long as eye, in frontal view somewhat concave and moderately constricted below eyes. Frons and vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye about 1.1 its maximum diameter. Distance between hind ocelli about 0.7× maximum diameter of posterior ocellus. Occipital carina strong and complete (Fig. 5A). Face with dense setiferous punctures, distance between punctures about once or twice the diameter of punctures, more scattered laterally. Clypeal suture strongly curved (Fig 5C). Clypeus about 1.5× as broad as medially long, almost flat, apical margin weakly bilobed. Clypeal tentorial pits very small and shallow (Fig. 5C). Malar space about 0.8× as long as basal mandibular width, with a granulate wide stripe between eye and mandible. Antenna with 31 flagellomeres, first flagellomere 8.33× as long as wide.
Mesosoma (Figs 2C, 5 A–B). Pronotum mostly smooth and shiny with setiferous punctures on posterior dorsal corner. Epomia present as a very short and inconspicuous tubercle at anterior submarginal depression of pronotum (Fig. 5A). Mesoscutum shiny, with relatively very shallow setiferous punctures, much more dense on median lobe. Notauli deep, reaching about 0.5 the length of mesoscutum (Fig. 5B). Mesopleuron shiny, with moderately dense fine setiferous punctures, except in posterior part under speculum (Fig. 5A). Epicnemial carina weak, its dorsal end slightly curved back, reaching level of centre of pronotum. Metapleuron shiny, with very fine and scattered setiferous punctures, more dense at dorsal part, less dense on ventral part, 2.46× as long as high. Submetapleural carina extended on anterior 0.90 of metapleuron, strongly curved inwards posteriorly (Fig. 2C). Propodeum very finely and tightly transversally strigose (Fig. 5B), tending to be strongly and irregularly strigose at groove separating propodeum and metapleuron, with fine setiferous punctures more dense laterally, in dorsal view 1.57× as long as medially wide. Propodeal spiracle at groove separating propodeum and metapleuron, continuity of groove interrupted by spiracle (Fig. 2C, 5A). Hind leg with femur about 4.2× as long as high, 1.05× as long as tibia. Fore wing with vein cu-a opposite Rs & M; vein 2 rs-m about 0.8× 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 1.5× as long as Cu 1 b. Hind wing with vein cu-a 0.3× 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.
Metasoma (Figs 5 D–F). Tergite I about 1.75× as long as posteriorly broad, shiny, with dense setiferous punctures laterally and posteriorly, smooth on dorsal basal part, spiracle near its basal 0.4; lateromedian longitudinal carinae weak reaching 0.2 the length of tergite, lateral longitudinal carinae weakly insinuated anteriorly and posteriorly. Sternite I extending back 0.5 the length of tergite (Fig. 5F). Tergite II about 1.25× as long as posteriorly broad, with very dense fine punctures, distance between punctures about once its diameter (Fig. 5E); remaining tergites progressively more shallowly punctate. Ovipositor matt, evenly up-curved at 0.35 distal, 2.1× as long as hind tibia (Fig. 5F). Ovipositor sheath about 1.75× as long as hind tibia, length of setae on average 1.0–1.2× the sheath basal width. Ventral margin of ovipositor sheath basally with numerous very small denticles (Fig. 5D).
Colouration (Figs 1C, 5). Head mostly black with mandibles basally, clypeus, facial, frontal and vertical orbits, and a narrow mark on subventral part of genal orbit, white (Figs 5 A–C); antenna dark brown with lateral parts of scape and pedicel, whitish. Mesosoma mostly red; wide band on ventral margin and dorsal lateral margin of pronotum, tegula, subalar prominence, mesepimeron, lateral marks flanking the scuto-scutellar groove, posterior part of scutellum, postscutellum, and lateral longitudinal stripes on propodeum, white; pronotum with anterior dorsal part between white marks, posterior lateral margin and lower lateral corner, propleuron, ventral part of epicnemium, periphery of wings insertion, ventral part of metapleuron, axillae, basal part of postscutellum and propodeum except white stripes, black; central lobe of mesoscutum darkened posteriorly; scutellum basally dark red; ventral part of propleuron light brown (Figs 5A, 5B). Metasoma mostly black, with narrow transverse white bands on posterior margins of tergites I to VII (Fig. 5E), and whitish small marks on anterolateral corners of tergite I (Fig. 5F); ovipositor reddish brown; ovipositor sheaths dark brown (Fig. 5F). Fore and mid legs predominantly whitish with coxae and trochanters dorsally, dorsal and ventral stripes on femora, and tibiae dark brown, tarsi infuscate; hind leg predominantly dark brown to black with coxa dorsally and ventrally, trochanter apically and trochantellus, ventral and anterior lateral stripes, and apical part of femur, tibia centrally, and basal ring on tarsi, white. Wings hyaline, pterostigma dark brown (Fig. 1C).
