See Figures in Victorino et al. (2023).

Diagnosis. Clistopyga tundisii can be distinguished from other species in the C. chaconi species group by the combination of the following characters: wings hyaline; gena in dorsal view 0.7× as long as eye; clypeus 1.2× as broad as medially long; malar space 0.5× as long as basal mandibular width; mesosoma yellow with white marks at post margin of mesopleuron and subalar prominence; scutellum whitish; tegula yellow; propodeum and metapleuron light yellow; occipital carina strongly raised, forming a dorsomedial flange, conspicuously upcurved posteriorly; epicnemial carina strong ending at the level of center of posterior margin of pronotum; fore wing with vein 2 rs-m about 0.8× length of abscissa of M between 2 rs-m and 2 m-cu; abscissa of Cu 1 between 1 m-cu and Cu 1a about 3.0× as long as Cu 1b; ovipositor stout, shiny, strongly upcurved over apical 0.3, about 1.5× as long as hind tibia; metasoma black with posterior transversal white stripes on tergites I–VII; sternite I extending back about 0.6 of length of tergite.

Remarks. Material from Brazil was wrongly identified by Victorino et al. (2023) in the genus Zonopimpla . After analyzing other specimens, we hereby present a redescription of the species.

Redescription. Female. Body length 8.0 mm. Fore wing length 6.0 mm.

Head. In dorsal view, strongly narrowed behind eyes. Gena smooth and shiny, with very sparse, moderately long setae ventrally, in dorsal view 0.7× as long as eye. Frons smooth and shiny, with a very weak medial longitudinal depression. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye about 0.8 times its maximum diameter. Distance between posterior ocelli about 1.2× maximum diameter of posterior ocellus. Occipital carina strongly raised, forming a dorsomedial flange, conspicuously upcurved posteriorly. Face with fine and dense setiferous punctures, distance between punctures about diameter of punctures. Clypeal suture slightly curved. Clypeus 1.2× as broad as medially long, weakly convex in dorsal half, flat in ventral half, with apical margin truncate. Malar space 0.5× as long as basal mandibular width, with short sulcus between eye and mandible, evanescent towards mandibular base, forming a wide triangular granulate area. Antenna with 34 flagellomeres, first flagellomere about 7.0× as long as wide.

Mesosoma . Pronotum shiny, mostly smooth, with fine and sparse setiferous punctures in upper posterior part. Mesoscutum smooth and shiny, with very sparse setiferous punctures on median and lateral lobes. Notauli moderately deep, reaching about 0.5× length of mesoscutum. Mesopleuron shiny, mostly smooth, with moderately sparse and fine setiferous punctures except in dorsal posterior part. Epicnemial carina strong, its dorsal end not curved backward, ending far from the anterior margin of mesopleuron at the level of center of pronotum. Metapleuron smooth and shiny, with fine and sparse setiferous punctures, almost glabrous, about 2.0× as long as deep. Submetapleural carina complete. Propodeum smooth and shiny, with sparse and fine setiferous punctures except in dorsal posterior part; in dorsal view about 1.2× as long as medially wide. Propodeal spiracle contiguous, with groove separating propodeum and metapleuron, groove barely interrupted by spiracle. Hind femur 4.5× as long as deep, 1.1× as long as tibia. Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m about 0.8× length of abscissa of M between 2 rs-m and 2 m-cu. Abscissa of Cu 1 between 1 m-cu and Cu 1a about 3.0× as long as Cu 1b. Hind wing with vein cu-a 0.3× as long as abscissa of Cu 1 between M and cu-a. Vein cu-a + abscissa of Cu 1 between M and cu-a vertical. Vein Cu 1 weakly pigmented.

Metasoma. Tergite I 2.0× as long as posteriorly broad, smooth and shiny, with fine and relatively dense setiferous punctures laterally; spiracle near its basal 0.3; lateromedian longitudinal carinae strong, reaching about 0.2 of length of tergite; lateral longitudinal carinae absent. Sternite I extending back about 0.6 of length of tergite. Tergite II 1.2× as long as posteriorly broad, central and lateral regions shiny, with small, shallow and moderately sparse punctures; rest of tergites shiny, more densely punctate. Ovipositor stout, shiny, strongly upcurved over apical 0.3, about 1.5× as long as hind tibia. Ovipositor sheath about 1.3× as long as hind tibia, length of setae on average about 1.5× sheath basal width.

Colouration. Body primarily dark yellow, black and white. Head black, with light yellow marks on the face, base of the antenna, upper part of the clypeus, inner margin of the eye, palpi and lower part of the gena; mandible black with transversal light yellow stripe; antenna mostly black, pedicel and first flagellomere yellowish. Mesosoma dark yellow with white marks at the post margin of mesopleuron and subalar prominence; scutellum whitish; tegula yellow; propodeum and metapleuron light yellow. Fore leg dark yellow. Mid leg dark yellow with the ventral part of coxa apically black, tarsi yellow brownish. Hind leg with coxa white dorsally and black ventrally, trochanter predominantly black with a white spot apically, femur black with basal and subapical spots white, tibia white and black at the base and apex, tarsi white at base with black apex. Wings hyaline, pterostigma blackish. Metasoma black with anterior corners of tergites I–III and posterior band of tergites I–VII white, posterior corners of tergites I–IV with black spots. Ovipositor reddish brown, sheath blackish.

Comments. Clistopyga tundisii (Penteado-Dias & Victorino) differs from C. misionensis Bordera & Sääksjärvi by the following characters: mesosoma dark yellow with white marks at post margin of mesopleuron and subalar prominence, scutellum whitish, tegula yellow (mesopleuron, scutellum and tegula in C. misionensis entirely orange); wings hyaline (with a slightly yellow tint in C. misionensis ); clypeus 1.2× as broad as medially long (1.52–1.74× in C. misionensis ); gena in dorsal view 0.7× as long as eye (0.31–0.38× in C. misionensis ); malar space 0.5× as long as basal mandibular width (0.75–0.85× in C. misionensis ); propodeal spiracle contiguous, with groove separating propodeum and metapleuron, groove barely interrupted by spiracle (situated above groove separating propodeum and metapleuron in C. misionensis ); abscissa of Cu 1 between 1 m-cu and Cu 1a about 3.0× (1.53–2.0× in C. misionensis ) as long as Cu 1b; lateral longitudinal carinae absent (present and strong in C. misionensis ).
