(Figs 1A, 2A, 3A, 4A, 6 A–F, 9B, 10B, 10D, 10F, 12A–E)

Clistopyga eldae Gauld, 1991: 296 . Holotype: ♀, Costa Rica (INBio, currently MNCR).

Diagnosis. Clistopyga eldae 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 absent, cu-a +first abscissa of Cu 1 not angled, straight, slightly reclivous (Fig. 3A); tergite I coarsely rugulose punctate laterally; tergite II coarsely and closely punctate centrally (Fig. 2A). Additionally, the male has lower part of gena not deeply concave and hypostomal carina not specially developed (Fig. 10B).

Description. Female: Body length 6–6.5 mm (without ovipositor). Fore wing length 4–5 mm.

Head (Figs 6 A–C). In dorsal view, moderately narrowed behind eyes. Gena smooth and shiny with very sparse setiferous punctures, in dorsal view slightly rounded, almost straight, 0.24–0.32× as long as eye (Fig. 6C), in frontal view straight and strongly constricted below eyes (Fig. 6B). Frons smooth and shiny. Vertex smooth and shiny, with very isolated setiferous punctures. Posterior ocellus separated from eye 0.8–1.0× its maximum diameter. Distance between hind ocelli 0.58–0.70× maximum diameter of posterior ocellus. Occipital carina weakly insinuated dorsally (Fig. 6A) or absent. Face with fine and scattered setiferous punctures, distance between punctures much more than three times the diameter of punctures. Clypeal suture slightly curved (Fig. 6B). Clypeus 1.60–2.20× as broad as medially long, slightly convex, dorsally, conspicuously concave ventrally, apical margin something bilobed. Malar space 0.1–0.33× as long as basal mandibular width, with a very short granulate area between eye and mandible. Antenna with 27 flagellomeres, first flagellomere 7.17–8.3× as long as wide.

Mesosoma (Figs 3A, 4A, 6C, D). Pronotum smooth and shiny. Epomia as a weak short tubercle. Mesoscutum smooth and shiny, with very fine and sparse setiferous punctures (Fig. 6C). Notauli weak, reaching about 0.4 of length of mesoscutum. Mesopleuron shiny, with very sparse setiferous punctures, except in posterior part under speculum. Epicnemial carina strong, its dorsal end straight, reaching a little below of centre of pronotum (Fig. 6D). Metapleuron shiny, glabrous, except for some sparse setiferous punctures at posterior dorsal part, 1.67–1.76× as long as deep. Submetapleural carina strong and complete, somewhat elevated at the anterior part (Fig. 4A). Propodeum smooth and shiny, with sparse and fine setiferous punctures laterally, in dorsal view 1.0–1.1× as long as medially wide. Propodeal spiracle joining groove separating propodeum and metapleuron. Hind leg with femur 3.7–3.96× as long as deep, 0.88–0.90× as long as tibia. Fore wing with vein cu-a opposite Rs & M. Vein 2 rs-m about 0.38–0.50× 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 1.1– 1.33× as long as Cu 1 b. Hind wing with vein cu-a+ abscissa of Cu 1 not interrupted by distal abscissa of Cu 1, slightly reclivous (Fig. 3A). Distal abscissa of Cu 1 absent.

Metasoma (Figs 2A, 6 E–F). Tergite I 1.8–2.1× as long as posteriorly broad, coarsely rugulose punctate, with moderately dense setiferous punctures laterally (Fig. 2A); spiracle near its basal 0.4; lateromedian longitudinal carinae strong, reaching about 0.5 of length of tergite; lateral longitudinal carinae strong, almost reaching posterior margin, something erased near the spiracle. Sternite I extending back about 0.8–0.9 of length of tergite (Fig. 6E). Tergite II 0.86–0.88× as long as posteriorly broad, coarsely punctate (Fig. 6F). Rest of tergites with shallow punctures. Ovipositor slender, matt, slightly bent up at distal 0.3 (Fig. 6E), 1.1–1.3× as long as hind tibia hind tibia. Ovipositor sheath about 0.98–1.1× as long as hind tibia, length of setae on average 1.83–2.2× the sheath basal width.

Colouration (Figs 1A, 6 A–F). Head black with clypeus, face, frontal and vertical orbits, mouth parts except apex of mandibles, malar space and ventral part of gena behind mandible base, white; antenna with scape and pedicel dark brown dorsally, widely white at ventral side, flagellomeres brown, basal flagellomeres whitish on the ventral side. Mesosoma predominantly reddish-orange; propleuron, anterior part of pronotum, tegula, ventral longitudinal band on mesopleuron between epicnemial carina and the insertion of the mid coxa, mesosternum, posterior part of metapleuron and lateral parts of propodeum, white; most part of metapleuron and dorsal longitudinal band on propodeum, dark brown; posterior rim of propodeum black. Metasoma mostly dark brown, anterolateral marks of tergites II, anterior part of tergite III extending back laterally and centrally, and lateral, anterior and posterior rims of tergites IV–VII, white. Legs predominantly white; mid leg with dorsal narrow stripe on femur and distal part of tibia brown; hind leg with anterior wide mark on coxa, anterior and posterior basal marks on trochanter, basal part and anterior longitudinal wide stripe on femur, tibia except mid part, and claws, brown. Wings hyaline, pterostigma dark brown. Ovipositor sheaths dark brown. Ovipositor reddish.

Male: Body length 5.2–7.0 mm. Fore wing length 3.6–4.8 mm.

Head (Figs 12A, B). Gena 0.35–0.36× as long as eye (Fig. 12A). Posterior ocellus separated from eye 0.85– 1.0× its maximum diameter. Distance between hind ocelli about 0.67× maximum diameter of posterior ocellus. Clypeus 1.65–1.68× as broad as medially long, weakly concave ventrally (Fig. 12B). Antenna with 26–27 flagellomeres, first flagellomere 6.7–7.2× as long as wide.

Mesosoma (Figs 12 C–D). Metapleuron 1.60–1.71× as long as deep (Fig. 11D). Hind leg with femur 3.8–4.0× as long as deep. Vein 2 rs-m about 0.50–0.53× as long as abscissa of M between 2 rs-m and 2 m-cu.

Metasoma (Figs 10F, 12E). Tergite I and tergite II, 1.84–2.04 and 1.34–1.35× as long as posteriorly broad, respectively (Fig. 10F).

Colouration (Fig 9B, 12 A–E). As in female but mesosternum orange (Fig. 12C), and whitish marks on tergites very weak (Fig 12E) or non-existent.

Other features as in female.
