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.

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.
