Figs 3 A, 4A, C, 5A, C, 10C, 11C, E
Diagnosis
Clistopyga chaconi can be distinguished from all other species of the species group by the combination of the following characters: wings hyaline; propodeum and metapleuron black and white (Figs 3 A, 10C); clypeal suture slightly curved (Figs 4 C, 11C); antenna with 32 flagellomeres; occipital carina weakly raised, forming a flat flange dorsomedially (Figs 4 A, 11E). Female with metapleuron 1.5 times as long as deep; tergite II about 1.2 times as long as broad (Fig. 5 A) and malar space 0.9–1.1 times basal width of mandible. Male with face strongly and densely punctate (Fig. 11 C); first flagellomere about 4.8 times as long as wide; hind femur about 3.7 times as long as deep and malar space about 0.75 as long as basal mandibular width.

Paratype
COSTA RICA: 1 ♀, Guanacaste Prov., Guanacaste National Park, Cerro el Hacha, Casa oeste Tacotal, 400 m, Dec. 1986, coll. Gauld & Janzen (BMNH).
Remarks
Additional characters to the original description are as follow: female with vertex smooth and shiny, with very isolated setiferous punctures; occipital carina strong, weakly raised, forming a flat flange dorsomedially (Fig. 4 A); clypeal suture slightly curved (Fig. 4 C); hind leg with femur 3.57–3.70 times as long as deep; hind wing with vein cu-a + abscissa of Cu 1 between M and cu-a vertical; tergite I with lateral longitudinal carina absent; ovipositor sheath with length of setae on average 2.4–3.0 times the sheath basal width (Fig. 5 C). Male similar to female, but posterior ocellus separated from eye about 0.9 times its maximum diameter; distance between hind ocelli about 0.9 times maximum diameter of posterior ocellus; clypeus about 1.8 times as broad as medially long, quite strongly convex; malar space with deep and narrow sulcus between eye and mandible, about 0.8 times as long as basal mandibular width; lower part of gena, under eye, somewhat swollen (Fig. 11 C); first flagellomere about 4.8 times as long as wide; epicnemial carina ending far from anterior margin of mesopleuron at level of centre of pronotum; metapleuron about 1.6 times as long as deep; propodeum in dorsal view about 0.95 times as long as medially wide; vein 2 rs-m longer than half length of abscissa of M between 2 rs-m and 2 mcu; tergite I about 1.85 times as long as posteriorly broad; spiracle near its basal 0.35; lateromedian longitudinal carina reaching about 0.5 of length of tergite, lateral longitudinal carinae strong, reaching about 0.3 of length of tergite; sternite I extending back about 0.5 of length of tergite; tergite II about 1.45 times as long as posteriorly broad.
Distribution
Costa Rica. The male from Yucatan (Mexico), reported by Bordera et al. (2014) as C. chaconi, is a paratype of C. yabuquensis sp. nov.
