Figs 1A–E

Diagnosis. Clistopyga hayesiana can be distinguished from other species in the C. chaconi species group by the combination of the following characters: body primarily orange, brown and white ( Fig. 1A ); propodeum and metapleuron entirely orange; hind coxa dorsally white cream, ventrally orange; wings hyaline with a slightly yellowish tint. Malar space 0.95× as long as basal mandibular width ( Fig. 1B ), with deep and narrow sulcus between eye and mandible, sulcus short, evanescent towards mandibular base, forming a wide triangular granulate area; occipital carina moderately raised, forming a dorsomedial flange, weakly upcurved posteriorly; epicnemial carina very weak, its dorsal end ending far from anterior margin of mesopleuron, considerably below level of center of pronotum; hind wing with vein cu-a about 0.9× abscissa of Cu 1 between M and cu-a; ovipositor slender, matt, sinuous, slightly upcurved over at apical 0.35, about 1.55× as long as hind tibia.

Remarks. The Brazilian specimens show some morphological variations or additional characters in relation to the original description of C. hayesiana Bordera & Sääksjärvi 2016 , as follows: head almost completely yellowish, but face with a weak to moderately present brown spot without a defined shape ( Fig. 1B ); basal and subapical part of the hind femur orange to dark brown. Body length 10.75–12.8 mm; fore wing length 7.9–8.2 mm ( Fig. 1A ). Antenna with about 36 flagellomeres, first flagellomere 5.0–5.3× as long as wide. Submetapleural carina complete and strong, very developed anteriorly ( Fig. 1D ). Hind wing with vein cu-a about 0.6× as long as abscissa of Cu 1 between M and cu-a ( Fig. 1C ); vein cu-a strongly reclivous; vein Cu 1 distinctly pigmented. We also add an additional character, sternite I with a weak to highly developed medial carina just below the glymma ( Fig. 1D ). Ovipositor strongly upcurved over at the apex 0.3–0.45.

Male: Unknown.
