The Clistopyga henryi species-group

Diagnosis. Females can be distinguished by clypeus distinctly convex in dorsal half, flat in ventral half, with apical margin straight to slightly concave; gena, in anterior view, slightly concave and constricted below the eyes ( Figs 3A , 4A , 5A , 6A ); occipital carina complete, inconspicuous to slightly raised in the lower lateral region of head, not raised in a flange-like protuberance; occiput in dorsal view slightly concave; malar space 0.5–0.8× as long as basal mandibular width; antenna with 24–27 flagellomeres, first flagellomere 8.0–9.7× as long as wide; epomia strong, vertical; posterior part of median lobe of mesoscutum prominent; metapleuron 1.6–1.9× as long as deep; propodeum without lateromedian longitudinal carina, 0.9–1.2× as long as medially wide in dorsal view; groove separating propodeum and metapleuron not or partially interrupted by spiracle; submetapleural carina only present at anterior 0.3–0.5 ( Figs 7B, C, D ) or complete ( Fig. 7A ); fore leg with tibia swollen in their basal half ( Figs 9C, D ); hind leg with femur 4.5–5.4× as long as deep and 0.8–1.0× as long as tibia; sternite I of metasoma extending back 0.3–0.5× length of tergite; ovipositor relatively, long, 2.6–3.2× as long as hind tibia, shaft straight ( Figs 2 , 5D , 6D ) or evenly down-curved at distal 0.4 ( Figs 1 , 3D , 4D ), not denticulate in basal 0.35, surface virtually smooth and shiny, upper valve with apex evenly tapered; ovipositor sheath 2.3–2.5 × as long as hind tibia, without denticles at basal ventral margin.

The only known male within this species group is the male of C. henryi ( Figs 10 , 11 ) which can be distinguished from all other New World males by combination of the following characters: ventral part of gena with conspicuous longitudinal concavity ( Fig. 11A ); submetapleural carina entirely absent or as a vestige on anterior third of metapleuron; mesoscutum, mesopleuron and metapleuron more or less entirely reddish-orange; propodeum almost entirely black or dark brown ( Fig. 11B ), sometimes with two small posterolateral white marks; metasoma almost entirely black with small posterolateral white marks before posterior margin ( Figs 11C, E ) ( Gauld, 1991; Bordera et al. 2014).
