The Clistopyga eldae species-group

Diagnosis. Female of this species group may easily be distinguished from other Clistopyga species groups by malar space very short 0.1–0.45× as long as basal mandibular width, sternite I very long, extending back more than 0.75× length of tergite, and ovipositor relatively short, 1.0–1.28× as long as hind tibia ( Figs 1 A–D), ovipositor sheath 0.78–1.11× as long as hind tibia, without denticles at basal ventral margin. Additional characters are as follow: clypeus slightly convex in dorsal half, flat or concave in ventral half, with apical margin straight to weakly bilobed; gena in anterior view straight or almost straight and moderately to strongly constricted below eyes ( Figs 5B , 6B , 7B , 8B ); occipital carina from complete to inconspicuous; occiput in dorsal view slightly concave; antenna with 27–31 flagellomeres, first flagellomere 7.17–10.0× as long as wide; epomia absent or as a weak short tubercle; metapleuron 1.67–2.1× as long as deep; propodeum 1.0–1.2× as long as medially wide in dorsal view; groove separating propodeum and metapleuron interrupted by spiracle; submetapleural carina only present at anterior part of metapleuron ( Fig. 4D ) or complete ( Figs 4 A–C); hind leg with femur 3.58–4.74× as long as deep and 0.85–0.91× as long as tibia; ovipositor weakly bent up or up-curved at apical 0.3–0.5, not denticulate in basal 0.35, surface matt. Males are characterized by sternite I extending back more than 0.75 of length of tergite I ( Figs 11D , 12D ).
