Diagnosis.

Body medium-sized to large; terminal antennomere slightly acute apically; median antennomeres often longer than wide, rarely slightly wider than long; pedicellus petiolate; scapus highly modified, lower inner apical rim of inner side of scapus interrupted because of a second small, more apical area; eye glabrous, weakly emarginated; face with a more or less strongly produced medially, transverse ledge, sometimes with a medial horn-like and distally concave projection above this; clypeus moderately narrow and without dorsal carina; malar suture moderately developed; labio-maxillary complex normal, not elongate; frons broadly impressed, with some setae and a median groove; mesosoma largely smooth and shiny, often more or less strongly dorsoventrally compressed; notauli largely absent; scutellar sulcus narrow and crenulate; propodeum flattened; angle between veins 1-SR and C+SC+R of fore wing more than 75°; vein r-m of forewing usually with two bullae; apex of hind wing vein C+SC+R with one thickened bristle; base of hind wing with glabrous area distal to vein cu-a; claws simple; fore tarsus at least 1.6 × longer than fore femur (excluding trochantellus); fourth tarsal segment with numerous long bristles apico-ventrally, almost reaching apex of telotarsus; hind femur and tibia with relatively dense and long setae ventrally; lateral areas of T I wide and completely flattened; T II with deep oblique lateral grooves connected to wide sublateral grooves; antero-lateral grooves of T III short, and medial part of tergite 1.5 × wider than its lateral parts; T III-V with distinct oblique antero-lateral grooves; ovipositor with dorsal nodus and ventral serrations subapically.
