Diagnosis.

Body large; terminal antennomere often strongly acute apically; median antennomeres usually weakly wider than long; in lateral view scapus without double margin or with narrow ledge at inner side apically and slightly concave apico-laterally, ventrally longer than dorsally; eye glabrous, not or weakly emarginate; face strongly sculptured, depressed below and between the antennal sockets; clypeus moderately narrow, rugose and often without dorsal carina; malar suture moderately developed, often rugose; labio-maxillary complex normal, not elongate; frons strongly depressed, with a weak median groove; middle lobe of mesoscutum protruding strongly in front of lateral lobes; notauli developed and complete; scutellar sulcus narrow and crenulate; scutellum sometimes with an emargination medio-anteriorly; metanotum convex medially, and sometimes with a short and somewhat protruding median carina; propodeum often smooth, without medio-longitudinal carina or groove; angle between veins 1-SR and C+SC+R of fore wing more than 75°; vein 1-SR+M of fore wing evenly and strongly arched, forms with bases of vein 1-SR+M and 1-M a widened inverted “Y”; vein m-cu of fore wing widened; second submarginal cell of fore wing relatively long and parallel-sided; vein cu-a of fore wing interstitial or slightly postfurcal; hind wing vein 1r-m often distinctly shorter than SC+R1; claws simple; T I with parallel angulate sides of medial area, and comparatively flat, usually with lateral and medio-longitudinal carinae; T II usually with a triangular medio-basal triangular area connected to a medio-longitudinal carina apically, but absent near posterior margin of T II; second suture crenulate; hypopygium rather acute apically, usually beyond level of apex of metasoma; ovipositor normal, distinctly longer than body, subapically upper valve with nodus, and its lower valve with teeth ventrally.
