Ischnobracon Baltazar, 1963: 588; Quicke 1987: 117; Butcher and Quicke 2010: 2188. Type species: Ischnobracon bakeri Baltazar, 1963.

Diagnosis.

Body medium-sized to large; antenna longer than fore wing; terminal antennomere pointed, but not acute apically, median antennomeres distinctly wider than long; in lateral view scapus without double margin at inner side apically and strongly concave apico-laterally, ventrally ca. as long as or rarely slightly shorter than dorsally; eye large and glabrous, weakly emarginate; face weakly and sparsely punctate; clypeus moderately narrow and without dorsal carina, above clypeus with shallow triangular depression; malar suture moderately shallow; labio-maxillary complex normal, not or slightly elongate; frons weakly depressed, with some setae and a median groove; mesosoma smooth and shiny; notauli only impressed anteriorly; scutellar sulcus completely smooth; median area of metanotum relatively small; propodeum smooth and flattened; angle between veins 1-SR and C+SC+R of fore wing less than 40°; vein 1-SR+M of forewing usually straight, rarely slightly curved after arising from 1-M; forewing vein 3-CU1 usually more or less expanded posteriorly; second submarginal cell of fore wing distinctly expanded distally; forewing vein cu-a postfurcal or more or less interstitial; hind wing vein 2-SC+R usually interstitial or distinctly transverse (but longitudinal in I. indiscretus ); hind wing with five to eight basal bristles; claws simple; fourth tarsal segment more or less protruding at inner side apically; metasoma in dorsal view relatively slender; T II with large rhombic medio-basal area and laterally depressed, resulting in a narrow medial part; T III often with large and raised antero-lateral areas; T III-V without deep oblique antero-lateral grooves; ovipositor with weak dorsal nodus and small ventral serrations subapically.
