Diagnosis. Body medium-sized to large; antenna densely setose, longer than fore wing, and with 50–100 antennomeres, rarely less; terminal flagellomere usually acute apically, median flagellomeres usually wider than long, scapus often robust and ovoid, scapus in lateral view basally rounded and at inner side usually with narrow apical ledge, rarely as a double apical margin (I. ameeni: Fig. 30h), ventrally longer than dorsally and concave apically; eye glabrous, not or rather weakly emarginated; face often largely smooth, sometimes punctate, or with lateral sculpture; clypeus moderately wide and usually with dorsal carina; malar suture often developed, but sometimes weak; labiomaxillary complex normal, not elongate; frons not or weakly concave behind antennal sockets, with distinct median groove; notauli usually only impressed anteriorly; precoxal suture absent; mesopleural suture smooth; propodeum smooth, rarely with short carina posteriorly; angle between veins 1-SR and C+SC+R of fore wing more than 50°; vein 1-SR+M of fore wing more or less straight, rarely weakly curved; fore wing vein 3-SR relatively long, often more than twice longer than vein r-m; fore wing vein r-m usually weakly curved and with 2 bullae; fore wing vein cu-a interstitial or finely postfurcal; fore wing vein 3-CU1 not or only weakly expanded posteriorly; hind wing vein 1r-m often shorter than vein SC+R1 (rarely longer, only in some Indo-Australian species); hind wing basally often with some setae around vein cu-a; claws simple; legs more or less densely setose; metasomal tergites largely smooth or first–third metasomal tergite largely sculptured; first metasomal tergite with convex median area, medio-longitudinal carina present or absent; second tergite without medio-basal area, antero-lateral areas indistinct to developed; second suture usually crenulate, rarely smooth; third metasomal tergite often with antero-lateral areas; subposterior transverse groove of third–fifth tergites usually absent, but sometimes present; sixth and seventh tergites largely smooth; ovipositor usually robust and its upper valve often strongly enlarged and without nodus and at least twice wider than lower valve in lateral view, but sometimes slender, subapically upper valve without nodus, and its lower valve without distinct ventral teeth, rarely minute teeth present.
Biology. Most species are idiobiont ectoparasitoids of concealed larvae of Coleoptera (Buprestidae and Cerambycidae) and of Lepidoptera (Cossidae, Psychidae and Pyralidae) (Whitaker et al. 2007; Yu et al. 2016).
Distribution. Cosmopolitan. The distribution of Chinese species see Fig. 48.
