Gasteruption Latreille, 1796: 113 –114 (description). See Crosskey (1962) and Carlson (1979) for taxonomic history and list of synonyms.

Type species. Ichneumon assectator Linnaeus, 1758 . Designated by Viereck (1914), according Carlson (1979).

Description. Body length between 8.0–20.0 mm (exclusive of ovipositor).

Head. Subtrapezoidal ( Fig. 2b View FIGURE 2. a – c ) or subrectangular in dorsal view; from wider than long to longer than wide; mandible in frontal view with apex acute ( Fig. 6 View FIGURE 6. a – g h); malar space short to medium, almost disconnected or fused to gena; clypeus without a ridge at anterior margin; clypeus and face without longitudinal striae ( Figs. 6c View FIGURE 6. a – g ); occipital margin simple, rarely crenulate.

Mesosoma. Pronotum with three well-defined lobes ( Figs. 13 View FIGURE 13 a-b); pronotal process present ( Figs. 13 View FIGURE 13 a-b), sometimes very short; propleuron simple anteriorly ( Fig. 8 View FIGURE 8 a); mesonotum rounded ( Figs. 13 View FIGURE 13 a-b) or slightly truncate in lateral view; mesoscutum uniformly sculptured, usually longer than wide, and forming two different planes separated by depressed notauli, parapsides distinct; mesepimeron entirely concave ( Figs. 13 View FIGURE 13 ab); fore and middle tibiae usually with a white stripe from base to apex; hind tibia usually white basally; metacoxa striate ( Fig. 14 View FIGURE 14 a), rugulose or smooth at posterior portion; median propodeal carina flattened ( Fig. 14 View FIGURE 14 d) or absent ( Fig. 14 View FIGURE 14 a); fore wing jugal lobe absent ( Fig. 7b View FIGURE 7. a – b ), rarely present; discal cell present (subtrapezoidal, subtriangular ( Fig. 7 View FIGURE 7. a – b c) or petiolate) or absent ( Fig. 7 View FIGURE 7. a – b d), vein r–m absent; vein 2–M tubular in first 1/3 and nebulous (rarely spectral) in remaining portion ( Fig. 7b View FIGURE 7. a – b ); hind wing with 3–4 hamuli, usually not equidistant ( Fig. 2a View FIGURE 2. a – c ), rarely more than 4.

Metasoma. First metasomal tergum with edges almost touching each other, concealing most of first sternum ( Fig. 9 View FIGURE 9 a); female subgenital sternum with a slitlike Y-shaped or an open V-shaped notch (as Figs. 10 View FIGURE 10 ab); ovipositor from shorter than T2+T3 to longer than metasoma.

Distribution and Biology. Same as Gasteruptiinae.
