Genus Euurobracon Ashmead, 1900

Euurobracon Ashmead, 1900:140 . Type species: Bracon penetrator Smith, 1877 .

Diagnosis. [after Li et al., 2016]; Antennae 50–80 segmented most of the flagellomeres as long as wide, apical flagellomere robust, sub conical, sometimes distinctly acuminate, occasionally fused or partly fused with the penultimate flagellomere ( Fig. 2F). Scapus longer dorsally than ventrally, not emarginated apico-laterally/apico-medially; mandibles large and twisted anteriorly, Clypeus without a ridge or carina, eyes glabrous, frons densely setose, with a mid-longitudinal sulcus posterior-laterally ( Figs 2D, 3A). Mesosoma largely smooth and shiny, pronotum with a distinctly crenulate transverse groove anteriorly and smooth laterally; mesoscutum smooth with notauli distinct anteriorly ( Fig. 2A). Scutellar sulcus completely smooth; propodeum more or less densely setose ( Fig. 3E). Fore wing vein 1- SR+M weakly evenly curved medially; vein cu-a strongly post-furcal and inclivous; 3-CU1 often strongly thickened posteriorly. Hind wing vein 1r-m longer than SC+R1 ( Figs 2C, 3D). Fore tibia somewhat swollen with one spur, more or less densely covered with regularly arranged small thick setae or spines antero-laterally; claws slender, simple, with the basal lobe reduced to a small basal protruding area, not especially protruding. Metasoma mostly smooth and shiny, first metasomal tergite with an anterior pit, dorso-lateral carinae absent; second metasomal tergite smooth, weakly curved medially, with a sub-lateral, longitudinal groove on either side, close to the margin ( Figs 2A–B, 3E). Third metasomal tergite with or without antero-lateral area defined posteriorly by antero-lateral posteriorly diverging smooth furrows; tergites 3–5 without any transverse sub-posterior grooves. Ovipositor length variable, 0.7–14.6× the fore wing length, with a distinct dorsal nodus and ventral terminal serrations.
