Head in lateral view very thick. Face and clypeus evenly, roundly convex. Face continued dorso-medially between antennal sockets as a strong, compressed, semicircular projection, its upper end close to median ocellus, its dorso-posterior part with median concavity. Gena long, straightly convergent or very slightly incurvate backwards. Lower tooth of mandible shorter than upper tooth. Occipital carina strong and complete. Scutellum weakly convex, without lateral carina except basolateral corner. Fore wing 1cu-a distal of 1/M by 0.2 - 0.7 its length. Areolet usually present. Hind wing 1-cu longer than cu-a. Pterostigma broad. Epicnemial carina strong, upper end reaching anterior end of subalar prominence. Metapleuron smooth, polished. Front and mid femora rather thick. Mid tibia with two spurs. Fifth tarsomere of female with or without a ventral, subapical projection. Tarsal claw simple. Propodeal spiracle subcircular to elliptic. Metasoma short, robust. First tergite usually broad basally, its spiracle approximately at basal 0.25, its sternite reaching approximately to 0.2 length of tergum. Subgenital plate of female with or without apical-median notch. Ovipositor not projecting beyond tip of metasoma.
