Diagnosis. Mandibles elongate, distinctly cross each other. Clypeus longer than wide, usually emarginate apically ( Fig. 1 ). Cephalic fovea absent. Vertex usually sloping behind lateral ocelli. Mesosoma globular, as wide as high. Anterior face of pronotum smooth and shiny without medial pits or foveae. Pronotal carina usually present. Epicnemial carina absent. Pretegular carina absent ( Fig. 17 ). Notauli absent. Tegula longer than wide, emarginate adjoining parategula, not reaching end of parategula posteriorly. Metanotum not dentate. Axillary fossa wide. Propodeal dorsum below plane of metanotum, without dorsal shelf. Superior carinae absent. Submarginal carina not produced as pointed/rounded process. Propodeal valvula not free from submarginal carina posteriorly. Propodeal orifice wide dorsally. Metasoma petiolate, T1 punctate and abruptly widening near apex and bulged apically ( Fig. 75 ). S1 abruptly widening near apex, forming a posterior crescentic sclerite, lateral margins of T1 closely approaching each other ventrally, usually fused ( Fig. 68 ). T2 with translucent apical lamella ( Fig. 72 ). Mid tibia with one apical spur. SMC2 basally acute.
