Postclypeus more chitinised, large and pilose, convex with median line. Antennae with 19–22 segments. Left mandible with second marginal longer than first and subequal to third. Right with first marginal sharp and longer than second with long posterior margin. Pronotum less wide than head, anterior margin generally substraight or feebly incurved, posterior margin weakly outcurved. Wings strongly reticulate, moderately hairy. Median of both wings coming out of cubitus or not separated from cubitus. Tibial spur formula 3:2:2. Soldier: Head oval, distinctly narrowed in front, sparsely pilose. Eyes present indistinctly. Fontanelle small with clear groove running in front up to clypeus, fontanelle gland distinct. Antennae with 16–19 segments. Labrum dome-shaped with moderate hairs.
