Head oval, occiput marginate, not expanding to form neck. Apex of masticatory of mandible with 3 teeth, followed by several indistinct denticles. Median of clypeus flat, with median ridge and lateral ridges, middle of anterior border concave. Frontal carinae short, lamellately projected. Frontal area large, triangular, impressed. Antennal sockets large. Antennae silk-formed, 1/3 length of scape extending occipital border; 4-segmented club distinctly swollen. Eyes roundly convex, situated in the midlength of the sides of head, pronotum flat above, anterior mesonotum slightly higher than pronotum, oblique backward; basal face of propodeum slightly convex, and slightly longer than declivity. Propodeal spines long and acute at tip, their length about as long as the distance between them, uppkward and divergently backward. Petiolar node subtriangular, blunt at tip, slightly longer than peduncle; postpetiole high, pear-liked, narrow anteriorly, the widest area about 1.5 X as wide as the width of petiolar node. Gaster oval.

Mandibles with fine longitudinal striations; head coarsely reticulate, interspaces feebly punctate. Pronotum smooth and shining, anterior area with dense fine punctures; mesonotum and propodeum coarsely reticulate and punctate; basal face of propodeum with regular transverse striations; declivity with fine transverse striations. Base of petiole and postpetiole finely punctate, dorsum of them smooth and shining. Base of first gastral segment finely punctate, remaining portion and other gastral segments smooth and shining.
