In full-face view head longer than broad, posterior margin strongly concave. Mandibles linear, gradually broadened apically; inner margin with 11 denticles; apical five denticles equally sized, remaining denticles gradually decreasing in size towards base; apical portion with three distinct teeth. Clypeus with concave anterior margin, lateral portion forming two round lobes above the base of mandibles. Antennae 12-segmented; scapes long, surpassing to posterior corners of head by 1/10 of its length. Eyes moderately large; maximum diameter of eye equal to the basal width of mandibles.
In lateral view mesosoma slender; pronotum moderately convex. Promesonotal suture narrowly notched. Mesonotum with a transverse ridge anteriorly. Metanotal groove deeply depressed. Dorsum of propodeum almost straight, sloping posteriorly; posterodorsal coner of propodeum narrowly rounded. Petiole cone-shaped, with a pointed dorsal apex, anterior margin slightly longer than posterior margin; subpetiolar process developed, directed posteroventrally as a distinct hook.
Frons longitudinally to obliquely striate posteriorly; remainder of head smooth and shining. Mesosoma smooth and shining, upper portion of lateral pronotum longitudinally striate, metathorax and propodeum obliquely rugose. Petiolar node smooth and shining, basal area faintly striate. Gaster smooth and shining.
Body dorsum with abundant erect to suberect hairs and sparse decumbent pubescence; scapes with sparse suberect hairs and abundant subdecumbent pubescence, tibiae with abundant suberect hairs and sparse decumbent pubescence. Body reddish brown; head, mandibles and antennae blackish brown; legs yellowish brown.
