Workers have 11-segmented antennae. Body color dark reddish brown. Head in full-face view elliptical, distinctly longer than broad, lateral margins strongly convex, posterior margin almost straight, with posterolateral corner as blunt. Mesosoma in dorsal view rather robust, subrectangular, with almost parallel-sided lateral sides; in lateral view, dorsal outline slightly convex; propodeal declivity flat, encircled with indistinct rim. Petiole in dorsal view subquadrate, almost as long as broad, lateral margins nearly parallel-sided; in lateral view (excluding sternite) subrectangular, slightly shorter than high, dorsal outline convex, bilateral edge vertical; subpetiolar process in lateral view subrectangular with its ventral outline concave; ventrolateral surface of petiole with two distinct almost parallel carinae just above subpetiolar process. Postpetiole in lateral view rounded, shorter than high, with ventral outline concave; sternite anteroventrally produced as blunt angle directed downward and forward. Entire body finely reticulated with deep bottoms; antennal scape, outer face of mandible and legs punctate.
