Holotype. TL 3.2, HL 0.78, HW 0. 55, CI 70, SL 0.44, SI 80, PW 0.37, AL 0.83. Head longer than broad, dorsum strongly longitudinally convex, very thick from dorsal margin to ventral margin of the head capsule in lateral view lateral sides weakly convex, occipital border nearly straight. Masticatory borders of mandibles with 3 distinct apical teeth, followed by 4 indistinct denticles. Anterior clypeal border straight. Antennal scapes not reached to occipital corners. Eyes large, situated at the midlength of the sides of the head. In lateral view, promesonotal dorsum relatively straight, promesonotal suture indistinct, visible on lateral sides; metanotal groove notched. Propodeal spines triangular in lateral view, brood at base, acute at tip. Propodeal dorsum feebly convex. Petiole without anterior peduncle, petiolar node roughly triangular, anterior face straight, posterior face convex, dorsum bluntly rounded. Subpetiolar process broad, anterior angle bluntly rounded. Dorsum of postpetiole rounded, lower than petiole, 1.5 times broad as petiole in, dorsal view. Gaster oval.
Mandibles finely longitudinally striate, interface smooth and shining. Clypeus coarsely longitudinally rugose and punctate. Dorsum of head coarsely longitudinally rugose, reticulate at occipital corners, interface coarsely punctate. Dorsum of alitrunk coarsely reticulate and punctate. Sides of alitrunk irregularly longitudinally rugose and coarsely punctate. Petiole and postpetiole densely punctate. Gaster smooth and shining. Color dark reddish brown; dorsum of head, alitrunk, petiole, postpetiole, and whole gaster darker, mandibles, antennae, and legs lighter.
Paratype. TL 3.2-3.4, HL 0.78-0.80, HW 0.55-0.58, CI 70-72, SL 0.44-0.48, SI 80-82, PW 0.37-0.40, AL 0.83-0.86 (3 individuals measured). As holotype.
