Worker
Holotype. TL 3.4, HL 0.88, HW 0.83, CI 94, SL 1. 12, SI 134, PW 0.53, AL 1.18, EL 0.18. Paratypes (n=5). TL 3.1–3.6, HL 0.73–0.88, HW 0.70–0.83, CI 92–96, SL 0.93–1.12, SI 133–136, AL 1.10–1.18, EL 0.16–0.18.

Head longer than broad, or as broad as long. Clypeus convex, with a strong longitudinal carina in the middle, anterior margin shallowly and broadly concave. Mandibles with 5 teeth, the 3rd reduced. Eyes ovate, feebly convex, moderately large, placed behind the mid length of head. Antennae long, scapes extending about 1/3 of their length beyond posterior margin of head. Frontal carina short, reaching to anterior margin of eyes. Mesosoma stout, strongly medially constricted; in lateral view pronotum and mesonotum together form a convexity; propodeum low, broadly rounded with declivous face obliquely truncate, the latter longitudinally impressed in the middle; petiolar node inclined forward, posterodorsal corner rounded, dorsal face longitudinally concave in the middle when view from behind. Gaster slightly longer than head.

Smooth and shining; mandibles weakly striate, frontal area of head without reticulations, several short longitudinal striations present on posterior portion of mesonotum where it joins propodeum. Setae soft, weak, and short, the longest satae are on clypeus, reaching up to 0.175 mm. Colored yellowish brown, gaster brown.
