Worker
Holotype worker. TL 2.45, HL 0.58, HW 0.58, CI 100, SL 0.48, SI 83, PW 0.42, ML 0.64. Paratype worker. TL 2.65, HL 0.61, HW 0.61, CI 100, SL 0.53, SI 87, PW 0.43, ML 0.62 (1 measured).

Head subrectangular, as long as broad in full-face view; median portion of occipital margin concave; occipital corners rounded, not projected posteriorly. Masticatory margin of mandible bent at midlength (third small tooth or sixth tooth); apical tooth strong, third tooth robust, followed by 5 small teeth and a basal blunt tooth; small teeth unclear. Dorsal surface of clypeus concave; median portion of anterior margin projected with a median process that are very small; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with paired small denticles distinctly. Frontal carinae virtually absent, indistinguishable from rugae on dorsum of head. Eyes large and convex with maximum diameter 0.08 mm, with 5 ommatidia; malar space twice as long as diameter of eye in profile; distance between occipital margin and posterior margin of eye three times as long as diameter of eye. Antennal scape short, just reaching posterolateral corner of head; antennal flange weakly developed.

Dorsal outline of mesosoma slightly convex in profile. Pronotum without denticles; anterior portion marginate; anterior ventrolateral portion angulate. Furrow between pronotum and mesoepisternal projection broad. Eumetanotal spine present but small; length shorter than broad at base. Propodeal spine elongate, directing backward and weakly curved upward, extending over vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle large, situated near posterior margin of propodeum, apart from the margin by its diameter. Petiole short, as long as high in profile, and longer than broad in dorsal view; small but distinct dorsal crest located at midlength in profile; subpetiolar process small with acute anterior apex clearly. Postpetiole broader than petiole and expanded anteriorly in dorsal view; dorsal outline flattened or slightly convex in profile; ventral outline not projected.

Anterior margin of gaster not concave in dorsal view; first gastral sternum simple without median longitudinal ridge.

Head punctured with thin rugae longitudinally; ventrolateral portion shining, but punctured. Clypeus smooth and shining. Mesosoma punctured with thin rugae longitudinally. Forecoxa smooth and shining. Petiole and postpetiole with a few distinct rugae. First gastral segment smooth and shining. Head with dense and short pilosity on dorsum. Mesosoma with dense and short pilosity on dorsum, hairs of pronotum shorter than apical third segment of antenna. Petiole without hairs on ventral surface. Postpetiole with 2 hairs on ventral surface. Body black to dark reddish brown, mandibles, antennae and legs brown to yellowish brown.
