Worker
Holotype. TL 3.13, HL 0.78, HW 0.72, CI 93, SL 0.69, SI 96, PW 0.51, ML 0.86.

Head subrectangular, longer than 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 blunt basal tooth. Dorsal surface of clypeus not concave; median portion of anterior margin projected with four processes; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with small but distinct paired denticles, very close to each other. Frontal carinae virtually absent, indistinguishable from rugae on dorsum of head. Eyes medium-sized and convex with maximum diameter 0.11 mm, with 8 ommatidia; malar space twice as long as diameter of eye or shorter in profile; distance between occipital margin and posterior margin of eye three times as long as diameter of eye or longer. Antennal scape long, extending beyond posterolateral corner of head; antennal flange weakly developed.

Dorsal outline of mesosoma convex in profile. Pronotum without denticles on dorsolateral portion; anterior portion marginate; anterior ventrolateral portion angulate. Furrow between pronotum and mesoepisternal projection broad. Eumetanotal spine present but small. Propodeal spine triangular, as long as broad at base, not reaching vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle medium-sized, situated near posterior margin of propodeum, apart from margin by its diameter. Petiole short, slightly longer than high in profile, and slightly longer than broad in dorsal view; dorsal crest located at midlength in profile; subpetiolar process and median longitudinal ridge at ventral portion absent. Postpetiole slightly broader than petiole and expanded posteriorly in dorsal view; larger than petiole in profile; dorsal outline flattened; ventral outline slightly projected rectangularly.

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

Head punctured with thin rugae weakly; ventrolateral portion smooth and shining. Clypeus smooth and shining. Mesosoma with thick rugae diverging anteriorly on dorsal surface. Anterior portion of pronotum with a few transverse rugae in dorsal view. Forecoxa smooth and shining. Petiole and postpetiole with thick rugae. First gastral segment smooth and shining. Head with relatively dense and long pilosity on dorsum. Mesosoma with dense and long pilosity on dorsum, hairs of pronotum longer than propodeal spine. Petiole without hairs on ventral surface. Postpetiole with 4 hairs on ventral surface. Body black, mandibles, antennae and legs yellowish brown to brown, forecoxae dark reddish brown.
