Worker
Holotype. TL 2.31, HL 0.56, HW 0.51, CI 91, SL 0.45, SI 88, PW 0.35, ML 0.59.

Head subrectangular, longer than broad in full-face view; median portion of occipital margin flattened; 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 4 small teeth and a blunt basal tooth. Dorsal surface of clypeus not concave; median portion of anterior margin feebly projected without a median process; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with paired small denticles, close to each other. Frontal carinae present but very short, running back to the level of the posterior margin of the eyes. Eyes extremely small circularly and moderately convex with maximum diameter 0.05 mm, with 6 ommatidia; malar space twice as long as diameter of eye or longer in profile; distance between occipital margin and posterior margin of eye four times as long as diameter of eye or longer. Antennal scape short, just reaching 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 much reduced and unclear. Propodeal spine only angulately projected, not spine-like in profile. Propodeal lobe low. Propodeal spiracle very large, situated near posterior margin of propodeum, distance between posterior margin of spiracle and posterior margin of propodeum shorter than diameter of spiracle. Petiole long, longer than high in profile, and longer than broad in dorsal view; dorsal crest absent; subpetiolar process absent. Postpetiole slightly broader than petiole in dorsal view; dorsal outline largely convex in profile; ventral outline slightly projected with acute anterior apex.

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

Head with irregular rugae which are thin; ventrolateral portion feebly sculptured but shining. Clypeus smooth and shining. Mesosoma with waved rugae which are thin and longitudinal. Forecoxa smooth and shining. Petiole and postpetiole weakly sculptured. First gastral segment smooth and shining. Head with extremely dense, and relatively long pilosity on dorsum. Mesosoma with extremely dense, and relatively long pilosity on dorsum, hairs of pronotum much longer than propodeal spine. Petiole without hairs on ventral surface. Postpetiole with 8 hairs on ventral surface. Body yellow.
