Description
Worker
Holotype. TL 2.84 (head separated), HL 0.68, HW 0.61, CI 89, SL 0.56, SI 92, PW 0.38, ML 0.82.
Head subrectangular, slightly longer than broad in full-face view; median portion of occipital margin slightly concave; occipital corners rounded, not projected posteriorly. Masticatory margin of mandible straight; apical tooth strong, third tooth robust, followed by 6 small teeth. Dorsal surface of clypeus slightly concave; median portion of anterior margin much projected with distinct three processes; 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 mediumsized and moderately convex with maximum diameter 0.10 mm, with 6 ommatidiain the longest row; 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 or longer. Antennal scape short, just reaching posterolateral corner of head; antennal flange fully developed.
Dorsal outline of mesosoma slightly convex in profile. Pronotum without denticles; anterior portion not marginate; anterior ventrolateral portion not angulate. Furrow between pronotum and mesoepisternal projection relatively narrow. Eumetanotal spine present but small. Propodeal spine triangular, length as long as broad at base, not reaching vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle large, situated near base of propodeal spine, distance between posterior margin of spiracle and posterior margin of propodeum much longer than diameter of spiracle. Petiole short, length as long as high in profile, longer than broad in dorsal view; dorsal crest located slightly at anterior portion in profile; subpetiolar process reduced. Postpetiole slightly broader than petiole; lateral margin straight; anterior portion slightly raised in profile; ventral outline slightly projected rectangularly.
Anterior margin of gaster not concave in dorsal view; first gastral sternum simple without median longitudinal ridge.
Head with weakly waved rugae; ventrolateral portion smooth and shining. Clypeus smooth and shining. Mesosoma with weakly waved rugae. Forecoxa smooth and shining. Petiole and postpetiole with a few rugae. First gastral segment smooth and shining. Head with relatively sparse and short pilosity on dorsum. Mesosoma with sparse 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. Head and mesosoma black, antennal scapes, petiole, postpetiole and gaster reddish brown, mandibles, antennal funiculus and legs yellowish brown to reddish brown.
