Worker
Holotype. TL 3.6, HL 0.74, HW 0.73, CI 99, SL 0.97, SI 133, PW 0.45, AL 1.06, EL 0.23. Paratypes (n=27). TL 3.6–4.0, HL 0.73–0.79, HW 0.70–0.78, CI 95–99, SL 0.94–1.06, SI 132–136, PW 0.45–0.52, AL 1.01–1.25, EL 0.20–0.23.

Head slightly longer than broad, sides and posterior margin convex, posterior corners rounded. Anterior clypeal margin sinuous, shallowly notched in the middle, without longitudinal carina. Mandibles with 6 teeth, the 3rd slightly smaller than the 4th, and the 5th very reduced. Eyes convex, moderately large, placed behind the mid length of head; Antennae stout and long, scapes extending about 1/2 of their length beyond posterior margin of head. Frontal carina short, reaching to anterior margin of eyes. Mesosoma slender, strongly medially constricted; metanotal groove conspicuous; in lateral view pronotum and mesonotum together form a convexity, propodeum low, with declivous face slightly longer than dorsal face, posterodorsal corner angulate. Petiolar node low, subtriangular in lateral view. Gaster about two times longer than head, gibbous.

Mandibles, clypeus, head, and mesonotum smooth and shining, constriction of mesosoma with sparse coarse longitudinal rugae, mesopleuron and propodeum with fine longitudinal striations, and the latter combined with reticulations. Petiole and gaster smooth and shining. Dorsum of head and gaster with several soft long setae, combined with a few short setae. Setae on mesosoma: pronotum 0–4, mesonotum 0–4, propodeum 0–6, and petiolar node 0–2 (number of setae different in individuals: specimens collected from Hunan with abundant setae on whole body). Mesosoma, petiole, antennae, and legs yellow to yellowish brown, head and gaster black.
