Worker

Chen et al. (2019) - TL 5.12–5.43, HL 1.35–1.39, HW 1.22–1.27, CI 90–92, SL 1.01– 1.04, SI 82–84, ED 0.23–0.25, PW 0.69–0.73, MSL 1.53–1.57, PL 0.031–0.33, PH 0.57–0.58, DPW 0.32–0.33, LPI 174–176, DPI 101–103 (n = 5).

In full-face view head slightly longer than broad, posterior margin strongly concave. Mandibles linear, gradually broadened apically; inner margin without denticles; apical portion with three distinct teeth. Antennae 12-segmented; scapes just reaching to posterior corners of head. Eyes large, maximum diameter wider than basal width of scape.

In lateral view mesosoma stout; pronotum convex. Promesonotal suture weakly concave dorsally. Metanotal groove in lateral view faintly impressed. Dorsum of propodeum straight, posterodorsal coner rounded. Petiole thick, distinctly higher than long, narrowing dorsally, dorsal apex narrowly rounded; anterior margin straight, posterior margin distinctly convex; subpetiolar process developed, subtriangular. Central dorsum of head and frontal lobes longitudinally striate, remainder of head smooth and shining. Pronotum and propodeal dorsum irregularly rugose. Mesonotum and propodeal declivity transversely striate. Propodeal sides obliquely striate. Mesopleuron smooth and shining. Petiole smooth and shining, basal area obliquely striate. Gaster smooth and shining.

Body dorsum with scattered suberect hairs and sparse decumbent pubescence; scapes and tibiae with dense decumbent pubescence. Body blackish brown to brown; antennae, legs yellowish brown.
