Description
Worker
Holotype. HL 0.68 mm; HW 0.54 mm; CI 79; SL 0.53mm; SI 98; WL 0.78 mm; PW 0.40 mm; PtW 0.16 mm; PtH 0.20 mm; TL 2.5 mm.
Head 1.3 times as long as wide, with feebly convex posterior margin in full-face view; sides behind eyes slightly converging posteriorly. Mandibles longitudinally rugulose. Anterior margin of clypeus moderately convex. Antennae with 12 segments; scapes long, slightly exceeding posterior margin of head in full-face view. Eyes 0.16 mm in maximum diameter.
Promesonotal dorsum feebly convex in profile. Metanotal groove shallowly incised dorsally. Propodeal dorsum flat with a small convexity near the anterior end; propodeal spines s lender and long, about 4 times as long as their basal width, and a little downcurved near the tips.
Petiole long, with long peduncle and reverse U-shaped node. Subpetiolar process a very small tooth, triangular. Postpetiole slightly longer than high; node in profile with convex anterior and straight posterior slopes; in dorsal view 1.5 times as wide as long, with convex sides and nearly straight anterior margin.
Head dorsum longitudinally rugulose, the spaces between densely punctulate. Mesosomal dorsum and pronotal sides rugose. Mesonotal and propodeal sides and petiole densely punctulate. Postpetiole more weakly punctulate. Gaster smooth and shining.
Head dorsum with stout erect hairs; mesosomal dorsum with about 14 erect hairs; the longest hair on mesosoma 0.10 mm; petiole with 2 pairs, and postpetiole with 5 pairs of erect hairs; gaster moderately abundant stout erect hairs.
Head, body, and appendages yellow.
