Description
Worker
Holotype. HL 0.68, HW 0.60, SL 0.54, PW 0.40, ML 0.94, PL 0.20, PH 0.20, ESL 0.12. Paratype workers. HL 0.66-0.70, HW 0.58-0.62, SL 0.53-0.55, PW 0.38-0.42, ML 0.90-0.94, PL 0.19-0.20, PH 0.19-0.20, ESL 0.10-0.12 (4 specimens measured).
Head longer than broad (CI 1.13), with slightly convex sides and almost straight occipital margin. Anterior clypeal margin broadly rounded. Antennae 12-segmented, antennal scape relatively long, almost reaching occipital margin (SI1 = 0.78-0.80, SI2 = 0.88-0.93).
Mesosoma in profile with gently convex pronotum, flat mesonotum and posteriorly inclined propodeum. Metanotal groove indistinct. Propodeum with short, basally widened, sharp spines (ESLI = 0.17-0.20). Humeri in dorsal view distinctly angulate. Petiole as long as high (PI = 1.00), with long anterior peduncle; petiolar node in profile with distinct concave anterior face and broadly rounded dorsum. Postpetiole as high as petiole, subglobular.
Dorsum of head with fine striations, which are very feeble in the central area of the frons. Area between frons and eyes finely reticulate. Anterior margin of pronotum marginate, pronotum with concentrated fine striations, mesonotum and propodeum with short, transverse striations. Sides of pronotum with longitudinal rugosities, mesopleura and propodeum coarsely punctuate. Whole mesosoma appears dull. Petiole finely punctuate, postpetiole and gaster smooth and shining.
Occipital margin and dorsum of mesosoma with sparse, moderately long, slightly curved standing hairs. Antennae, mesosoma, petiole, postperiole and legs brownish-yellow, head and gaster dark brown.
