Holotype. HL 0.60, HW 0.54, SL 0.52, PW 0.42, ML 0.88, PL 0.20, PH 0.18, ESL 0.12, Head longer than broad (CI = 1.10- 1.15), with convex sides, almost straight occipital margin. Anterior clypeal margin broadly rounded. Antennae 12-segmented, antennal scape relatively long, slightly surpassing occipital margin (SI1 =0.86-0.94, SI2=0.96- 1.03).

Mesosoma with strongly convex pronotum, in profile its anterior face steep. Metanotal groove shallow and indistinct. Propodeum with short, basally wide, sharp spines (ESLI = 0.18-0.22). Humeri in dorsal view distinctly angulate. Petiole slightly longer than high (PI = 1.10-1.11), 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, spaces between striations finely reticulate, central part of frons unsculptured, appearing smooth. Anterior margin of pronotum marginate, its central plate smooth, mesonotum irregularly longitudinally striate, dorsum of propodeum transversely rugulose. Sides of pronotum longitudinally rugulose, mesopleura and sides of propodeum longitudinally rugulose and coarsely punctuate. appearing dull. Petiole finely punctuate, postpetiole dorsum and gaster smooth and shining.

Occipital margin and dorsum of mesosoma with fine, short standing hairs. Body and appendages ochreous-yellow, dorsum of head and gaster darker.
