Head and mesosoma with long, fine, predominantly longitudinal rugulation; mandibles almost entirely smooth and shining, with very short longitudinal striae restricted to the most basal portion; rugae transverse on anterior portion of pronotum, grading to longitudinal on rest of mesosoma; lateral surfaces of pronotum, meso and metapleura, dorsum of propodeum, coxae, and waist coarsely punctate. Pilosity very long, slightly denser on appendages; dorsum of petiole and postpetiole each with around eight long hairs; first tergite of gaster sparsely covered by long flexuous hairs.</paragraph>

Mesosoma considerably slender; promesonotum moderately convex in profile, but well above propodeum level; metanotal groove shallow and broad, with an ill definite posterior limit; propodeal spines straight and very long, about two times longer than the distance between its bases; teeth of propodeal lobes well developed and acute, with little less than propodeal spines half-length. Petiole elongate, around three times longer than broad in dorsal view; petiolar node low, dorsally rounded, and with posterior margin only minimally sloped in lateral view; postpetiole with dorsal surface convex and ventral surface without projections.</paragraph>

<typeStatus id="8E0E912542DDD34D7307A8644731420A">holotype</typeStatus>
