Body and appendages reddish to dark brown, contrasting with darker gaster. 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.
