Bolton (1973) - TL 6.1, HL 1.56, HW 1.37, CI 88, SL 1.85, SI 135, PW 1.40, MTL 1.81.
Anterior clypeal margin arcuate and entire, without a rectangular median lobe. Eyes flat, nearly concave, somewhat sunk into the sides of the head. Sides of head convex, rounding into the convex occipital margin behind the eyes. Alitrunk not marginate, the dorsum rounding into the sides. Pronotum armed with a pair of short, triangular, acute spines; the propodeum with a pair of small, upcurved teeth, between which the dorsum curves evenly into the declivity. Promesonotal suture represented only by a line which breaks the sculpturation, but the metanotal groove distinct and impressed. Dorsal surfaces of the alitrunk transversely convex; the pronotum notably broader than the propodeum. Petiole armed with a pair of long dorsal, and a pair of shorter lateral spines. Anterior surface of the first gastral segment concave medially.
Head, body and appendages with numerous long, erect hairs, yellowish to off-white in colour. Pubescence greyish, densest on the alitrunk.
Clypeus superficially reticulate, head regularly and finely longitudinally striate-rugose. Dorsum of alitrunk as head, but the rugae becoming disorganised on the mesonotum and propodeum. Sides of alitrunk finely reticulate-rugose apart from the propodeum which is longitudinally striate-rugose. Gaster finely and densely reticulate-punctate.
