Bolton (1977) - Holotype. TL 3.8, HL 0.90, HW 0.84, CI 93, SL 0.62, SI 74, PW 0.58, AL 1.04.

Mandibles striate; anterior clypeal margin entire but exceedingly shallowly concave medially. Frontal carinae extending back almost to occipital corners but behind level of eyes becoming very weak, scarcely or not more strongly developed than the other cephalic sculpture. Antennal scrobes shallow and broad, only feebly developed. Occipital margin of head distinctly concave medially in full-face view. Eyes moderate, maximum diameter c. 0'19, the eyes situated in front of the middle of the sides of the head. Dorsal alitrunk evenly, shallowly convex in profile, the propodeal spines long, thick, acute and feebly sinuate along their length, the apices very weakly upcurved. Metapleural lobes narrowly triangular and acute. Shape of petiole in profile as shown in Fig. 51; in dorsal view the node distinctly longer than broad. Dorsum of head predominantly longitudinally rugose with very few cross-meshes to the level of the posterior margins of the eyes, behind this a strong reticulum is developed. Dorsal alitrunk reticulate-rugose. Sides of petiole node with some weak rugosity but the dorsum with an un sculptured median longitudinal strip. Postpetiole and gaster unsculptured. All dorsal surfaces of head and body with quite short erect or suberect hairs. Leading (anterior) margin of antennal scapes with pubescence and also with a spaced row of short, erect hairs. Dorsal (outer) surfaces of hind tibiae with short erect or suberect hairs. Colour reddish brown, the legs dull orange-brown.

Paratypes. As holotype but some slightly lighter in colour, dull orange-brown. Measurements TL 3.3-4.0, HL 0.80-0.98, HW 0.72-0.90, CI 90-94, SL 0.54-0.64, SI 69-75, PW 0.52-0.64, AL 0.90-1.12 (21 measured).
