Worker
Holotype. TL 3.5, HL 0.80, HW 0.74, CI 92, SL 0.64, SI 86, PW 0.52, AL 0.96.

Mandibles striate, anterior clypeal margin entire and with a narrow but quite conspicuous apron or flange anteriorly. Frontal carinae no more strongly developed than the rugose sculpture on the head, meandering and irregular, broken in places (more sharply developed in some of the paratypes). Eyes moderate, maximum diameter c. 0.16. Propodeal spines long, narrow and acute, more or less straight. Metapleural lobes elongate-triangular and acute. Petiole with a long, downcurved peduncle, the node in profile roughly rectangular in shape, the dorsum feebly but evenly convex and slightly longer than the height of the tergal portion of the node. Postpetiole more narrowly convex, dome-shaped in profile. Dorsum of head with numerous long, irregular or meandering longitudinal rugae with scattered crossmeshes posteriorly. Spaces between the rugae showing vestigial traces of superficial sculpture but for the most part smooth and shining. Dorsal alitrunk with a loose, open rugulation, the large spaces enclosed by the meshes smooth. Dorsum of petiole with an unsculptured median longitudinal strip, the sides of the node sparsely and obliquely rugose. Postpetiole and gaster unsculptured. All dorsal surfaces of head and body with numerous fine hairs, those on the dorsal (outer) surfaces of the hind tibiae suberect to subdecumbent and much shorter than the maximum tibial width. Colour uniform dark brown, the appendages yellow-brown.

Paratypes. TL 3.3-3.5, HL 0.76-0.82, HW 0.70-0.74, CI 90-92, SL 0.60-0.64, SI 81-86, PW 0.50-0.54, AL 0.92-0.98. Maximum diameter of eye 0.14-0.16 (7 measured). Mostly as holotype but in some the frontal carinae more strongly developed, running almost to the occipital margin. Colour in some a lighter brown than seen in the holotype.
