Bolton (1977) - TL 3.6, HL 0.82, HW 0.74, CI 90, SL 0.60, SI 81, PW 0.60, AL 1.02.

Mandibles finely striate; anterior clypeal margin more or less straight, without a median notch or incision. Median ciypeal carina strong, elevated, flanked by a pair of lateral carinae. Frontal carinae extended back as a narrow raised flange to the level of the posterior margins of the eyes, behind this level much weaker, confused with and no more strongly developed than the rugulae in the area. Scrobes weakly developed, consisting of a shallow, narrow groove below the frontal carinae which does not fully accommodate the scape. Eyes moderate, maximum diameter c. 0.20. Pronotal corners angulate in dorsal view, metanotal groove feeble, scarcely impressed. Propodeal spines stout and acute; metapleural lobes long and acute. Node of petiole in dorsal view as long as or very slightly longer than broad, narrower in front than behind. Postpetiole subglobular, broader than long. Dorsum of head with a number of spaced rugulae, the gaps between which have faint superficial puncturation. Rugular cross-meshes uncommon on the dorsum, more numerous and distinct in the occipital region and on the sides of the head behind the eyes. Dorsal alitrunk strongly and sharply rugose, the individual rugae raised and acute, predominantly longitudinal on the mesonotum but with strong reticulation on the anterior pronotum. Pedicel segments reticulate-rugose on the sides, the rugae fading out on the postpetiole dorsum so that the disc is predominantly shining with only one or two faint rugulae around its perimeter. Spaces between rugae on alitrunk and pedicel smooth and shining or at most with faint, almost effaced punctulation; gaster smooth, unsculptured. Long, fine hairs present on all dorsal surfaces, the longest on the alitrunk equal to or slightly longer than the maximum diameter of the eye. Colour bright orange-red, the gaster and appendages lighter, yellowish brown.

This species is apparently still known only from the holotype.
