Worker
Holotype. TL 4.2, HL 1.00, HW 0.87, CI 87, SL 0.74, SI 85, PW 0.64, AL 1.18. Maximum diameter of eye 0.23 (0.26 x HW) and with 14 ommatidia in the longest row. Mandibles unsculptured. Sculpture of head capsule feeble, consisting of scattered short longitudinal rugulae dorsally; no rugoreticulum. Weak ground-sculpture present above the eye but head capsule otherwise mostly smooth. Subocular groove incomplete, running only from base of mandible to anterior angle of eye. Dorsal alitrunk evenly convex in profile, the propodeum sloping steeply so that the spines appear to be set low down. Mesonotum unarmed. Metanotal groove absent. Dorsal alitrunk with fine superficial sculpture only. Base of first gastral tergite unsculptured. Pilosity sparse and fine everywhere, the hairs acute; only one pair present on the sloping portion of the propodeal dorsum. Colour uniform dark brown.

Paratype. TL 4.4, HL 1.00, HW 0.85, CI 85, SL 0.74, SI 87, PW 0.64, AL 1.18. Maximum diameter of eye 0.24 (0.28 x HW). As holotype but slightly lighter in shade.
