Description
Worker
Shattuck (2000) - TL 2.4, HL 0.63, HW 0.49, CI 78, ML 0.18, MI 29, SL 0.29, SI 59, PW 0.32, AL 0.61. Anterior region of head rounding gradually from the dorsal to lateral surfaces, not phragmotic. Ridges immediately in front of eyes straight or nearly so, diverging anteriorly. Frontal lobes and lateral margins of clypeus smooth relative to the surrounding surface of the head. Mandibles relatively thin and elongate, their outer margins very weakly concave. Hairs absent from dorsum of head. Posterior margin of head shallowly concave. Antenna with 6 segments, the scape elbowed and with a well developed subbasal lobe. In dorsal view the widest point of the pronotum is at the humeral angles. Propodeum high, its posterior face approximately the same height as the petiolar node and with broad, thin lamellae; in profile the pronotum and mesonotum each flat, meeting in a slight angle. Lateral postpetiole drawn outwards into thin flange-like wings, the wings with translucent windows along their posterior margins only, the windows small. First gastral tergite with weak, indistinct reticulate sculpture and a limited number of low, widely spaced carinae on the anterior one-quarter. Body colour pale honey yellow, the head very slightly darker.
