Worker
Bolton (2000) - TL 2.4-2.6, HL 0.72-0.78, HW 0.50-0.53, CI 65-69, ML 0.04-0.06, MI 5-8, SL 0.35-0.40, SI 68-73, PW 0.28-0.30, AL 0.72-0.76 (6 measured). With head in profile the anterior margin of the clypeus curving upward, away from the dorsal surface of the mandible. In full-face view clypeus expanded laterally and its lateral margins convex, so that the outer margins of the mandibles are mostly overhung and concealed; a narrow but distinct notch is present between clypeus and frontal lobe. Frontal lobes and frontal carinae strongly expanded laterally, the preocular carinae not visible. Lateral edges of upper scrobe margins distinctly sinuate in full-face view. Frontal carinae with two fenestrae on each side behind the small fenestra that lies directly above the antennal insertion. Frontal carina posteriorly, behind the level of the posterior fenestra, curving medially and apically angled inward onto the vertex just in front of the occipital margin. In profile this carinal extension very conspicuous, curving toward the cephalic midline above and behind the apex of the scrobe. Vertex smooth and shining. Apicoscrobal hair and pronotal humeral hair flagellate; 2 pairs of flagellate hairs present on the mesonotum. Dorsal alitrunk, waist segments and first gastral tergite with fine pilosity that is simple to short-flagellate; dorsal (outer) surfaces of middle and hind tibiae with short subdecumbent to suberect fine projecting hairs. Pronotum with longitudinal rugulose sculpture and a median carina. Basigastral costulae sharp and conspicuous.
