Worker
Bolton (2000) - TL 1.1-1.4, HL 0.40-0.46, HW 0.36-0.40, CI 82-95, ML 0.12-0.14, MI 27-33, SL 0.20-0.24, SI 55-63, PW 0.20-0.24, AL 0.42-0.48 (measurements from Ogata, 1990). Apicodorsal tooth of mandible short-spiniform, longer than apicoventral tooth. Mandible without preapical teeth. Dorsal surface of mandible bare, without longitudinal rows of broad specialised hairs. Anterior clypeal margin with 6 narrowly spoon-shaped hairs; the two pairs closest to the clypeal midline are short and curved or inclined toward the midline. Hairs on leading edge of scape are curved toward the base of the scape. Funicular segments 2 and 3 ( = antennal segments 3 and 4) small but distinct. Orbicular hairs present on dorsal surfaces of scapes and all over the cephalic dorsum; those occurring medially on the clypeus are the same size as those near its lateral or posterior margins. CI < 1 00. Mesonotum in profile not bulging posteriorly over base of propodeum. Dorsolateral margin of propodeum without broadly spoon-shaped hairs that are strongly curved posteriorly.
