Description

Queen

Robust, with thick, smooth integument. Head very high and convex in the middle, depressed at the posterior corners, which are rounded; the occiput deeply excised in the middle. Eyes very prominent but rather small, situated at the sides of the head and just in front of its middle. Ocelli large and prominent. Palpi very small and short. Mandibles well-developed, subtriangular, dentate, narrow at the bases which are inserted rather far apart near the anterior corners of the head. Clypeus broad and short with nearly straight anterior border; its posterior border straight and not continued back between the frontal carinre. The latter very short and neither prominent nor covering the antennal insertions, sigmoidal, moderately far apart. Antennre 12-jointed, long, inserted very close to the clypeus; scape stout, funiculus very slender, not thickened towards the tip; first joint shorter than the second. Antennal and clypeal fovere not confluent, the latter indistinct. Thorax robust and massive, broader than the head; mesonotum very prominent anteriorly, epinotum smooth and unarmed, its spiracles circular. Petiole large, with a very thick, rounded node above. Gaster short and subglobose, not longer than broad, very convex above; first segment short, not longer than the second and third together. Legs very long; femora, tibire and metatarsi flattened; spurs of posterior tibire very small and short. Claws simple. Wings lacking.
