Morphology

Soldier

The head yellowish brown slightly tinged with smoky, mandibles reddish brown and paler at the base than in front, labrum yellowish brown, antennae yellowish brown tinged with smoky, pronotum pale yellow, abdomen and legs milky white. The head with several scattered long hairs, the labrum with nine pairs of hairs in longitudinal rows on either side from the tip to the base, the periphery of the pronotum with only a few hairs. Head nearly oval, widest at the middle, the highest point of the dorsum slightly in front of the middle. Labrum lanceolate, slightly raised in the middle. The inner margin of the left mandible with three marginal teeth, the notch between the second and third deep, two or three small serrate teeth above the first marginal tooth; the inner margin of the right mandible serrate behind the middle; the base of each mandible with a small pointed projection. Postmentum longer than wide. Antennae with 16 segments, the fourth shortest, the second about 1.5 times the third. The anterior half of the pronotum slightly constricted, the middle of the anterior and posterior margins concave.

Alate

Head broadly oval, the fontanelle distinct and slightly raised, the ocelli rather large; the postclypeus raised, its length about half its width, the posterior margin arched and the anterior margin straight; antennae with 19 segments, the third longer than the second. The posterior ends of the mesonotum and metanotum shallowly arcuately concave. The radius of the wings projects slightly beyond the wing scale; the media of the forewing arises separately at the shoulder suture, while that of the hindwing mostly arises from the base of the radius sector. The lateral walls of the abdomen of the queen bear no densely scattered coloured dots.

Worker

Workers usually occur in two size classes, large and small, and sometimes in three, large, medium and small. The sides of the head parallel or narrowed in front, the frons flat, the fontanelle dot-like; the labrum widest at the middle, with a small transparent patch at the front. Mandibles curved like a sickle, the base of the left mandible with several notches and a distinct basal tooth, the remaining parts toothless, the right mandible also toothless apart from the basal tooth. Antennae with 17 segments, the third often longer than the second. Pronotum saddle-shaped, both the anterior and posterior margins notched.
