Morphology

Soldier

The head capsule and antennae are yellowish brown, the labrum, thorax and abdomen yellowish white, the mandibles dark brown, the left mandible paler and reddish brown. The head capsule is rectangular, distinctly narrowed in front of the antennal sockets, the sides slightly convex, the posterolateral corners broad and rounded, the middle of the posterior margin shallowly concave; the median suture extends forwards from the posterior margin beyond the midpoint of the head capsule, the fontanelle pore-like with its posterior margin sclerotised and brownish. In lateral view the frontal ridge is not raised and the slope gentle, and behind the fontanelle a blunt ridge runs towards the lateral corners. The labrum is slightly longer than wide, the anterior margin almost straight. Antennae with 14 segments, segments 2 and 4 about equal and both shorter than segment 3. The mandibles are asymmetrical and shorter than the head; the posterior part of the left mandible is upturned and twisted inwards, its apex forming a hook, with a basal tooth and a basal process on the inner margin; the right mandible is blade-like with a pointed apex. The postmentum is long and cup-shaped, widest immediately behind the anterior margin, narrowest at one-quarter from the posterior margin; in lateral view the postmentum bulges out of the ventral surface of the head. The pronotum is saddle-shaped, the anterior, lateral and posterior margins bearing respectively one to three pairs, five pairs and one pair of long hairs, the anterior and posterior lobes nearly vertical, both the anterior and the posterior margin with a median notch. Tibial spur formula 3:2:2.
