Morphology

Soldier

Major soldier: head capsule nearly reddish brown, mandibles dark brown with a reddish brown base, antennae pale yellow, pronotum yellowish brown, mesonotum, metanotum and abdomen paler, head and pronotum almost hairless. Head almost trapezoidal, the posterior margin broadly rounded, in lateral view the middle of the dorsal margin slightly raised; fontanelle near the centre, dot-like and sunken, the eye spot small and distinct; labrum ligulate, slightly convex in the middle of each side, the apex of the transparent area rather pointed; mandibles stout with the apex incurved, the base of the inner margin of the left mandible with an incision, the fine teeth below the midpoint indistinct; postmentum nearly rectangular, the waist region almost parallel; antennae with 17 segments, segment 3 about twice segment 2. Anterior margin of the pronotum deeply concave with a median incision, the posterior margin also deeply concave, the lateral lobes narrow and rounded; posterior margin of the mesonotum deeply concave, that of the metanotum nearly straight. Minor soldier: head reddish brown, mandibles reddish brown, antennae yellowish brown; head nearly rectangular, slightly narrower in front; eyes small and oval; mandibles slender and straight with the apex incurved, the base of the inner margin of the left mandible with an incision but without fine teeth. Pronotum widest, the anterior margin broadly rounded and shallowly concave in the middle; mesonotum narrowest; hind tibia longer than the head width.

Alate

Head nearly reddish brown, postclypeus and ocelli pale yellowish brown, thoracic tergites reddish brown, abdomen paler; head with sparse long hairs and almost hairless on the posterior margin, the anterior and lateral margins of the pronotum also with sparse long hairs, the dorsum with both long and short hairs apart from indistinct maculae. Head distinctly wider than long, the posterior margin broadly rounded; fontanelle at the centre of the dorsum, circular and projecting; compound eyes relatively large, elliptical and prominent; ocelli oval, slightly convex, their distance to the compound eyes distinctly less than the short diameter of the ocellus; postclypeus markedly arched, with a longitudinal line at the centre of the dorsum, the anterior margin bearing a pair of long hairs; the anterior margin of the anteclypeus slightly convex in the middle; labrum ligulate, the anterior margin nearly flat; left mandible with two marginal teeth.
