Morphology

Soldier

The soldier has the head reddish brown, slightly deeper near the anterior margin; labrum pale yellowish brown, mandibles nearly black and slightly paler at the base; the anterior part of the postmentum pale reddish brown and the posterior part yellowish brown; antennae pale yellowish brown, pronotum yellowish brown, mesonotum and metanotum pale yellowish white. Head rectangular, the sides nearly parallel, widest at the middle or near the back of the head, the posterolateral angles broadly rounded, the posterior margin almost straight; the two frontal lobes only very slightly raised, in profile the frontal slope about 45 degrees, the eye spots behind the antennal sockets extremely indistinct. Mandibles slightly more than half the length of the head, stout in the posterior half, rather sharp and slightly curved at the front, the basal tubercle of the mandible distinct. Left mandible with four marginal teeth: the first and second triangular and of about equal size with their tips slightly forwards; the third largest and directed inwards, farther from the preceding marginal tooth; the fourth small. Right mandible with two large triangular marginal teeth, both directed inwards. Antennae with 10–11 segments. Pronotum kidney-shaped, flat, the anterior margin shallowly concave with the anterolateral angles projecting forwards, the lateral margins arcuate, the posterior margin a broad arc, both anterior and posterior margins with a small median notch, the median longitudinal line on the surface distinct.

Alate

Alate head nearly blackish brown, labrum yellowish brown, clypeus yellow, antennae pale brown, compound eyes nearly black, ocelli pale brown, thoracic tergites nearly blackish brown, abdominal tergites reddish brown, femora brown, tibiae and tarsi pale yellowish brown. Head slightly square, the anterior margin a shallow concave arc, the lateral margins rather parallel from the front to the posterior margin of the compound eyes, the posterior margin of the head nearly semicircular between the two compound eyes; in profile the frontal surface rather steep, the Y-shaped suture on the vertex very indistinct. Compound eyes nearly circular, moderately bulging; ocelli also nearly circular, rather close to the compound eyes. Labrum nearly a transverse square, its anterior margin slightly arcuately projecting. Antennae incomplete, the second slightly short, the third longer, the fourth slightly shorter than the third and slightly larger than the second. Pronotum kidney-shaped, as wide as the head including the compound eyes or slightly wider, the anterior margin a shallow concave arc, the lateral margins convex-arcuate, the posterior margin broadly arcuate with a slight median concavity, the median longitudinal line on the surface groove-like, the anterior and lateral margins with sparse short hairs, the posterior margin with slightly denser short hairs. The forewing scale very large, covering almost the whole hindwing scale.
