Morphology

Soldier

The front of the head blackish brown, the posterior part reddish brown, mandibles black, labrum and antennae yellow, pronotum yellowish brown, abdomen pale brown. Labrum with a pair of apical hairs and a few short hairs. Head short and thick, longer than wide; the middle of the anterior margin of the frons concave backwards and inwards, the lateral margins distinctly concave beside the eyes in dorsal view, the posterolateral margins broadly rounded, the back of the head rather raised. A horn-like process above and below each antennal socket, the tip of the lower longer than that of the upper. Mandibles stout, broad and flat, the outer margin distinctly swollen near the base, the inner margin with two marginal teeth, the distance between the tips of the two teeth of the left mandible rather large, that of the right smaller. Labrum short and broad, its tip slightly pointed. Eyes pale, oval. Postmentum nearly square, the anterolateral angles arcuate. Antennae with 12–13 segments, the second rather long, the fourth shortest. The lateral margins of the pronotum broader in the anterior part, the posterolateral angles distinctly contracted into an arc, the posterior margin rather narrow, the median notch of the anterior margin obtusely angular, broad and deep, the concave edge smooth.

Alate

Head and pronotum yellowish brown, anteclypeus pale yellow, postclypeus yellow, abdomen pale yellow. Labrum with a few long hairs. Body rather small. Head nearly rectangular, the sides nearly parallel, longer than wide; compound eyes oval, projecting from the sides of the head; ocelli nearly round, rather far from the compound eyes. Labrum slightly broad, arched spherically; the middle of the anterior margin of the anteclypeus slightly concave, its surface wrinkled. The apical tooth of the mandibles long and sharp, the inner margin with two marginal teeth, the posterior margin of the first marginal tooth of the left mandible shorter than the anterior margin of the second marginal tooth, the posterior margin of the second marginal tooth of the right mandible longer than the molar plate. Antennae generally with the second segment longer than the fourth and the third shortest. Pronotum slightly narrower than the head, the lateral margins slightly broader before the middle, the anterior notch broad and deep, the middle of the posterior margin slightly concave. The forewing scale rather long, completely covering the hindwing scale. Hind tibia short, tarsi with four segments, the spur formula 3:3:3, with an arolium between the claws.
