Morphology

Soldier

The soldier has the head brownish yellow, the frontal slope turning brown towards the front, mandibles reddish brown with the anterior two-thirds nearly black, pronotum brownish yellow with a pale median line, thorax and abdomen pale yellow, legs pale yellow. Head rectangular, about 1.5 times as long as wide, the sides nearly parallel, the posterolateral angles arcuate, the posterior margin straight; the Y-shaped suture present but indistinct, the frontal slope about 45 degrees, the upper end of the slope slightly depressed in the middle, the two frontal lobes only very slightly raised. Mandibles stout, swollen at the base. Left mandible with four large marginal teeth: the first directed forwards, the second shorter, the third and fourth broad, short and directed inwards, situated behind the midpoint. Right mandible with two, the first near the midpoint, the second broad and large, situated at the basal third. Labrum short, wider than long. Antennae with 10–11 segments, mostly 11, the second larger than the third and smaller than the fourth, from the fourth onwards obconical. Pronotum slightly narrower than the head, the anterior margin a shallow arc with a slight median concavity, the sides curved towards the venter, the posterior margin narrow and straight with a slightly concave midpoint; mesonotum and metanotum with small wing pads.

Alate

Alate head deep reddish brown, labrum dull yellow, clypeus pale yellow, antennae deep yellow, compound eyes nearly black, ocelli yellow; pronotum reddish brown with a faint pale median suture; mesonotum and metanotum brown, their anterior halves with a black median longitudinal line; wing scales and wing veins the same colour as the pronotum, legs brown with tibiae and tarsi pale brown, the colour of the abdominal tergites close to that of the thoracic tergites. Head approximately oval, the sides slightly parallel, slightly longer than wide, the Y-shaped suture indistinct; compound eyes rather large, moderately swollen and nearly circular, ocelli nearly round and close against the compound eyes. Labrum broad, its anterior margin almost straight, the anterolateral angles rounded. Antennae incomplete, the second slightly shorter than the third, the third and fourth nearly equal. Pronotum slightly narrower than the width of the head including the compound eyes, the anterior margin a concave arc with the anterior section of the median line depressed, the lateral margins curved towards the venter, the anterolateral angles narrowly rounded, the posterolateral angles broadly rounded and continuous with the posterior margin in a semicircle. The forewing scale large, the hindwing scale short and small, about half as long as the forewing scale. Abdomen elongate-cylindrical, the sternites with a linear elevation in the middle forming a median keel line running through the abdomen.
