Morphology

Soldier

Coloration paler, head brownish yellow, thoracic and abdominal tergites pale brown. Head densely covered with fine pubescence and scattered longer hairs; pronotum densely pubescent with a few scattered long hairs; abdominal tergites and sternites densely pubescent. Larger in size; head approaching rectangular, the sides almost parallel, width distinctly less than length (excluding mandibles); in lateral view the highest point of the head dorsum at the middle. Labrum ligulate and rather broad, the sides almost parallel, slightly wider than long. Mandibles rather stout, swollen at the base with the outer margin bulging outwards, the apex markedly incurved, the inner margin with a broad marginal tooth near the middle, its tip directed inwards. Postmentum large, length slightly more than twice the greatest width; widest near the anterior end, narrowest near the posterior end. Antennae with 15 segments, segments 2 and 4 equal in length, segment 3 shortest. Anterior lobe of the pronotum standing high, saddle-shaped, distinctly longer than the posterior lobe; anterior margin of the anterior lobe rather flat, posterior margin of the posterior lobe slightly concave in the middle. Tibial spur formula 3:2:2, tarsi 3-segmented.

Alate

Smaller in size; head thick and slightly convex; compound eyes very small, fontanelle distinct; postclypeus wider than the frons, the surface rather flat, length less than half the width; labrum wider than long; antennae with 15 to 16 segments. Pronotum longer than half its width. Forewing scale slightly longer than the hindwing scale, the wing surface with fine dense punctures; media of the forewing arising independently at the humeral suture, media of the hindwing arising from the radius sector, the media situated close to the cubitus. Tibial spur formula 3:2:2.
