Morphology

Soldier

The head is yellow, the thorax and abdomen pale yellowish white. The head capsule is rectangular, the head width index 0.55–0.59, the sides nearly parallel or slightly expanded posteriorly; in lateral view the frontal ridge is very slightly raised. The labrum is spear-shaped, slightly longer than wide, the semi-transparent apical region narrow and rounded, a pair of short subapical hairs behind the apical hairs, the lateral-apical hairs absent, and a few bristles occasionally seen on the labral ridge. The mandibles are somewhat short and stout, the mandibular length 0.85–0.89 times the head width and not reaching half the head capsule length, the apices rather strongly curved, the basal ridge of the outer margin indistinct. The lacinial margin of the maxilla with nine to ten hairs. The waist constriction index of the postmentum 0.28–0.30. Antennae with 16 segments. The pronotum is about 1.5–1.7 times as wide as long, the notch of the anterior margin deeper than that of the posterior, the median notch rate 6–11 per cent, with about twenty hairs in the middle region.

Alate

The whole body is lemon yellow, the compound eyes purplish brown, the wing scales yellowish brown, the wing surface pale greyish brown. The body hairs are golden yellow. The head capsule is oval, the vertex rather flat; the postclypeus projects, its height equal to that of the vertex. The long diameter of the compound eye is greater than the distance from the compound eye to the lower margin of the head, the projection rate 3–6 per cent. The ocelli are rather large, the ocellus-compound eye distance about half the long diameter of the ocellus; the distance from the ocellus to the antennal socket is almost equal to that from the compound eye to the antennal socket. The fontanelle is a pale yellow dot, slightly projecting. Antennae with 14 segments. The pronotum is about 1.4–1.6 times as wide as long, the anterior margin slightly raised, the middle of the posterior margin slightly concave, the notches of the anterior and posterior margins almost equal, the median notch rate 8–16 per cent, the pilosity very dense. The cubitus of the forewing and of the hindwing each has about ten branches.
