Morphology

Soldier

Head pale yellow, mandibles purplish brown, pilosity of the head capsule moderate. Head capsule rectangular, head-width index 0.56–0.59, lateral margins parallel, posterior margin broadly rounded. Frontal peaks distinctly raised, with a depression between the two peaks. Labrum lanceolate, narrow and pointed at the apex, but without a sharp tip; one apical seta and one subapical seta on each side. Mandibles rather curved at the apex, mandibular basal ridge visible; mandible length 0.48–0.53 times head capsule length and 0.83–0.88 times head width. Antennae 16–17 segments. Broad region of the postmentum about at the anterior quarter; anterior lateral margins trapezoidal, the middle section slightly concave; waist region slightly broad, margins parallel, waist constriction index 0.38–0.42. Pronotum trapezoidal, 1.46–1.55 times as wide as long, anterior and posterior margins both nearly straight, the anterior margin shallowly incised in the middle; about 20 setae in the middle region.

Alate

Head capsule light blackish brown; postmentum and femoral segments concolorous with the head; pronotum and tibiae greyish yellow; labrum and postclypeus light greyish brown; wings light brown with a blackish tinge. Head capsule roundish-square; fontanelle dot-like, about 0.48 mm from the anterior margin of the frons. Compound eyes rounded-triangular, protrusion 5–7%, short diameter greater than the distance from the compound eye to the lower margin of the head. Ocelli nearly circular; ocellus–compound eye distance equal to or slightly less than the short diameter of the ocellus. Dorsal margin of the head gently arched; postclypeus projecting, lower than the vertex, about level with the ocelli. Antennae 16–17 segments. Pronotum about 1.48–1.53 times as wide as long, anterior margin shallowly concave in the middle, posterior margin distinctly incised in the middle. Forewing 7.5–8.16 mm long, 1.91–1.99 mm wide; hindwing 7.04–7.48 mm long, 1.91–1.99 mm wide; Cu vein with about 14 branches in the forewing and about 11 in the hindwing.
