Recorded in Fauna Sinica

The morphological and biological accounts below are taken from Fauna Sinica and related literature; only structure and punctuation have been standardized here.

Morphology

Soldier

Large form: head and thorax pale yellow, antennae yellow, the nasus and the raised part of the pronotum brown; head with 3–4 long hairs, the dorsum of the thorax and abdomen almost hairless. Head like a transversely placed ellipse, wider than long, widest in the middle, the sides narrowly rounded, the posterior margin broadly rounded. Nasus stout, slightly upturned in profile, the tip somewhat inclined downwards yet higher than the dorsum of the occiput, concave in the middle; the apical spine of the mandibles short and small. Antennae 13 segments, the third twice the second or more, the second the shortest. Tibial spurs 2:2:2, tarsi 4-segmented. Small form: colour as in the large form, the tip of the nasus with a few hairs, the body almost hairless; head nearly circular, slightly longer than wide, the nasus straight in profile with the tip slightly lower than the occiput, the spine at the lateral end of the mandible point-like; antennae 12 segments, the third about twice the second; the incisions of the anterior and posterior margins of the pronotum both indistinct.

Alate

Worker

Antennae of the worker: the third segment twice the second or longer, the second the shortest. The anterior half of the pronotum erect and raised, meeting the posterior half at a right angle, the incision of the anterior margin distinct, the posterior margin slightly concave. Tibial spurs 2:2:2, tarsi 4-segmented. The apical tooth of the left mandible distinctly longer than marginal tooth 1, and the apical tooth of the right mandible also slightly larger than marginal tooth 1; marginal tooth 2 rather close to marginal tooth 1, the molar plate with eight grooves.
