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

In the soldier one antennal segment is incompletely divided, thus forming a longer segment. The anterior and posterior halves of the pronotum almost equal in width, the anterior part erect or slightly inclined backwards, the anterior margin without a median notch.

Alate

Head of the alate brown, antennae, labrum and postclypeus yellow; pronotum paler than the head and with a yellow T-shaped marking; anterior part of the mesonotum and metanotum yellow, the posterior part brown; dorsum of the abdomen brown, the ventral surface slightly yellow; wings semi-transparent, pale blackish brown, the veins darker. Head and pronotum densely covered with hairs. Head broadly oval, with a pit in the middle of the vertex, fontanelle small and slit-like. Antennae with 15 segments, segment 3 smallest, segment 2 smaller, segments 4 and 6 nearly equal in length. Compound eyes small and round, ocelli oval, the ocellus-compound eye distance about equal to the length of the ocellus; postclypeus arched, the anterior margin nearly straight, the posterior margin bowing out. Pronotum narrower than the head, 1.5 times as wide as long, the anterior margin nearly straight and slightly raised, the middle of the posterior margin notched. Media of the forewing unbranched or with one to three branches, situated close to the cubitus, the cubitus with eight to ten oblique branches; media of the hindwing arising from the radial sector behind the humeral suture, the rest as in the forewing.

Worker

Head of the worker yellow, abdomen almost white. The head with a few short hairs, the dorsum of the abdomen densely covered with short hairs, the ventral surface also with short hairs, the posterior end of each segment with a row of long hairs. Head oval, the vertex flat, the dorsum with a pale T-shaped marking; total length 4.72 to 5 mm, postclypeus slightly arched, about one third as long as wide. Antennae with 14 segments, segment 4 shortest, segments 2 and 3 about equal in length. Anterior part of the pronotum erect, the anterior margin deeply notched in the middle.
