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

The soldier has the head chestnut brown, the front and the postclypeus deep brown, the transverse ridge adjacent to the dorsal articulation of the mandibles black; mandibles reddish black, eye spots slightly paler than the head, the lateral margins of the postmentum deep brown; pronotum pale brown with a fine dark border all round; the body very sparsely haired. Head rectangular, cylindrical, the lateral margins straight and parallel, the posterior margin rather straight. At the junction of the frons and the vertex there is a pair of inverted-V-shaped mound-like elevations with a groove between them, their two outer ends directed towards the antennal sockets and extending only halfway to them; the Y-shaped suture very indistinct. Left mandible with four marginal teeth, the first and second adjacent, followed by a blunt concavity, the third largest, the fourth broad and low; right mandible with two marginal teeth of almost equal size, their tips directed backwards. Antennae with 13–14 segments. Postmentum rather slender, its widest part 2.5 times the narrowest. Pronotum very broad and flat, about twice as wide as long, with a groove in the anterior half of the median axis, the anterior margin slightly concave with a very indistinct median notch, the lateral margins semicircular and arched downwards, the posterior margin arcuate with a shallow median concavity.

Alate

Alate head capsule brown, antennae, labrum, anteclypeus and legs greyish brown, compound eyes slightly paler than the head or deep brown, ocelli and antennal spots pale; pronotum apparently paler than the head, the abdomen paler than the thorax, femora and tibiae greyish yellow, wings pale brown, sparsely haired. Head circular, slightly long, compound eyes subcircular, their diameter greater than their distance to the lower margin of the head, projecting on the two sides of the head; ocelli small and raised as round dots, clearly separated from the compound eyes; antennal spots small and nearly semicircular, situated in front of and inside the ocelli. Antennae with 14 segments, the second and third equal, the fourth shortest. Labrum flat and square, clypeus broad and flat. Each mandible with two marginal teeth. Postmentum elongate. Pronotum as wide as the head or slightly narrower, the anterior margin concave without a median notch, the posterior margin continuous with the lateral margins in an arc. Wings narrow and long, the wing surface with distinct warts; the media of the forewing strongly sclerotised, close to and parallel with the radius sector, the distance from the radius sector to the media equal to that from the radius sector to the costal margin, the radius sector almost unbranched.
