Morphology

Soldier

Head of the soldier yellowish brown, mandibles dark brown and red-brown at the base, labrum darker, anteclypeus pale yellow, antennae yellowish brown. Body small. Head capsule wide and short, nearly rectangular, the lateral margins nearly parallel, the posterior margin broadly rounded, the front of the frons slightly inclined, with a shallow concavity in the middle. Eyes oval, semi-transparent. Antennae damaged with only ten segments remaining, the antennal socket process well developed, not reaching the first segment; segment 3 slightly longer than segment 2 or nearly equal, segment 4 shortest. Postclypeus nearly rectangular, the anterior margin with long hairs; anteclypeus short and wide, trapezoidal; labrum nearly square, the anterior margin rather straight, with a few long hairs on the anterior margin and the surface. Mandibles rather slender, about two thirds of the head capsule (to the mandibular base), the base slightly swollen, the outer margin rather straight, the apex slightly curved inwards; the inner margin of the left mandible, apart from the apical tooth, with five marginal teeth, the first and second nearly triangular and almost equal in length, the third and fourth short and blunt with a shallow notch between them, the boundary between the fourth and fifth indistinct; the inner margin of the right mandible with two marginal teeth, slightly wavy between the first tooth and the apical tooth, the two teeth nearly triangular. Postmentum wide and short, the anterior end distinctly wider, the posterior end narrower, the anterior margin nearly straight, the posterior margin slightly convex. Pronotum nearly rectangular, with sparse long hairs, slightly wider than the head capsule, the anterior margin deeply V-shaped in the middle, the anterior lateral corners slightly pointed, the posterior lateral corners broadly rounded, the posterior margin nearly straight. Legs slender, tibial spur formula 3:3:3, tarsi 4-segmented.

Alate

Head of the worker milky yellow, labrum and antennae milky white, abdomen and legs milky yellow. Head nearly circular, the eye marks distinct, nearly circular. Antennae with 13 to 16 segments, densely covered with fine hairs. Postclypeus nearly rectangular, the anterior margin with several long hairs; anteclypeus nearly trapezoidal; labrum nearly square, with hairs on the anterior margin and the dorsum. The left mandible with an apical tooth and two marginal teeth, the apical tooth slightly longer than the marginal teeth, the two marginal teeth almost equal in length; the right mandible also with an apical tooth and two marginal teeth, the apical tooth nearly equal in length to the first marginal tooth, the second marginal tooth slightly shorter. Pronotum nearly rectangular, as wide as or slightly wider than the head capsule, the anterior margin shallowly and broadly concave, the posterior margin nearly straight. Legs rather slender and short, the apex of the tibia with three spurs, apical tibial spurs 3:3:3, tarsi 4-segmented.
