Description.

Imago: Unknown.

Soldiers. Head: in dorsal view head capsule excluding rostrum dark brown to sepia brown; rostrum darker than head capsule; antenna much paler than head capsule. Head with combination long and short bristles, tip of nasus with short hairs and four long bristles, pronotum with short and long bristles, abdominal tergites densely with short hairs and long bristles.In dorsal view head capsule somewhat round; its posterior margin roundly convex in the middle; dorsal outline of head capsule (excluding rostrum) in profile nearly straight. Antenna with 11 articles; second shorter than fourth; third longer than fourth; fourth and fifth almost equal in length. Thorax: pronotum seen from above paler than head capsule in coloration; its periphery darker than central area. Coxae and femora yellow; tibiae whitish yellow. Anterior margin of pronotum nearly straight in the middle; posterior margin strongly indented in the middle. Abdomen: tergites dark yellow to brown.

Soldiers (n = 10; (size range) in mm): head length including nasus (HLN) (1.25-1.37); head length measured to base of mandible (HL) (0.62-0.77); nasus length (NL) (0.57-0.62); nasus index = NL/HL (0.79-0.80); maximum head width (HW) (0.77-0.80); maximum height of head excluding postmentum (HH) (0.50-0.60); pronotum length (PL) (0.12-0.15); pronotum width (PW) (0.37-0.42).

Workers. Antenna: pale yellow to yellow; 12 articles; second clearly longer than fourth; third longer than fourth; fourth shorter than fifth. Left mandible: apical tooth clearly shorter than first marginal tooth; third marginal moderately protruding from cutting edge; fourth visible in the gap between third marginal and molar prominence. Right mandible: posterior edge of second marginal tooth nearly straight; inner layer of molar plate undeveloped, and notch at proximal end of molar plate obtuse.
