Soldiers. Head: in dorsal view head capsule excluding rostrum pale yellow to yellow; rostrum darker than head capsule; antenna slightly paler than head capsule in coloration. Head with three or four scattered bristles, tip of nasus a hairs and four bristles, pronotum and abdominal tergites with hairs and brittles. In dorsal view head capsule round; its posterior margin roundly convex in the middle; dorsal outline of head capsule (including rostrum) in profile nearly straight. Antenna with 13 articles; second and fourth almost equal in length; third clearly longer than fourth; fourth shorter than fifth. Thorax: pronotum seen from above paler than head capsule in coloration; its periphery darker than central area. Coxae and femora pale yellow; tibiae whitish. Anterior and posterior margins of pronotum nearly straight in the middle. Abdomen: tergites yellow to pale brown.

Soldiers (n = 10; (size range) in mm): head length including nasus (HLN) (2.10-2.20); head length measured to base of mandible (HL) (1.07-1.25); nasus length (NL) (0.92-1.07); nasus index = NL/HL (0.85-0.86); maximum head width (HW) (1.23-1.32); maximum height of head excluding postmentum (HH) (0.80-0.83); pronotum length (PL) (0.20-0.23); pronotum width (PW) (0.56-0.60).

Workers. Antenna: pale yellow to yellow; 14 articles; second much longer than fourth; third longer than fourth; fourth the shortest. Left mandible: apical tooth shorter than first marginal tooth; third marginal moderately protruding from cutting edge; fourth completely hidden behind molar prominence.
