Head with a few number of scattered bristles, tip of nasus with four bristles, pronotum hairs, abdominal tergites with hairs and brittles. In dorsal view head capsule round; its posterior margin nearly straight in the middle; dorsal outline (including rostrum) in profile nearly straight, down-curved apically. Antenna with 13 articles; second slightly longer than fourth; third the longest; fourth shorter than fifth. Thorax: pronotum seen from above paler than head capsule in coloration; its anterior part darker than posterior part. Coxae and femora sepia brown; tibiae yellowish. Anterior margin of pronotum moderately indented in the middle; posterior margin nearly straight in the middle. Abdomen: tergites yellowish to pale brown.

Soldiers (n = 10; (size range) in mm): head length including nasus (HLN) (2.05-2.18); head length measured to base of mandible (HL) (1.20-1.25); nasus length (NL) (0.82-0.95); nasus index = NL/HL (0.68-0.76); maximum head width (HW) (1.37-1.50); maximum height of head excluding postmentum (HH) (0.90-0.95); pronotum length (PL) (0.25-0.30); pronotum width (PW) (0.60-0.70).
