Soldier. Head and pronotum sparsely hairy; postmentum with several long hairs. Head subcircular, considerably narrowed anteriorly, bHW / mHW 0.50–0.55 (0.52); mandibles weakly incurved, LML / HL 0.57–0.63 (0.59). Antennae with 13–14 segments. Narrowest part of postmentum located about one-third of the distance from the posterior margin to the widest point.

Measurements (mm)

Eleven soldiers from three series: HL, 1.04–1.20 (1.10); mHW, 0.94–1.01 (0.97); LML, 0.61–0.74 (0.65); PL, 0.35–0.40 (0.37); PW, 0.60–0.73 (0.65); PosL, 0.61–0.70 (0.65); PosW, 0.29–0.34 (0.31).
