Description
Imago: Unknown.
Soldiers. Head: in dorsal view anterior and posterior parts almost similar in coloration; except around posterior margin, much paler in coloration; rostrum darker than anterior part of head capsule; antenna paler than anterior part of head capsule in coloration. Head with two bristles, tip of nasus with four bristles, pronotum with brittles, abdominal tergites with hairs and bristles.
In dorsal view head capsule somewhat pear-shaped, strongly constricted behind antennal sockets; its posterior margin weakly indented; dorsal outline (including rostrum) in profile nearly straight. Mandible with moderately developed apical processes. Antenna with 14 articles; second longer than third; third the shortest; fourth and fifth almost equal in length. Thorax: pronotum seen from above paler than anterior part of head capsule; its periphery darker than central area. Coxae and femora yellow; tibiae pale yellow. Anterior margin of pronotum weakly indented in the middle, while posterior margin roundly convex. Abdomen: tergites yellowish to pale brown.
Soldiers (n = 10; (size range) in mm): head length including nasus (HLN) (1.55–1.65); head length measured to base of mandible (HL) (1.05–1.13); nasus length (NL) (0.50–0.60); nasus index = NL/HL (0.47–0.53); maximum head width at posterior part (HWP) (0.95–0.10); maximum height of head excluding postmentum (HH) (0.60–0.65); pronotum length (PL) (0.22-0.25); pronotum width (PW) (0.52–0.55).
Workers. Antenna: whitish yellow to yellow; 15 articles; second clearly longer than third; third the shortest; fourth and fifth almost equal in length. Left mandible: apical and first marginal teeth almost equal in length; third marginal moderately protruding from cutting edge; fourth almost completely hidden behind molar prominence. Right mandible: posterior edge of second marginal tooth nearly straight; inner layer of molar not developed; notch at proximal end of molar plate weakly developed.
Geographical distribution
Sumatra and Borneo.
