Material examined.

SYK1998 & 1999-L-1098, 2001, 3011: soldiers and workers from the undisturbed forest, 1100-1400 m altitude, Kemiri Mountain, Southeast Aceh, Aceh, Sumatra.

Soldier

(Figs 18-20, 23, 24, 26-28, 31, 32). Bimodal continuum in size. Major soldier (Figs 18-20, 23, 24). Head capsule pale to dark brown, in dorsal view somewhat triangular, very weakly constricted behind antennal sockets, with posterior margin roundly convex; dorsal outline (including nasus) in profile moderately concave; rostrum feebly bicolored, with apical 2/3 darker and basal 1/3 paler. Mandible with short to long apical processes. Antenna with 14 segments, much paler than head capsule; 1st and 2nd antennal segments darker than the following segments, which are uniformly colored; 3rd approximately 1.5 times as long as 4th; 5th slightly shorter than 4th; 6 th– 14th gradually shortening toward the apex. Pronotum in dorsal view as pale as or paler than head capsule; anterior margin indented in the middle; posterior margin weakly indented in the middle. Coxae and femora yellowish to pale brown; tibiae pale yellow to yellow. Abdominal tergites brown to dark sepia brown. Measurements and index (20 major soldiers from 10 colonies): HLN 2.22-2.43 mm; HL 1.62-1.68 mm; NL 1.02-1.12 mm; NL/HL 0.66-0.73; HWA 0.86-0.90 mm; HWP 1.63-1.71 mm; HH 0.98-1.04 mm; PL 0.40-0.44 mm; PW 0.77-0.82 mm.

Worker

(Figs 21, 22, 25, 29, 30, 33). Monomorphic but showing size variation. Worker (large-sized) (Figs 21, 22, 25). Body pale brown to brown. Left mandible with apical tooth shorter than 1st marginal tooth; 3rd marginal weakly protruding from cutting edge; 4th not completely hidden behind molar prominence. Right mandible with posterior edge of 2nd marginal tooth nearly straight; the inner layer of the molar plate very weakly concave; notch moderately to strongly developed. Antenna with 15 segments, with 1st and 2nd segments slightly darker than the following segments; 3rd clearly longer than 4th; 4 th– 6th nearly equal in length; 7 th– 15th gradually shortening toward the apex.

Distribution.
