Soldier

(Figs 2-4, 7, 8, 10-12, 15, 16). Bimodal continuum in size. Major soldier (Figs 2-4, 7, 8). Head capsule sepia brown to blackish, in dorsal view somewhat triangular, very weakly constricted behind antennal sockets, with posterior margin roundly convex; dorsal outline (including nasus) in lateral view moderately concave; rostrum feebly bicolored, with apical 2/3 lighter and basal 1/3 darker. Mandible with short to long apical processes in dorsal view. Antenna with 14 segments, much paler than head capsule; 1st antennal segment darker than the following segments, which are uniformly colored; 3rd segment 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 paler than head capsule; anterior margin nearly straight; posterior margin weakly indented in the middle. Coxae pale brown to brown; femora pale brown to yellow; tibiae pale yellow. Abdominal tergites pale brown to dark sepia brown. Measurements and index (20 major soldiers from 10 colonies): HLN 2.30-2.71 mm; HL 1.57-1.62 mm; NL 0.72-0.77 mm; NL/HL 0.47-0.51; HWA 0.81-0.98 mm; HWP 1.87-1.92 mm; HH 1.22-1.32 mm; PL 0.37-0.40 mm; PW 0.75-0.78 mm.

Worker

(Figs 5, 6, 9, 13, 14, 17). Monomorphic but showing size variation. Worker (large-sized) (Figs 5, 6, 9). Blackish brown to blackish. Left mandible with apical tooth shorter than 1st marginal tooth; 3rd marginal moderately protruding from cutting edge; 4th completely hidden, scarcely visible behind molar prominence. Right mandible with posterior edge of 2nd marginal tooth nearly straight or weakly concave; the inner layer of molar plate very moderately convex; notch moderately developed. Antenna with 15 segments, whitish yellow; 1st and 2nd segments darker than the following segments; 3rd clearly longer than 4th; 4th longer than 5th, 6 th– 15th gradually shortening toward the apex.
