Worker diagnosis. (Also see "Worker description" under the genus description). Body sculpture absent except for hair-pits, which are most conspicuous on head and promesonotum ; dorsum of head, promesonotum and gaster relatively densely covered with short suberect to decumbent hairs. Head in full-face view roughly rectangular, longer than broad; mandible with 4 distinct teeth of which basal one is smaller than the others and 3rd almost as large as 2nd (preapical tooth); antennal scape short, reaching only 7 / 10

- 3 / 4 of distance from anterior margin of clypeus to posterior margin of head; apical antennal segment more than 3 times as long as preapical segment. Dorsum of mesosoma in lateral view flat; posterior slope of propodeum in lateral view hardly expanding posterodorsad. Petiolar peduncle in lateral view gradually thickened toward node.

Worker measurements and indices. Type material (3 syntype workers of " Anillomyrma decamera ssp. continentisHNS ", but 2 measured for PW and WL): CI 79 - 82, HL 0.34

- 0.35 mm, HW 0.27 - 0.29 mm, PW 0.19 mm, SI 66 - 67, SL 0.18 - 0.19 mm, WL 0.46 - 0.48 mm; Vietnamese material(5 workers from BTN 16xii 08-18): CI 80 - 83, HL 0.37

- 0.38 mm, HW 0.30 - 0.32 mm, PW 0.21 - 0.23 mm, SI 67

- 72, SL 0.21 - 0.22 mm, WL 0.46 - 0.48 mm; Philippine material (3 workers from Isarog): CI 83 - 87, HL 0.33 - 0.37 mm, HW 0.28 - 0.32 mm, PW 0.19 - 0.22 mm, SI 61

- 65, SL 0.18 - 0.19 mm, WL 0.43 - 0.47 mm; Chinese material(3 workers from Jungshan, but 2 measured for WL): CI 85 - 86, HL 0.34 - 0.35 mm, HW 0.29 - 0.30 mm, PW 0.20 - 0.22 mm, SI 66 - 67, SL 0.20 mm, WL 0.47 mm.

Distribution. India: Bihar (Bolton 1987). Sri Lanka: Anuradhapura. Vietnam: Ba Ria - Vung Tau; "Van Phu". China: "Jungshan". Philippines: Luzon.

Remarks. CI is greater in the material from Isarog and Jungshan than in the material from Vietnam; SI is smaller in the material from Isarog than in the material from Vietnam and Jungshan.
