Anillomyrma tridens Bolton View in CoL HNS , 1987 (Figs. 11 - 15)
Anillomyrma tridens Bolton HNS , 1987: 274-275, 440. Holotype worker: East Malaysia: Sarawak , 4th Division , Gunong Mulu Nat. Park , RGS Exped., Long Pala , lowland rain forest in sandy soil, leg. B. Bolton, 11.X.1977 ( BMNH) ; paratypes: workers with same data as holotype ( BMNH, MCZ, MHN, NMB). Fifteen paratypes (personally donated to ACEG by B. Bolton) and 9 paratypes ( MCZC) examined .
Worker diagnosis. 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 three large sharp teeth. Apical and preapical teeth close together, separated by a diastema from 3rd tooth; 3rd much larger than 2nd; 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. Dorsum and posterior slope of propodeum in lateral view forming rounded outline. Petiolar peduncle in lateral view relatively slender (as in Fig. 11).
Worker measurements and indices. Holotype and 10 paratype workers (cited from Bolton 1987): CI 88 - 90, HL 0.37 - 0.39, HW 0.33 - 0.36, PW 0.24 - 0.25, SI 57 - 60, SL 0.21 - 0.23, WL 0.35 - 0.39.
Distribution. Malaysia: Sarawak.
Remarks. Anillomyrma tridens HNS is morphologically very similar to A. decamera HNS . The only conspicuous morphological characters separating the two species are as follows: head slightly longer than broad, masticatory margin of mandible of A. tridens HNS having 3 distinct teeth as mentioned by Bolton (1987) (but very small 4th tooth rarely present) (Fig. 13); the 3rd tooth of A. tridens HNS much larger than 2nd (Fig. 13); posterior slope of propodeum in lateral view expanding posterodorsad more strongly in A. tridens HNS (Fig. 11) than in A. decamera HNS (Fig. 1); petiolar peduncle in lateral view more slender in A. tridens HNS (Fig. 11) than in A. decamera HNS (Fig. 1).
