Eguchi et al. (2009) - K. Eguchi and V.T. Bui collected workers of Anillomyrma decamera in a well-developed dry forest in the southern coastal part of Vietnam, by underground bait-trapping; baits (pork sausage) were buried in sandy soil. On the other hand, J. Caceres, a colleague of D.M. General, collected A. decamera in abandoned agricultural land that had isolated stands of abaca plants (Musaceae: Musa textilis NÉE) and jackfruit trees (Moraceae: Artocarpus heterophyllus LAM.), and was overgrown with tall grasses, upright and creeping bamboos and tree ferns. Ant samples were obtained by sifting a soil core sample taken from a deep sandy loam of volcanic origin. Bolton (1987) collected A. tridens on sandy ground in a lowland rain forest. These facts suggest that the distribution of this species may be affected by soil type. Emery (1901) mentioned that the type material of A. decamera was collected from termite nest(s). Anillomyrma may actively hunt soil invertebrates, including termites, using its well-developed sting to envenomate prey, and it may also scavenge animal matter under the ground. Bolton (1987) tentatively suggested that A. tridens is nomadic. These scattered observations may help us to develop collecting and observing methods for these mysterious ant species.
The eyes are absent. The body is small and thin (less than 2.8 mm long) and uniform pale yellow in color. Similar to Solenopsis but differs in having a three-segmented rather than two-segmented antennal club and in the complete lack of eyes. Solenopsis have small eyes. Also similar to Leptanilla because of their elongate body and lack of eyes. Differ by the presence of frontal lobes that partially cover the antennal sockets. Similar to Dolopomyrmex (United States) but Anillomyrma lacks the median clypeal seta. (Shattuck 1999 and Eguchi et al. 2009)
Workers of the genus are recognised by the following features: 10-segmented antennae; postpetiole attached to top of anterior face of first gastral segment (Bolton, 1994; Eguchi et al., 2010; Hosoishi et al., 2015).
