Habitat/Ecology. This species is associated with primary or secondary forests in Singapore, including young secondary forests. The ants have been found mostly in or under bark of large dead trees in old secondary forest. In one instance, nestmates were found in the trunk cavity of a very large, relatively fresh-fallen tree. Though often reported elsewhere to be associated with termites, no such associations were observed or recorded for local occurrences of this species. The ants have also been found boring in rotten timber under bark of standing dead trees ca. 50 feet above ground, in deep bark scrapings of trees, and under frais-filled bark.
