Habitat/Ecology. This species is associated with old/mature secondary forests in Singapore. Nests were observed to occur at rather high density (separated only by a few metres from each other) within a limited area of forest, though these could possibly be merely satellite colonies. The ants were usually found nesting in soil-roots-substrate matrices on bark/trunk surfaces near bases of trees.
