Habitat/Ecology. This species is associated mostly with primary or old/mature secondary forests, sometimes also in well-developed young secondary forest fragments in Singapore. A single alate was collected from swamp forest in a malaise trap sample. These are very large ground-foraging ants that form relatively small colonies.
