Habitat/Ecology. This species is associated mostly with primary and old/mature secondary forests in Singapore, but has sometimes also been found in more degraded or disturbed young secondary forests, including mangrove back forest. Individual foragers have occasionally been collected from under bushes beachside, presumably originating from adjacent coastal beach forest. These ants were often found foraging in and around leaf litter.

Remarks. Type locality in Singapore.
