Habitat/Ecology. Workers of this species were found together with Tetramorium obtusidens Viehmeyer, 1916 and Technomyrmex albipes (Smith, 1861) in the same withered branch of a roadside tree; workers have also been collected from Nepenthes pitcher cups. The species appears mostly associated with old/ mature secondary forests in Singapore, including swamp forest.
