Habitat/Ecology. This species is associated mainly with disturbed young secondary habitats in semi-urban settings in Singapore including waste woodland forest, and sometimes also scrubland. Colonies have been found in rotting wood and bamboo in a garden.A nest was also found in an electrical circuit box beside a bus stop outside a university campus building.

Remarks. Tetramorium bicarinatum is considered a highly successful and globally widespread tramp species, occurring in almost all tropical and subtropical habitats worldwide. It has been strongly postulated to be native to the Southeast Asian region, and introduced to the rest of the world ( Bolton 1977). Morphologically similar to another pantropical tramp species – T. insolens (also listed here), T. bicarinatum can be distinguished from the latter by its sculptured mandibles, rectangular nodiform petiole with antero- and posterodorsal angles at identical heights, and finally its bicolored body.
