Habitat/Ecology. This species was found in a broad range of habitats spanning across different levels of the disturbance spectrum, including primary and mature secondary forests, young secondary forest fragments in semi-urban settings, mangrove back forests, scrub and open grasslands. Sometimes, the ants were even observed foraging on impervious surfaces in man-made infrastructure. Nests were found in rotting wood, also in soil at bases of large trees.
