Collection records show this species inhabits a range of moist forest habitats and, with most collections having come from litter sampling, is apparently a soil or litter dwelling ant.


Weber (1942) - The thorax of this ant is like that of many Euponera species yet it has but one well-developed tibial spur on the middle and hind legs.
