The nest series from which the holotype was selected was collected from lowland rainforest. The nest was in a trailside woody plant stem whose apex was an old machete cut. The ants inhabited the dead terminus of the branch, just distal to the live portion. The live stem was solid, and the ants were in chambers excavated either by themselves or by a previous stem-boring insect. The entire nest was sampled, and contained 108 workers, one dealate queen, one alate queen, and brood. The other specimens from the type locality were collected from low vegetation. The worker from below Volc‡n Barba was collected from the canopy of primary rainforest, approximately 20m high.Workers from 17km S Puerto Viejo were in the crown of a recent treefall, in primary wet forest.
