Costa Rica, Panama. Costa Rica: rainforest habitats of mid-elevation Atlantic slope, and Osa Peninsula.
This species inhabits rainforest habitats. I have observed diurnal foragers on low vegetation, and I have seen three nests. All three have been from live stems of understory or forest edge plants. One nest was in two internodes of a 3m tall Cecropia sapling. The nest contained workers, soldiers, and brood, but no queen, which suggests the species may be polydomous. Another nest was in internodes of a Cecropia insignis sapling. A third nest was in the main stem of an understory tree sapling. The sapling was leaning across a rainforest trail, and we cut it with a machete to pass by. The stem was 3-4cm in diameter, and ant workers poured out when we made the cut. Further dissection revealed a nest in a clean but irregular chamber, more than a meter long, in the first two meters of the sapling trunk. Gary Hartshorn tentatively identified the sapling as Talisia in the Sapindaceae.
