Costa Rica to Bolivia. Costa Rica: known from both wet and dry forest, in Atlantic and northern Pacific lowlands (Santa Rosa, road from PanAmerican Highway to Monteverde, Tortuguero, La Selva Biological Station, 500m in Braulio Carrillo National Park south of La Selva).


Natural History:

This large arboreal ant prefers open sunny areas. I have collected workers in Santa Rosa National Park, in scrubby vegetation along the road to Monteverde, in open pasture areas around Rara Avis, and in isolated trees in young secondgrowth areas of La Selva Biological Station. I observed one nest in a recently felled Hieronyma oblonga tree. The tree was in a pasture in an area of active clearing of rainforest, at 500m elevation just south of La Selva. A small nest entrance hole, little larger than a worker, lead to a large cavity in a knot, where there were abundant workers.

This species is similar to villosa in morphology and size. It is generally sympatric with villosa, but villosa is more abundant and has a broader habitat range, occurring abundantly in dry forest, in disturbed habitats, and in mature rainforest.
