Distribution Notes:

Costa Rica: Atlantic slope, from sea level to 900m elevation.


Natural History:

This species occurs in Atlantic slope wet forest. At Tortuguero I found a colony inside a nasutiform termite nest. Workers were scattered throughout, but separate from the areas inhabited by termites. Brood occurred in spatially separated small batches of 10-20 larvae. In the Pe–as Blancas Valley east of Monteverde, at 800m and 900m elevation, I twice observed nocturnal columns on the ground. During the ALAS expeditions on the Barva Transect, workers were obtained in a Winkler sample from the 500m site and a sweepnet sample from the 300m site.
