Southern Mexico to Colombia (Brown 1976). Costa Rica: common in uplands of Cordillera de Tilaran and Cordillera Volcanica Central; the common species in Monteverde; less common to sea level on Atlantic slope (La Selva) and 500m on Pacific slope (Carara).
In Monteverde the diurnal foragers are common, and on warm days alate queens commonly fly into buildings. Nests are in rotten wood on the ground. Workers have been observed harvesting Calathea seeds. The species is rare at La Selva.
