Distribution Notes:

Costa Rica to Argentina. Costa Rica: seasonally dry areas of northwestern lowlands.


Natural History:

In Costa Rica, this species appears to be an inhabitant of open, disturbed areas in the seasonally dry areas of northwestern Costa Rica. I know it from two collections of foragers, one from a city park in the middle of Liberia, and one from sweepnetting scrubby roadside vegetation along the road to Monteverde, near the PanAmerican highway. I have never seen a nest.
