Distribution Notes:

Costa Rica: throughout country in mid-elevation sites (above 500m).


Natural History:

This species is relatively common in mid-elevation sites, in mature forest habitats. I have found it at the 1070m and 1500m sites on the Barva Transect in Braulio Carrillo National Park, at Refugio Eladio in the Penas Blancas Valley east of Monteverde, at Estacion Cacao in the Guanacaste Conservation Area, and in the small cloud forest on the highest ridges of the Osa Peninsula in Corcovado National Park.

The quantitative sampling on the Barva Transect by the ALAS project yielded workers in Winkler samples, flight intercept traps, Malaise traps, and sweep net samples. At Penas Blancas I have found foragers on the trails. At Cacao I excavated an entire nest. It was in a clay bank along the trail, at the edge of the mature forest below the station building. There were two chambers, an upper one relatively near the surface, and a lower one about 20cm deep. The upper chamber contained only small fungus masses; the lower chamber contained the colony queen and a much larger fungus mass. I scooped the contents into a plastic bag, and a few minutes later observed an adult diapriid male in the bag (I gave the specimen to Lubomir Masner that evening).
