Costa Rica, Panama and Guyana. Costa Rica: Pacific lowlands (Corcovado and Santa Rosa national parks).
Basal tooth of mandible greatly enlarged, roughly rectangular in shape; antennae with 8 segments, with apical segment greatly enlarged, twice as wide as other segments and almost as long as all other funicular segments combined.
This species occurs in moist forest habitats of Costa Rica's Pacific lowlands. Longino found two colonies under stones in the "bosque humedo" of Santa Rosa National Park, on 15 July 1985. One nest contained alate queens and males. Workers were also collected in a Winkler sample of sifted leaf litter from Sirena in Corcovado National Park.
