Range
Argentina, southern Brazil, Guianas, Costa Rica.
Identification
The only known Costa Rican member of the genus.
Natural History
In Costa Rica I know this species almost exclusively from Winkler samples of sifted leaf litter from the forest floor. I have records of workers from Carara Biological Reserve in the southern Pacific lowlands, Maritza Biological Station in Guanacaste, and La Selva Biological Station and CATIE on the Atlantic slope. An enigmatic collection is two alate queens collected by Angel Solis, the Coleoptera curator at INBio. He was on a lunch break on the grounds of the INBio collection facility in Santo Domingo de Heredia and he observed a nuptial flight. He collected two queens and gave them to me. Although they did not have associated workers, I identified the queens as Carebarella and am assuming they are the queens of C. bicolor.
