Natural History:

This is an extremely tiny ant. I know the species from two collections:

Costa Rica, Prov. Puntarenas, Osa Peninsula, Ranch Quemado: ex sifted leaf litter from wet forest floor (Winkler sample).

Costa Rica, Prov. Heredia, 17km N Vol. Barba, 800m (Barva Transect): ex sifted leaf litter from wet forest floor (Winkler sample).


Fern‡ndez described this species from one collection from Peru. This species matches the description and keys to C. inca, although it is difficult to distinguish his C. inca and C. paya (a related species from Colombia).
