Modern Gracilidris is known from Brazil, Paraguay, and Argentina, where it has been collected in a variety of open habitats such as Campo Cerrado and Chaco. These ants have been encountered only a few times, so the actual range may be greater than the known distribution. The figure at right shows the locations where G. pombero is known to occur in South America.
The extinct species G. humilioides has been collected on the Caribbean island of Hispaniola in fossilized amber (Wilson 1985).
