Native to Central and South America

This genus and its member species are rather robust and are characterized by the presence of relatively long and narrow wings. Their huge wings allow them to fly at high speeds and altitudes of over 3km (10,000 ft).

These species generally roost inside hollow trunks or dead trees and are more or less nocturnal. Data regarding the conservation status of this genus is relatively scarce, but leading experts think some member species might already be threatened due to the rapid deforestation while others might still exist in strong numbers.
