This bat was distinguished from the Carollia castanea species complex in a 2006 study. Its original description lists records south of the Amazon in Peru, Bolivia, and Brazil. A separate study at Pozuzo, Peru, found an association between its abundance and forest-edge density.
The original description reports chestnut to pale-brown fur, apparently naked forearms, and a shallow notch in the edge of the tail membrane. These features are shared with the related C. castanea and do not distinguish this species on their own.
In the Yavarí-Ucayali region of northeastern Peru, ground-level nets at Nuevo San Juan captured it in the understory of primary upland forest and in secondary vegetation, as well as in clearings, a swampy mineral lick, a palm swamp, and on a beach. Another bat was captured near El Chino village, at an unrecorded net height.
An extinction-risk assessment has not been added yet.
