The gray short-tailed bat is a small bat recorded in the dry-forest region of northwestern Nicaragua. A local field survey found both males and females in March.
The Cosigüina Peninsula paper describes this species as smaller than its congener Carollia perspicillata. Mean body mass of the collected specimens was 14.4 g for males and 13.2 g for females.
The Nicaraguan survey collected 11 bats from 2 to 6 March. One female was carrying a young bat when caught; a different female gave birth to one young in a holding bag after capture.
