'''Carollia''' is a genus of
bats often referred to as the short-tailed fruit bats. Along with the genus ''
Rhinophylla'', ''Carollia'' makes up the subfamily
Carolliinae of family
Phyllostomidae, the leaf-nosed bats. Currently, nine species of ''Carollia'' are recognized, with a number having been described since 2002. Members of this genus are found throughout tropical regions of Central and South America but do not occur on Caribbean islands other than
Trinidad and Tobago. Bats of the genus ''Carollia'' often are among the most abundant mammals in Neotropical ecosystems and play important roles as seed dispersers, particularly of
pioneer plants such as those of the genera ''
Piper'', ''
Cecropia'', ''
Solanum'', and ''
Vismia''.
