The prehensile-tailed hutia (''Mysateles prehensilis'') is a small, furry, rat-like mammal found only in forests on Cuba. It is the only member of the genus ''Mysateles''. It climbs and lives in trees where it eats only leaves, and it is threatened by habitat loss. The prehensile-tailed hutia is a member of the hutia subfamily (Capromyinae), a group of rodents native to the Caribbean that are mostly endangered or extinct. There is one subspecies, ''M. prehensilis gundlachi'' (also known as Chapman's prehensile-tailed hutia or Gundlach's hutia).

Taxonomy

The genus name ''Mysateles'' derives from the two ancient greek words (), meaning "mouse, rat", and (), meaning "incomplete, imperfect". Within Capromyidae, the closest relative of ''Mysateles'' is the genus ''Mesocapromys''. Both genera are the sister group to ''Capromys'', and then ''Geocapromys'' is a more distant genus. In turn, these four genera belong to the tribe Capromyini, and are the sister group to ''Plagiodontia''. Several other hutia species such as Garrido's hutia (''Capromys garridoi'') and the

(''Mesocapromys melanurus'') were formerly classified in ''Mysateles'', but phylogenetic evidence found them to belong in different genera, leaving only ''M. prehensilis'' in ''Mysateles''. A subspecies, ''Mysateles prehensilis gundlachi'' (also known as Chapman's prehensile-tailed hutia or Gundlach's hutia) was previously considered a separate species (''Mysateles gundlachi''). The Isla De La Juventud tree hutia (''M. p. meridionalis'') was also previously considered a separate species, but was found to be a subspecies by phylogenetic studies.
