Phyllonycteris poeyi Gundlach, 1861, a medium-sized bat, is a phyllostomid commonly called the Cuban flower bat or Poey's flower bat. Phyllonycteris is endemic to the Greater Antilles and P. poeyi is endemic to Cuba and Hispaniola. P. poeyi is characterized by a rudimentary nose leaf, median groove on lower lip ridged with papillae, and ears that are moderately large and separate. P. poeyi shows marked sexual dimorphism in size, with males being larger than females in some cranial and body dimensions. It is a gregarious and obligate cave dweller that usually inhabits the innermost parts of blind galleries. P. poeyi has been captured in evergreen forest, secondary forest, and ravines. P. poeyi is listed as Least Concern by the International Union for Conservation of Nature and Natural Resources.
