About the Thumbless Bat

The thumbless bat (Furipterus horrens) is a species of insectivorous bat in the family Furipteridae, in the monotypic genus Furipterus. They have a small thumb which is included in the membrane of the wing, causing the 'thumbless' appearance.

The first description of the species was proposed by Frédéric Cuvier in 1828, separating the taxon to a new genus Furia. The taxon was reassigned to Furipterus in 1839 by Charles Bonaparte.

The thumbless bat is found in Central and South America. Its range includes Costa Rica, Panama, southern Brazil and Bolivia. as well as Venezuela, Colombia, Ecuador, Suriname, French Guiana, Guyana, Panama, Trinidad, and Peru.
