Colombian bonneted bat

The Colombian bonneted bat (Eumops trumbulli), also called Trumbull's bonneted bat, is a South American bat found in Bolivia, Brazil, Colombia, French Guiana, Guyana, Peru, Suriname and Venezuela. The British naturalist Oldfield Thomas described it in 1901 as Promops trumbulli and named it for Dr. J. Trumbull, who collected the holotype at Para, Brazil, in May 1898. In 1906 it was moved to the new genus Eumops, where it has stayed. In 1932 it was treated as a subspecies of the western mastiff bat, but in 1977 Eger restored it to full species rank. It is one of the larger members of its genus, with 30 teeth and small, squarish tragi, and Thomas found it similar to the western mastiff bat but with smaller ears, smaller tragi and lighter teeth. The IUCN rates it least concern because of its wide range, presumably large population and the lack of evidence for a rapid decline.
