Tonatia

Although keys to the species of Tonatia provided by Genoways and Williams (1984) and Medellín and Arita (1989) are useful tools for identification, neither is complete; the former covers only the species known from Surinam, and the latter was published before T. bidens and T. saurophila were recognized as distinct species (see below). All of the five species of Tonatia known from the Guiana subregion of Amazonia are sympatric (and apparently syntopic) at Paracou.
