Validation of Eleutherodactylus crepitans Bokermann, 1965, notes on the types and type locality of Telatrema heterodactylum Miranda-Ribeiro, 1937, and description of a new species of Eleutherodactylus from Mato Grosso, Brazil (Amphibia: Anura: Leptodactylidae)

Examination of the types of Eleutherodactylus crepitans Bokermann, 1965, indicates that they represent a valid species, which should be removed from the synonymy of Eleutherodactylus fenestratus (Steindachner 1864). Eleutherodactylus crepitans is only known from the type material. Certain features of the types of Telatrema heterodactylum Miranda-Ribeiro, 1937, are described and the type locality clarified. Analysis of the advertisement call and morphology of a series of specimens from Chapada dos Guimaraes indicates that the specimens represent a species distinct from E. fenestratus (Steindachner 1864), for which no name is available. We describe this new species as Eleutherodactylus dundeei. The frog fauna of Chapada dos Guimaraes contains four distinct historical units: cerrado, chaco, Amazonian hylaea, and endemic.
