Crossodactylus bokermanni is a spinythumb frog known only from the type locality and categorized as Endangered or Vulnerable in different red lists. The examination of many unidentified specimens collected in the range of the Serra do Espinhaço, State of Minas Gerais, Brazil, revealed that C. bokermanni has a wider distributional range than previously reported. Nontopotypic specimens could not be referred to C. bokermanni earlier because of the confused taxonomy of the genus. A detailed comparative diagnosis is presented, and morphological and acoustical variations are characterized to accurately determine the species limits of C. bokermanni. Previous studies presenting evidence for the decline of the topotypic populations of C. bokermanni are not supported by the available literature, museum collections, and recently collected field data. The conservation status of this species needs to be revised based on the new information regarding the geographic distribution of the species.
