Abstract: The Cerrado and the Caatinga have few formally protected areas and encompass a high diversity of amphibians, which is still relatively unknown. In this study we present the list of amphibian species endemic to the Cerrado or Caatinga and their geographic range, highlighting current conservation status. We obtained the species list from the compilation of scientific publications (up to July 2022). We obtained the occurrence records from the databases SpeciesLink, GBIF, Portal da Biodiversidade and literature. We classified the species in the categories of threat according to the Brazilian list of threatened species and the global list of threatened species. We compiled 2,659 occurrences of amphibians, 1,335 from the SpeciesLink platform, 414 from GBIF, 371 from the Biodiversity Portal and 539 obtained from the literature. We recorded 100 endemic species, 82 from the Cerrado and 18 from the Caatinga. The Cerrado has three species Vulnerable (VU) (Boana buriti, Bokermannohyla napolii and Scinax pinimus), one Critically Endangered (CR) (Proceratophrys moratoi), 14 species Data Deficient (DD), 46 in the Least Concern (LC) category and 18 Not Evaluated (NE). The Caatinga has three species CR (Adelophryne maranguapensis, Proceratophrys ararype, Rhinella casconi), three DD, five LC and seven NE. Threatened, DD and NE species have few records within the protected areas of Cerrado and Caatinga. We consider that the Cerrado and Caatinga present a rich diversity of endemic amphibians, which have a geographic range relatively reduced, especially the threatened ones, DD and NE. Distribution and taxonomy data are essential, because the lack can hinder the assessment of conservation status, since threatened species, DD, NE, including LC, may be undervalued and at risk.
