Localidades-tipo dos anfíbios e répteis de Minas Gerais

Abstract

The precise definition of type localities is essential for taxonomic, biogeographic, and conservation studies, as it enables the identification of genetically unsampled areas and potential extinctions. However, many historical descriptions are imprecise, complicating taxonomic revisions and the application of molecular techniques. This study reviewed the type localities and the availability of genetic sequences for amphibians and reptiles associated with the state of Minas Gerais, Brazil. A total of 181 species with type localities in the state were identified, of which 158 are valid and 58 are synonyms. Most type specimens are housed in Brazilian collections, although some have been lost. Only seven names have sequenced type specimens; 71 have at least one sequenced topotype, and seven have at least one specimen sequenced from a site near the type locality. Ninety-five names remain without genetic sequencing of type specimens or topotypes. The data highlight the need to search for topotypes for nearly a hundred species and emphasize the importance of preserving zoological collections to maintain knowledge of biodiversity.
