【 摘 要 】

Over the last decades, Neotropical region has been subdivided into smaller units (areas of endemism), yet these subdivisions were not necessarily based on an evolutionary perspective. Consequently, these areas of endemism may be biogeographic units that do not actually represent natural historical units. Here, the distributional patterns of the genus Polietina Schnabl & Dziedzicki, 1911 (Diptera, Muscidae; including 15 species) are analysed by applying panbiogeographic tools to recognise and propose primary homologous areas within the Neotropical region. The analysis and discussion of the results obtained here will be reconciled to the information provided by the phylogenetic hypothesis available for the genus.
