Inclusão, exclusão e reinclusão: Chironius brazili (Serpentes, Colubridae) no Rio Grande do Sul, sul do Brasil

Abstract

Although Chironius brazili Hamdan and Fernandes, 2015 was recently described, its occurrence in Rio Grande do Sul, southern Brazil, has been discussed for at least three decades. In this work, we evaluate the occurrence of C. brazili in Rio Grande do Sul, presenting three new records, a distribution extension and comments in its available literature records. In the Pampa biome, all records are near areas of Atlantic Forest, in grassywoody steppes with gallery forest, in western Rio Grande do Sul. Our records suggest that C. brazili might occur in the Central Depression of Rio Grande do Sul, Uruguay and adjacent areas to the Western portion of Rio Grande do Sul.
