Distribution extension in Colombia and new records for Brazil of Micrurus isozonus (Cope, 1860) (Squamata, Serpentes, Elapidae)

Abstract

Micrurus isozonus is a triadal coralsnake occurring in northern Venezuela, eastern Colombia, southern Guyana, and in the extreme northern Brazil. In this paper we firstly publish vouchers to Brazil, and report additional records from three localities in the mountainous region of Taião and Apiaú, state of Roraima. We also extend its known range to the Trans-Andean region in the Atlantic coast of northern South America, municipality of Cartagena at the Caribbean coast of Colombia. Additionally, we present meristic and morphometric data, including the species sintypes.
