MURILLO PEIXOTO-COUTO, Rodney; CORREA-BRANCO, Anderson  e  CABRERA-MIGUEL, Maiara. First record of Myocastor coypus (Molina 1782) (Mammalia, Rodentia) for the state of Mato Grosso do Sul, Brazil, and its distribution in southern South America. Actu Biol [online]. 2022, vol.44, n.116, e4.  Epub 25-Maio-2022. ISSN 0304-3584.  https://doi.org/10.17533/udea.acbi.v44n116a04.

This study presents the first record of Myocastor coypus in the state of Mato Grosso do Sul, in addition to detailing its distribution within southern South America, highlighting where it is considered native or exotic in Brazil. On April 23, 2018, at approximately 18:00, an adult specimen with a 40 cm BL (body length) was registered after being run over on a side road near wetlands and a dam in a rural area in the municipality of Bataguassu, eastern state of Mato Grosso do Sul. It is not possible to state the origin of the M. coypus reported in the present study; whether it was introduced or dispersed naturally through the flooded areas of the Paraná River, since the species has records on the border of the states of Mato Grosso do Sul and Paraná.
