Wiedomys pyrrhorhinos is endemic to the Caatinga, and has been recorded in the Brazilian states of Alagoas, Bahia, Minas Gerais, Paraiba , and Pernambuco ( Maia and Langguth 1987 , Pereira and Geise 2009 , Souza et al. 2011a , Bonvicino 2015 , Nogueira et al. 2015 ). Bonvicino (2015) indicated that the species is also present in the state of Sergipe, but this assertion is based on an abstract presented at the XXIV Jornadas Argentinas de Mastozoologia .
