Polychrus acutirostris is widespread in a large part of the South America diagonal of open formations, in the Caatinga, Cerrado, Pantanal, and Chaco, with pointed records in the Amazonia and Atlantic Forest, occurring in Brazil, Bolivia, Paraguay, and Argentina ( Fig. 13 ). In Brazil it is known from the states of Pará, Tocantins, Rondônia, Mato Grosso, Mato Grosso do Sul, Goiás, Maranhão, Piauí, Ceará, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Minas Gerais, São Paulo, and in the Distrito Federal. In Amazonia it occurs in open vegetation enclaves in southern Rondônia and Pará, along the Tocantins River, in northern Mato Grosso, in Brazil, and in northern Bolivia. Polychrus acutirostris is arboreal and diurnal, inhabits arboreal savannas, where it is found mainly on branches of trees and bushes ( Ávila-Pires 1995; Vitt 1995; Rodrigues 1996; Gainsbury & Colli 2003; Rodrigues 2003).
