“…Currently, Ameivula has thirteen recognized species (table 1) distributed throughout the CisAndean open-areas south of the Amazon River (Arias et al, 2011b;Harvey et al, 2012;Silva and Ávila-Pires, 2013). These species generally occur in open habitats with sandy soils and high temperature, in very distinct landscape physiognomies, such as the Caatinga (Vanzolini, 1974;Vanzolini et al, 1980;Vitt, 1983Vitt, , 1995Sales et al, 2012), Cerrado (Vitt, 1991), "campos rupestres" Arias et al, 2014), Restingas (Dias and Rocha, 2004;Dias and Rocha, 2007;Santana et al, 2010;, and the Bolivian, Paraguayan and Argentinian Chaco (Williams and Tedesco, 1985;Cei, 1993;Dirksen and De la Riva, 1999;Cabrera, 2012).…”
