Open symbols represent type localities. Question marks: doubtful records of X. scalaris given by Boulenger (1896) and Peters and Orejas-Miranda (1970b) in Bolivia, and probable occurrence of X. werdingorum in the Pantanal of Brazil (see text for details). Additional distribution data taken from Amaral (1923, 1926), Bernarde and Abe (2006), Cadle et al. (2003), Cunha et al. (1985), Harvey et al. (1998), Jensen (1901), Lehr (2002), Loebmann (2009), Pérez-Santos and Moreno (1988, 1991), Schenkel (1902), Strüssman and Sazima (1993), and Wucherer (1862).
