“…The genus Mussurana Zaher, Grazziotin, Cadle, Murphy, Moura-Leite & Bonatto, 2009 (Serpentes, Colubridae) comprises three species: Mussurana bicolor (Pe racca, 1904), M. montana (Franco, Marques & Puorto, 1997), and M. quimi (Franco, Marques & Puorto, 1997). These are terrestrial, possibly semifossorial, snakes known to inhabit open savannahs, wetlands, gallery forests, Pantanal, Chiquitano dry forest, and Chaco (Cei 1993;Strussmann and Sazima 1993;Couturier and Faivovich 1996;Franco et al 1997;Morato et al 2003;Álvarez et al 2009;Cabral and Weiler 2014;Cano et al 2015;Cacciali et al 2016;Nogueira et al 2019). Morphologically these species are characterized as being smaller-bodied, having fewer ventral scales, and with unique coloration as compared to species of Boiruna Zaher, 1996, Clelia Fitzinger, 1826, and Pseudoboa Schneider, 1801(Zaher 1996Franco et al 1997;Morato et al 2003;Zaher et al 2009).…”
