Comment

Of uncertain validity according to Cei, 1972, in Blair (ed.), Evol. Genus Bufo: 89. Recognized as a poorly known species by Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 203-204, and belonging to the Bufo veraguensis (formerly Bufo ockendeni) group. Rejected as a member of the Bufo veraguensis group by Duellman and Schulte, 1992, Copeia, 1992: 162-172. See account by Carrizo, 1992, Cuad. Herpetol., 7: 14-23. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 58, and Köhler, 2000, Bonn. Zool. Monogr., 48: 69, thought this species possibly to occur in Bolivia. Not recollected since the types according to Lavilla and Cei, 2001, Monogr. Mus. Reg. Sci. Nat. Torino, 28: 25. Lavilla, Barrionuevo, and Baldo, 2002, Cuad. Herpetol., 16: 100–101, implied that this may be a synonym of Rhinella spinulosus
