See discussion by Hoogmoed, 1986, in Rocek (ed.), Studies in Herpetol.: 147-150, and Hoogmoed, 1990, in Peters and Hutterer (eds.), Vert. Tropics: 117-120, who noted that this species was referred to erroneously as Bufo dapsilis by Zimmerman and Bogart, 1988, J. Herpetol., 22: 97-108, and who removed it from the synonymy of Rhinella margaritifera (referred to as Bufo typhonius), where it had been placed by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 315. The diagnostic differences between this form and geographically proximate members of Rhinella are not well documented. See comment under Rhinella margaritifera.
