Comment

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 removed this species from the synonymy of Bufo margaritifer (as Bufo typhonius), where it had been placed by Duméril and Bibron, 1841, Erp. Gen., 6: 719, and Günther, 1859 "1858", Cat. Batr. Sal. Coll. Brit. Mus.: 69; Steindachner, 1867, Reise Österreichischen Fregatte Novara, Zool., Amph.: 47; and Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 317. The diagnostic differences between this form and geographically proximate members of the taxon are not well documented, nor are the species' distributions. See comment under Rhinella margaritifera. See comment under Rhinella alata. Gorzula and Señaris, 1999 "1998", Scient. Guaianae, 8: 19, suggested that Rhinella margaritifera (as Bufo margaritifer) is found in southern Venezuela and Rhinella alata (as Bufo alatus) is found north of the Orinoco. César L. Barrio-Amorós, personal commun., notes that no specifically identified vouchers exist for Venezuela. See comments under Rhinella alata. In the Rhinella margaritifera clade, Rhinella margaritifera group of Pereyra, Blotto, Baldo, Chaparro, Ron, Elias-Costa, Iglesias, Venegas, Thomé, Ospina-Sarria, Maciel, Rada, Kolenc, Borteiro, Rivera-Correa, Rojas-Runjaic, Moravec, De la Riva, Wheeler, Castroviejo-Fisher, Grant, Haddad, and Faivovich, 2021, Bull. Am. Mus. Nat. Hist., 447: 1–156. Fouquet, Ferrão, Rodrigues, Werneck, Prates, Moraes, Hrbek, Chaparro, Lima, Perez, Pansonato, Carvalho, Almeida, Gordo, Farias, Milto, Roberto, Rojas-Zamora, Ron, Guerra Batista, Recoder, Camacho, Mamani, Rainha, and Ávila, 2024, Syst. Biodiversity, 22 (1, 2291086): Appendix 2, discussed systematics and range and suggested that the nominal species is composed of a number of independent lineages all waiting on additional evidence for sufficient understanding.
