See accounts by Rivero, 1961, Bull. Mus. Comp. Zool., 126: 83; and Cochran and Goin, 1970, Bull. U.S. Natl. Mus., 288: 364–366. Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 41, commented on the range in Venezuela. Lynch, 1982, Syst. Zool., 31: 166–179, reported the Venezuelan Amazonian population which had previously been confused with Ceratophrys cornutaFaivovich, Nicoli, Blotto, Pereyra, Baldo, Barrionuevo, Fabrezi, Wild, and Haddad, 2014, S. Am. J. Herpetol., 9: 207–227, suggested that this species is the sister taxon of Ceratophrys cornuta. Barrio-Amorós, 2004, Rev. Ecol. Lat. Am., 9: 19, 29, considered the population at Puerto Ayacucho, Venezuela. to represent Ceratophrys calcarata, rather than Ceratophrys cornuta as previously identified. Acosta-Galvis, 2012, Biota Colomb., 13: 213–231, reported the species in the Departamento Sucre, northern Colombia, and briefly discussed habitat. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 28–30, for comments on range, taxonomy, and literature. Señaris and Rojas-Runjaic, 2020, in Rull and Carnaval (eds.), Neotrop. Divers. Patterns Process.: 571–632, commented on range and conservation status in the Venezuelan Guayana. Santos-Morales and Mendoza-Roldán, 2019, Catal. Anf. Rept.
