Comment

See account by Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 307–309. Ruiz, Cei, and Beçak, 1982, Cytogenet. Cell Genet., 33: 303–311, reported on interpopulational chromosomal evolution. Crespo and Cei, 1983, Arq. Mus. Bocage, Ser. B, 2: 47–55, reported significant genetic distance among two populations of this species (not including the one subsequently named as Odontophrynus barrioi). Peiretti, Basso, and Rosset, 2002, Herpetol. Rev., 33: 221, provided a range extension and commented on the distribution. Pereyra, Martí, Lescano, Rosset, and Baldo, 2009, Amphibia-Reptilia, 30: 571–575, reported a natural hybrid with Odonophrynus cordobae in central Argentina. Morphological differences between nominal Odontophryns barrioi and Odontophrynus occidentalis reported by Crespo and Cei, 1983, Arq. Mus. Bocage, Ser. B, 2: 47-55. Rosset, Ferraro, Alcalde, and Basso, 2007, S. Am. J. Herpetol., 2: 97–106, provided life-history and morphology as well as new records for nominal Odontophrynus barrioi. González, Galvani, Sanabria, Barrasso, Alcalde, and Quiroga, 2014, Acta Herpetol., Firenze, 9: 15–23, reported on larval morphology. Second record of nominal Odontophrynus achalensis by Ávila and Priotto, 1995, Herpetol. Rev., 26: 105. See photograph, map, description of geographic range and habitat, and conservation status of nominal Odontophrynus achalensis in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 402. Martino, Dehling, and Sinsch, 2019, PeerJ, 7(e6480): 1–32, reported on the systematics of this species and revised the synonymy.
