Class: Amphibia > Order: Anura > Family: Odontophrynidae > Genus: Odontophrynus > Species: Odontophrynus asper

Hyperoodon asper Philippi, 1902, Supl. Batr. Chil. Descr. Hist. Fis. Polit. Chile: 1. Types: MNHNC or MHNM (2 specimens; museum unclear in text) according to the original publication; not located in MHNM, according to Klappenbach and Langone, 1992, An. Mus. Nac. Hist. Nat. Montevideo, Ser. 2, 8: 200; by implication of Cei, 1958, Invest. Zool. Chilen., 4: 265–288, probably not found in MNHNC. MNHN 9937 designated neotype by Rosset, Baldo, Borteiro, Kolenc, Cazzaniga, and Basso, 2022, Herpetol. Monogr., 36: 87. Type locality: "Montevideo". Neotype from Naranjo Amargo Farm, Rincón del Cerro, Montevideo, Montevideo Department, Uruguay (34°52′37″S, 56°18′20″W)".

Hiperoodon asper — Philippi, 1902, Supl. Batr. Chil. Descr. Hist. Fis. Polit. Chile: 159. Incorrect spelling of generic name.

Ceratophrys argentina Philippi, 1902, Supl. Batr. Chil. Descr. Hist. Fis. Polit. Chile: 72. Holotype: Animal in figure of Pyxycephalus americanus in Bell, 1843, Zool. Voyage Beagle, Part 5: figs. 2, 2a–c; pl. 18, presumably in BMNH. Type locality: Not designated, although Argentina is implied by the species name. Synonymy with Odontophrynus americanus by Klappenbach and Langone, 1992, An. Mus. Nac. Hist. Nat. Montevideo, Ser. 2, 8: 200–201; with Odontophrynus asper by Rosset, Baldo, Borteiro, Kolenc, Cazzaniga, and Basso, 2022, Herpetol. Monogr., 36: 87.

Comment

Hyperoodon asper was placed in tentative synonymy with Odontophrynus americanus by Cei, 1958, Invest. Zool. Chilen., 4: 266 (who provided the long missing original illustration); synonymy with Odontophrynus americanus by Klappenbach, 1968, Invest. Zool. Chilen., 23: 148, and Lynch, 1970, Copeia, 1970: 494–495. Márquez, De la Riva, and Bosch, 1995, J. Zool., London, 237: 313–336, reported on vocalization in Bolivia (nominally as Odontophrynus americanus, but like Odontophrynus asper). Salas, Zavattieri, di Tada, Martino, and Bridarolli, 1998, Cuad. Herpetol., 12: 37–48, discussed the call (likely Odontophrynus asper, but as Odontophrynus americanus). Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 35, provided a brief account and photograph for the Uruguay population (as Odontophrynus americanus, but likely Odontophrynus asper). Eterovick and Sazima, 2004, Anf. Serra do Cipó: 99–100, provided a photograph and brief account (as Odontophrynus americanus). Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 16, briefly discussed the range (as Odontophrynus americanus) in Paraguay. Grenat, Salas, and Martino, 2009, Zootaxa, 2049: 67–68, documented that erythrocyte volume differs between this tetraploid species (as Odontophrynus americanus) and the diploid Odontophrynus cordobae. Cruz, Feio, and Caramaschi, 2009, Anf. Ibitipoca: 72–73, provided (as Odontophrynus americanus) photographs and a brief account for Parque Estadual do Ibitipoca, Minas Gerais, Brazil. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf. Paraguay: 118, provided a brief account (as Odontophrynus americanus), image, and dot map for Paraguay. Grenat, Salas, Pollo, Otero, Baraquet, Sinsch, and Martino, 2018, Amphibia-Reptilia, 39: 1–10, reported on natural hybrids with Odontophrynus cordobae and Odontophrynus asper (as Odontophrynus americanus) in central Argentina hybrid zones. Martino, Dehling, and Sinsch, 2019, PeerJ, 7(e6480): 1–32, noted unnamed species (as Odontophryns americanus) in Misiones, Argentina, and Brazil. Martínez, Espínola, and Goossen, 2022, Bol. Mus. Nac. Hist. Nat. Paraguay, 26: 74–75, provided a record (as Odontophrynus americanus) from extreme southwestern Departamento Ñeembucú, Paraguay, and provided a dot map for that country. Resurrected by Rosset, Baldo, Borteiro, Kolenc, Cazzaniga, and Basso, 2022, Herpetol. Monogr., 36: 86, for the tetraploid populations formerly associated with the diploid Odontophrynus americanus. These authors also discussed the complex literature, systematics, distribution, comparative morphology, cytogenetics, advertisement and release calls.
