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.

English Names

None noted.

Distribution

Central and northern Argentina (from Buenos Aires and La Pampa provinces to the northern part of the country), Uruguay, southern Paraguay (Central and Itapúa departments), and southeastern Brazil (Minas Gerais, Paraná, Rio Grande do Sul, Santa Catarina, and São Paulo states; probably also occurs in Bolivia.

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.
