Odontophrynus Reinhardt and Lütken, 1862
Odontophrynus Reinhardt and Lütken, 1862 "1861", Vidensk. Medd. Dansk Naturhist. Foren., Ser. 2, 3: 159. Type species: Odontophrynus cultripes Reinhardt and Lütken, 1862, by monotypy.
Hyperoodon Philippi, 1902, Supl. Batr. Chil. Descr. Hist. Fis. Polit. Chile: 1. Type species: Hyperoodon asper Philippi, 1902, by monotypy. Preoccupied by Hyperoodon Lacèpéde, 1804 (Cetacea). Synonym with Paludicola Wagler by Boulenger, 1903, Zool. Rec., 39: 29. Considered a nomen dubium, possibly in Paludicola by Nieden, 1923, Das Tierreich, 46: 513. Synonymy by Cei, 1958, Invest. Zool. Chilen., 4: 266.
Southern and eastern South America.
Savage and Cei, 1965, Herpetologica, 21: 178-195, reviewed the genus. Beçak and Beçak, 1974, J. Herpetol., 8: 337–341, discussed phylogeny in the genus. Cei, 1970, Acta Zool. Lilloana, 27: 181–192, suggested a distant relationship between Odontophrynus and the remaining ceratophryids (sensu stricto). Brandão and Batista, 2000, Iheringia, Zool., 89: 165–171, implied a relationship of Odontophrynus with Proceratophrys on the basis of larval morphology. Rosset, Baldo, Lanzone, and Basso, 2006, J. Herpetol., 40: 465–477, discussed the ranges of diploid and tetraploid members of the Odontophrynus americanus complex and noted an undescribed species in northeastern Argentina, Uruguay, eastern Paraguay, and southern Brazil, formerly confused with Odontophrynus cordobae. Amaro, Pavan, and Rodrigues, 2009, Zootaxa, 2071: 61–68, demonstrated that Macrogenioglottis is phylogenetically imbedded within Odontophrynus. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583, in their study of Genbank sequences, suggested that Macrogenioglottus is the sister taxon of Odontophrynus. Nascimento, Mott, Langone, Davis, and de Sá, 2013, Zootaxa, 3700: 140–158 reported on comparative larval morphology within the genus.
