1 species

Peltocephalus Tschudi, 1838, Classif. Batr.: 81. Type species: Peltocephalus quoyi Tschudi, 1838, by monotypy. The name is ascribed by Tschudi in the original publication to Bibron, but presumably the diagnosis is Tschudi’s. Preoccupied by Peltocephalus Duméril and Bibron, 1835. Synonymy with Calyptocephalus by Guichenot, 1848, in Gay (ed.), Hist. Fis. Polit. Chile, Zool., 2: 107; Jiménez de la Espada, 1875, Vert. Viaje Pacif. Verif. 1862–1865: 2; Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 180.

Calyptocephalus Duméril and Bibron, 1841, Erp. Gen., 8: 447. Type species: Calyptocephalus gayi Duméril and Bibron, 1841, by monotypy. Primary junior homonym of Calyptocephalus Gray, 1832 (Coleoptera).

Cephalopeltis Jiménez de la Espada, 1875, Vert. Viaje Pacif. Verif. 1862–1865: 2. Replacement name for Calyptocephalus erroneously cited to Duméril and Bibron, 1841, Erp. Gen., 8: 447. Nomen oblitum.

Calyptocephala Nieden, 1923, Das Tierreich, 46: 371. Replacement name for Calyptocephalus Duméril and Bibron, 1841. Primary junior homonym of Calytpocephala Dejean, 1834 (Coleoptera).

Calyptocephalella Strand, 1928, Arch. Naturgesch., Abt. A,, 92: 55. Replacement name for Calyptocephala Nieden, 1923.

Eophractus Schaeffer, 1949, Bull. Am. Mus. Nat. Hist., 93: 49. Type species: Eophractus casmayorensis Schaeffer, 1949. Fossil taxon. Synonymy by Lynch, 1971, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 53: 116.

Gigantobatrachus Casamiquela, 1958, Rev. Asoc. Geol. Argentina, 13: 174. Type species: Gigantobatrachus parodii Casimequela, 1959, by original designation. Fossil taxon. Synonymy by Lynch, 1971, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 53: 116.

Comment

Myers and Stothers, 2006, Arch. Nat. Hist., London, 33: 255-256, discussed the earlier nomenclatural discussions of Myers, 1962, Copeia, 1962: 195-202, Donoso-Barros and Cei, 1962, Herpetologica, 18: 195-203, and Lynch, 1971, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 53: 1-238m and concluded that Caudiverbera Laurenti, 1768, Spec. Med. Exhib. Synops. Rept.: 43 (type species: Caudiverbera peruviana Laurenti, 1768 [= Lacerta caudiverbera Linnaeus, 1758], by subsequent designation of Stejneger, 1936, Copeia, 1936: 135) is based on a fictitious animal and therefore unavailable for scientific nomenclature. They recommended the use of the name Calyptocephalella gayi as the appropriate name for this species. See comment under Telmatobufo. Formas and Espinoza, 1975, Herpetologica, 31: 429-432, suggested karylogical evidence for a close relationship of Telmatobufo and Calyptocephalella (as Caudiverbera).
