Nomenclature; taxonomy; Amphibia; plethodontidae; salamanders; Hydromantes; Hydromantes genei; Hydromantes platycephalus; Italy; France; Sardinia; California. Ruling (1) Under the plenary powers: (a) the name Geotriion Bonaparte, [1832] is hereby suppressed for the purposes of the Principle of Priority but not for those of the Principle of Homonymy; (b) all previous fixations of type species for the nominal genus Hydromantes Gistel, 1848 are hereby set aside and Spelerpes platycephalus Camp, 1916 is designated as the type species. (2) The name Hydromantes Gistel, 1848 (gender: masculine), type species by designation under the plenary powers in (l)(b) above Spelerpes platycephalus Camp, 1916, is hereby placed on the Official List of Generic Names in Zoology. (3) The name platycephalus Camp, 1916, as published in the binomen Spelerpes platycephalus (specific name of the type species oi Hydromantes Gistel, 1848), is hereby placed on the Official List of Specific Names in Zoology. (4) The following names are hereby placed on the Official Index of Rejected and Invalid Generic Names in Zoology: (a) Geotriton Bonaparte, [1832], as suppressed in (l)(a) above; (b) Hydromantoides Lanza & Vanni, 1981 (a junior objective synonym of Hydromantes G'\sit\, 1848). History of Case 2868 An application to conserve the usage of the name Hydromantes Gistel, 1848 by the designation of Salamcmdra genei Temminck & Schlegel, 1838 as the type species of the genus was received from Prof Hobart M. Smith ( University of Colorado. Boulder, Colorado, U.S.A.) and Dr David B. Wake (Museum of Vertebrate Zoology, University of California. Berkeley, California. U.S.A.) on 16 November 1992. After correspon-dence the case was published in BZN 50: 219-223 (September 1993). Notice of the case was sent to appropriate journals. It was noted on the voting paper that Bonaparte ([1832]) established Geotriton based on the nominal species Salamandra e.xigua Laurenti, 1768. Dunn (1923) and Dubois (1984) accepted S. e.xigua as a salamandrid, and Duellman & Trueb (1986) treated Geotriton as a junior synonym of Triturus Rafinesque, 1815 (= Triton Laurenti, 1768) in the salamandridae. Geotriton was used as a valid name until 1923 and included species now placed in the plethodontidah; Bonaparte ([1837]) included ' Salamandra fusca Laurenti, 1 768' (a misidentification of Hydromantes italicus Dunn, 1923) and Tschudi ([1838]) placed Salamandra genei Temminck & Schlegel, 1838 in the genus. Dubois (1984; see also BZN 52: 185, para. 4) considered that Bonaparte's ([1832]) use oi ' Salamandra e.xigua' as the basis of Geotriton was a misidentification of Hydromantes italicus, like his ([1837]) use of 'S. fusca'.
