Mercediella nom. nov., a replacement name for Camposichthys Figueiredo & Silva Santos, 1991 (Pisces: Pycnodontiformes)

摘要

Camposichthys has been published three times for genera of bony fishes, generating a triple homonymy which is described and analyzed in this paper. A replacement name for the youngest homonym is presented. Travassos (1946) was the first to errect Camposichthys and did so on some erroneous assumptions regarding the then complicated status of Cynodon Spix in Spix & Agassiz, 1829, Raphiodon Agassiz in Spix & Agassiz, 1829, and Rhaphiodonichthys Campos, 1945 (see Kottelat 1988). In Opinion 2012, the International Commission on Zoological Nomenclature (2002) considered Camposichthys Travassos, 1946, to be a junior objective synonym of Cynodon Spix in Spix & Agassiz, 1829, and placed it in the 'Official Index of Rejected and Invalid Generic Names in Zoology'. Despite this nomenclatural act, in accordance with § 80.7.1 of the current version of the Code (ICZN 1999) this name continues to compete in homonymy.
