Thurstonella, replacement name for the Antarctic amphipod genus Clarencia K.H. Barnard, 1931 (Crustacea, Amphipoda, Thurstonellidae), preoccupied by Clarencia Sloane, 1917 (Insecta, Coleoptera, Carabidae)

Abstract

The generic name Clarencia was originally proposed by Sloane (1917) for a genus of carabid beetles (Insecta, Coleoptera, Carabidae). It is a valid name in current use for a small endemic genus of Australian/Papua New Guinean ground beetles, recently revised by Baehr (2005). Clarencia K.H. Barnard, 1931, was established as a monotypic genus of Antarctic amphipods. Shaw (1989) and Zeidler (1994) have both redescribed Clarencia chelata K.H. Barnard, 1931. Zeidler (1994) re-diagnosed the family Clarenciidae Barnard & Karaman, 1987 and set up the superfamily Clarencioidea. It was recently brought to our attention that Clarencia K.H. Barnard, 1931 is a junior homonym of Clarencia Sloane, 1917. The new name, Thurstonella, is proposed to replace Clarencia K.H. Barnard, 1931. Because the type genus of the family is a junior homonym, the family group name Clarenciidae Barnard & Karaman, 1987, is replaced with Thurstonellidae, in accordance with Article 39 of the International Code of Zoological Nomenclature (1999, fourth edition).
