Homonomy of Doris luteola Kelaart, 1858

February 3, 2003
From: Michael Schroedl

Dear Bill,
I'd like to contribute the following matter for discussion.
All the best,
Michael Schroedl

Doris luteola Kelaart, 1858, a junior homonym of Doris luteola Couthouy in Gould, 1852

The nudibranch Doris luteola Kelaart, 1858 from the western Indian Ocean, currently placed into the genus Taringa (see Gosliner & Behrens, 1998), is a primary homonym of the Chilean Doris luteola Couthouy in Gould, 1852 (see Gould, 1852). Even though the latter species was considered to be a dubious species by Marcus (1959) and regarded to be not appropriate for reidentification (i.e. a nomen dubium) in a recent revision (Schrödl, 2000), Doris luteola Couthouy in Gould, 1852 was mentioned in several taxonomic lists e.g. by Carcelles (1950) and Carcelles & Williamson (1951; misspelled as Doris lucteola Gould, 1852), and Valdovinos (1995; as Doris luteola Gould, 1852). Thus, the junior name Doris luteola Kelaart, 1858 must be rejected. According to Article 60.2 of the Code (I.C.Z.N., 1999), it is proposed to replace Doris luteola Kelaart, 1858 by its junior synonym Thordisa caudata Farran, 1905 (see Farran, 1905; for synonymization see Eliot, 1906; Gosliner & Behrens, 1998).

Thanks Michael,
Apart from welcoming comments on the nomenclatural question you raise, I would also welcome comments om whether it is appropriate to publish messages such as this on the Forum. I know that there are a number of my colleagues who seem to think that websites are a highly inappropriate place for nomenclatural discussions such as this - and I have received a number of highly intemperate communications to that effect over the last few years. My feeling is that the Sea Slug Forum is a highly appropriate place for such discussions. While I would not post descriptions of new taxa on the Forum, I would certainly feel discussions on misidentifications, homonyms etc are better discussed on the Forum, with over 1000 visitors a day, than in some obscure publication, which is unknown or unavailable to most of us, but is considered 'appropriate' simply because it is printed on paper.

A photo of the two 'Doris luteola' would be nice.
Best wishes,
Bill Rudman
