Thuridilla bayeri

Jim Anderson On 22 May, the following paper was published: Yonow, N. Opisthobranchs from the western Indian Ocean, with descriptions of two new species and ten new records (Mollusca, Gastropoda). Zookeys 197: 1â€"129. The new species are Cyerce borbonica (Polybranchiidae) and Doriopsilla nigrocera (Dendrodorididae). There are several important name changes in this publication and they should be adopted henceforth as they are proposed formally with adequate justification: Philinopsis cyanea (Martens) becomes a junior synonym of Philinopsis speciosa Pilsbry, 1860; Dolabella gigas (Rang) becomes a junior synonym of Dolabella auricularia (Lightfoot, 1786); Stylocheilus striatus (Quoy & Gaimard, 1832) becomes, once more, a junior synonym of Stylocheilus longicauda (Quoy & Gaimard, 1824);; Thuridilla bayeri Er. Marcus, 1965 and Thuridilla ratna Er. Marcus, 1965 both become junior synonyms of Thuridilla gracilis (Risbec, 1928); The correct original spelling of the species name for Thuridilla vatae is vataae, so it now becomes Thuridilla vataae (Risbec, 1928); Chromodoris cavae Eliot, 1904 is removed from synonymy under C. tennentana (Kelaart, 1859). Twenty species of Chromodorididae are included in this work under established genera. Since Yonow did not review genera in this work (except that for bullockii), my recommendation is that the changes in generic names suggested by R. Johnson & Gosliner (2012) for the chromodorids covered by Yonow be adopted even though Johnson & Gosliner predate Yonow’s by one month.

Deb Aston Jim can you explain in laymans terms why the name changes, is it lumpers and splitters at work or is dna the key? I am struggling to get a handle on this all.

Jim Anderson #Deb. Aren't we all! It seems to me to be all part of life's gay pageant (that's gay in the happy/gleeful sense) - science at work - changes happen.

Deb Aston Wish they would focus on naming the unnamed branchs for a while and not changing the ones we have already.
