Checked: verified by a taxonomic editorNomenclature Spio caudatus Lamarck, 1818 may appear to be simply the senior homonym to "Spio caudatus Delle Chiaje, 1827", a nereidid, as explained in Imajima (1972:107) who states Delle Chiaje's name is preoccupied. However, the history is more complex. Lamarck's name was an unnecessary replacement name for the valid Polydora cornuta. While invalid, it is still an available name by indication (art. 12.2.3, an apparent exception to art. 11.5 that names must be valid when proposed), and cannot be excluded from homonymy (art. 54.2). However, that is not relevant. Even if it was excluded, Neanthes caudata (sensu delle Chiaje, 1827) would not as a consequence become a valid name because it is a usage of the existing Lamarck name based on a misidentification (see Spio caudatus sensu delle Chiaje). Pettibone (1963:162) correctly and simply presented the Spio caudatus usage of Delle Chiaje as not Lamarck's species. She did not regard it as a homonym, although Hartman catalogue labelled it as such. [G. Read original analysis, Jan 2016] [details]
