Glycera rouxii Audouin & Milne Edwards, 1833

Notes

Böggemann (2002) considers Glycera rouxii a synonym of Glycera unicornis Lamarck, 1818 (based on comparisons with original description as the holotype is lost). He considers the shape of the retractable branchiae (reported as bifid in Glycera unicornis ) not to be a diagnostic character, since variations were found in the same populations ( Böggeman, pers. comm.). However, Worsfold (2007) and Parapar and Moreira (2015) debate this synonymy and highlight differences in parapodial lobes besides those of the branchiae, although parapodial lobes were found to change between juvenile and adult specimens by Böggemann (2002). They propose that the branchial shape remains a diagnostic character, which should however be used with caution due to retractability. Despite the available evidence for the synonymy, two recent works consider both species as valid. Therefore, the past records of Glycera rouxii in Greece (see Supplementary material) are currently retained as separate, until a response to the arguments of Parapar and Moreira (2015) is available. Type locality: Mediterranean (Marseille).
