Nereis pulsatoria (Savigny, 1822) 

Nereis pulsatoria  (Savigny, 1822) | Nereis zonata  Malmgren, 1867


The taxonomy and nomenclature of Nereis pulsatoria  and Nereis zonata  are confused. In literature, both Nereis pulsatoria  (Savigny, 1822) and Nereis pulsatoria  Audouin & Milne Edwards 1834 are used (the latter not as a new name but as a reference to Savigny's species, thus not a homonym). It is currently unclear whether these two actually refer to the same species. Fauvel (1923) considers Nereis pulsatoria  Audouin & Milne Edwards 1834 a synonym of Nereis zonata  but does not mention Savigny's species. Núñez (2004) synonymises Nereis zonata  Malmgren 1867 and Nereis pulsatoria  Audouin & Milne Edwards, 1834 with Nereis pulsatoria  (Savigny 1822), but without any mention of studied material or reference to the original description. Gravina et al. (2015) point out that the description of Nereis pulsatoria  by Núñez (2004) is inconsistent when compared to the corresponding illustrations and that the described species differs from Nereis zonata  in chaetal and paragnath arrangement. Gravina et al. (2015) consider only Savigny's species valid and restrict it to the Atlantic, but the authors base this statement on the respective species entries in WoRMS, which have not been reviewed recently, contain partly incorrect information and may constitute database inconsistencies. If the species are indeed synonymous, Nereis pulsatoria  , being the older name, should have priority over Nereis zonata  . Until this confusion is resolved, the name Nereis pulsatoria  is kept here and Nereis zonata  considered its synonym. Specimens from Greece have both been reported under the name Nereis zonata  and Nereis pulsatoria  sensu Núñez (2004).
