Nomenclature Hydroides affinis was previously annotated as a nomen oblitum in WoRMS. However, reversal of precedence (Art.23.9) in favour of Hydroides helmata cannot be applied for this name as it has been used more than once since 1899, most recently as valid by Zibrowius (1968:115) [details]

Taxonomy Zibrowius included H. affinis in H helmata and commented: "Comme nous l'avons déjà démontré dans un travail antérieur (ZlBROWIUS, 1968) l'opercule de Hydroides affinis (MARION, 1875; GOURRET, 1901; non mentionné dans le catalogue de HARTMAN, 1959, 1965) ressemble beaucoup à celui de H. helmata tout en comportant des dilatations sur le bord dorsal du grand crochet. Ce dernier détail n'a été observé sur aucun des spécimens étudies. H. affinis semble, néanmoins, être un spécimen aberrant de H. helmata." [details]

Editor's comment It appears H. affinis (Marion, 1875) needs to be dealt with again in a publication to consider its status as a name, as it clearly has priority over H. helmata (Iroso, 1921). Meantime the taxon it represents is placed here as a taxon inquirendum. [details]Grammatical gender Agreement: Masculine and feminine forms of the adjective 'affinis' are identical. [details]
Nomenclature Hydroides affinis was previously annotated as a nomen oblitum in WoRMS. However, reversal of precedence (Art.23.9) in favour of Hydroides helmata cannot be applied for this name as it has been used more than once since 1899, most recently as valid by Zibrowius (1968:115) [details]
Synonymy Zibrowius (1971) placed Hydroides affinis under Hydroides helmata (Iroso, 1921), the better known name, however H. affinis is senior [details]
Taxonomy Zibrowius included H. affinis in H helmata and commented: "Comme nous l'avons déjà démontré dans un travail antérieur (ZlBROWIUS, 1968) l'opercule de Hydroides affinis (MARION, 1875; GOURRET, 1901; non mentionné dans le catalogue de HARTMAN, 1959, 1965) ressemble beaucoup à celui de H. helmata tout en comportant des dilatations sur le bord dorsal du grand crochet.
