Checked: verified by a taxonomic editorType species Confusion exists over the type species of Scaeurgus, its resolution having significant taxonomic implications. In his list of cephalopod generic names, Hoyle (1910) used page priority (‘sp. first named’) to designate S. titanotus (= Pteroctopus tetracirrhus) as the type species of Scaeurgus. Under the International Code of Zoological Nomenclature (ICZN, 1999: art. 24.2.1), Hoyle’s type determination is valid. As a result, tetracirrhus Chiaie, 1830 (the type species of the genus Pteroctopus) becomes also the type species for the older generic name, Scaeurgus.
There are three implications: (1) the genus Pteroctopus should be placed in the synonymy of the genus Scaeurgus,
(2) tetracirrhus should be treated as a species of Scaeurgus, and
(3) a new genus should be coined for unicirrhus, patagiatus and the new taxa reported in Norman et al. (2005).
Robson (1929) was aware of this name priority issue but chose to disregard it: ‘As I think it is quite clear that Troschel's titanotus is delle Chiaje's [sic] tetracirrhus, and as it is proposed to maintain Fischer's genus [Pteroctopus], it follows that unicirrhus must be regarded as the genotype of Scaeurgus’ (p. 191–192). Robson and subsequent authors followed this convention through to the present day. Due to the long usage of the two names Pteroctopus and Scaeurgus and their component species, particularly in the Mediterranean Sea, Norman et al. (2005) believe that disruption of these generic names will only cause unnecessary confusion, and propose to maintain the historical conventions since Robson (1929) that unicirrhus remain the type species for Scaeurgus. As a result, tetracirrhus would be retained as the type species for the distinct genus Pteroctopus. A submission to ICZN supporting this proposal is pending.
