Nomenclature We cite here Van Soest et al.'s (2020: 20-21) explanation for the proposed nomen novum.
Removal of homonymy between Halichondria cristata (Ellis & Solander, 1786) and Spongia (Heterofibria) cristata Cook & Bergquist, 2001.
1. Spongia cristata Ellis & Solander, 1786: 186 (type locality Hastings, United Kingdom). Spongia cristata Ellis & Solander, 1786 is a senior primary homonym of Spongia (Heterofibria) cristata Cook & Bergquist, 2001 (ICZN Art. 57.2). Ellis & Solander’s (1786) species refers to Ellis’s (1766: Plate XI Fig. G) ‘cockscomb sponge’ which is clearly synonymous with Halichondria (Halichondria) panicea (Pallas, 1766) (with additional sources Montagu 1814: 103; WPD 2019).
2. Spongia (Heterofibria) cristata Cook & Bergquist, 2001: 37 (type locality Hauraki Gulf, New Zealand). Spongia (Heterofibria) cristata Cook & Bergquist, 2001 is the type species of Spongia (Heterofibria) Cook & Bergquist, 2001 but also a junior primary homonym of Spongia cristata Ellis & Solander, 1786, requiring a new name (ICZN Art. 57.2 & 60.1). It may be considered that replacing the name is a ‘threat to nomenclatural stability’ of the subgenus Spongia (Heterofibria) and ICZN Art. 23.9.3 should be invoked. However, the junior homonym and the replacement name are objective synonyms and they share the same type specimen (ICZN Art. 72.7) ensuring stability of the subgenus Spongia (Heterofibria).
3. Summary: Halichondria cristata (Ellis & Solander, 1786) is a senior primary homonym of Spongia (Heterofibria) cristata Cook & Bergquist, 2001 (ICZN Art. 57) and is now accepted as a synonym of Halichondria (Halichondria) panicea (Pallas, 1766). Spongia (Heterofibria) cristata Cook & Bergquist, 2001 is the junior primary homonym of Spongia cristata Ellis & Solander, 1786 (ICZN Art. 60.1), and required a new name, for which Spongia (Heterofibria) decooki nom. nov. was proposed, named after Steve de Cook.
