Taxonomic and nomenclatural notes on the coccolithophore Gephyrocapsa huxleyi (Noelaerhabdaceae, Haptophyta) and related species

Résumé

In our recent publication (Bendif & al. 2023), we established that the entity Gephyrocapsa huxleyi (widely known as Emiliania huxleyi) represents a group of at least three genetically delineated species. These were separated and proposed as: (1) Gephyrocapsa huxleyi (Lohmann) P.Reinhardt emend. Bendif, Probert, Beaufort, Rickaby & Archontikis; (2) Gephyrocapsa pseudohuxleyi Bendif, Probert, Beaufort, Rickaby & Archontikis sp. nov.; and (3) Gephyrocapsa pujosiae Verbeek comb. & stat. nov. emend. Bendif, Probert, J.R.Young, Beaufort, Rickaby & Archontikis, based upon an integrative approach combining morphological, phylogenetic, ecological and admixture data. However, several nomenclatural issues with respect to these entities have been brought to our attention and these are now formally addressed. Furthermore, three new subspecies of G. huxleyi (G. huxleyi subsp. regularis subsp. nov., G. huxleyi subsp. greenii subsp. nov. and G. huxleyi subsp. westbroekii subsp. nov.) and two new subspecies of G. pujosiae (G. pujosiae subsp. delicatissima subsp. nov. and G. pujosiae subsp. haginoae subsp. nov.) are formally proposed, in addition to the new combinations Gephyrocapsa pujosiae subsp. kleijneae comb. & stat. nov. and Gephyrocapsa pujosiae subsp. aurorae comb. & stat. nov.
