Kim, Ji Hee & Division, Han-Gu Choi, 2024, Carolibrandtia antarctica (Fritsch) H. Chae, H. - G. Choi & Ji Hee Kim, comb. nov. (Chlorellaceae, Trebouxiophyceae), Notulae Algarum 317, pp. 1-2 : 1-2

Carolibrandtia antarctica (Fritsch) H.Chae, H.-G.Choi & Ji Hee Kim , comb. nov.

Basionym: Chlorosphaera antarctica Fritsch , Journal of the Linnean Society of London, Botany 40: 302 (English), 324 (Latin), pl. 10: figs 2-6; pl. 11, photos. 1, 3, 5, 6, C, 1912.

Lectotype for Chlorosphaera antarctica Fritsch (here designated): [!icon] Journal of the Linnean Society of London Botany 40: pl. 10: fig. 2, 1912.

Epitype for above lectotype (here designated): cryopreserved, metabolically inactive material from culture CCAP 211 /45 lodged at CCAP ( Culture Collection of Algae and Protozoa , SAMS, Ltd, Oban, Scotland) .

Registrations: http://phycobank.org/104341 (name), http://phycobank.org/104339 (lectotype), http://phycobank.org/104340 (epitype).

Representative strain: CCAP 211/45, as Chlorella antarctica (Fritsch) Wille , collected from an unknown site in Antarctica by Sutton in 1970.

Note: Chlorosphaera antatctica Fritsch was recently transferred to the genus Carolibrandtia R. Hoshina & Nakada, 2018 , as Carolibrandtia antarctica (Fritsch) H.Chae, H.-G.Choi & Ji Hee Kim in Algae 38(4): 248. 2023, nom. inval. (ICN, Art. 41.5), utilizing the same strain as the above-designated epitype. This reclassification is based on phylogenetic analysis and the secondary structure of the small subunit ribosomal RNA gene, as detailed in Chae & al. (2023). However, there was an error in the new combination; figs 2-6 from Fritsch (1912) were mistakenly cited as the holotype, accompanied by some inaccuracies in the literature citations.

The authors wish to extend their gratitude to Wolf-Henning Kusber for highlighting the issues with the new combination and for offering valuable insights on this matter. We also thank Michael D. Guiry for his valuable advice on typification and for his assistance in enhancing the quality of the manuscript. Additionally, we acknowledge Jo Wilbraham for her efforts in searching for Fritsch’s original material within the Natural History Museum collection (BM) and for confirming its unavailability. This work was supported by KOPRI ( Korea Polar Research Institute) grant funded by the Ministry of Oceans and Fisheries, Project no. PE24130.
