Proposal of Holzapfeliella gen. nov. and Litorivicinus gen. nov. as replacement names for the illegitimate prokaryotic generic names Holzapfelia Zheng et al. 2020 and Litoricola Kim et al. 2007, respectively

Abstract

The prokaryotic generic names Holzapfelia Zheng et al. 2020 and Litoricola Kim et al. 2007 are illegitimate because they are later homonyms of the names Holzapfelia Cossmann 1901, an extinct genus of molluscs (Neogastropoda) and Litoricola Woodward 1873, an extinct genus of crustaceans (Arthropoda), respectively (Principle 2 and Rule 51b(4) of the International Code of Nomenclature of Prokaryotes). We therefore propose the replacement generic name Holzapfeliella with type species Holzapfeliella floricola comb. nov. and the replacement generic name Litorivicinus with replacement name Litorivicinus lipolyticus for the type species, the replacement name Litorivicinus marinus, and the family name Litorivicinaceae to replace the illegitimate name Litoricolaceae Kim et al. 2007.

The best of both worlds: a proposal for further integration of Candidatus names into the International Code of Nomenclature of Prokaryotes

“…On the other hand, it would be necessary to ensure that the name proposed for valid publication is different from all registered Candidatus names. Again, this is good practice and is consistent with the objective of the ICNP to avoid homonyms, even homonyms of names proposed under the ICN [2] or ICZN [1], as implemented in Principle 2 [3]; validly published names that turn out to be homonyms of a botanical or zoological name are illegitimate and must be replaced [83–85]. Given the already established IJSEM Candidatus Lists [10, 11], it should be much easier for microbiologists to keep track of Candidatus names than to keep track of names proposed under the ICN or ICZN.…”

Reclassification of Allomuricauda and Muricauda species as members of the genus Flagellimonas Bae et al. 2007 and emended description of the genus Flagellimonas

“…Deshmukh and Oren [1] recently reclassified the members of the genus Muricauda ( Flavobacteriaceae , Flavobacteriales , Flavobacteriia , Bacteroidota ) in a newly proposed genus, Allomuricauda , as the genus name Muricauda Burns et al . 2001 is illegitimate (Principle 2 and Rule 51b(5) of the International Code of Nomenclature of Prokaryotes (ICNP) [2].…”

International Committee on Systematics of Prokaryotes: Subcommittee on the taxonomy of aerobic Bacteroidota. Minutes of the online meeting 25 April 2023

“…For example, the taxonomy of the genus Chryseobacterium has been redefined using genome-based taxonomy [4] and some of its species have been assigned to the genera Epilithonomonas, Kaistella, Halpernia and Soonwooa. The name Christiangramia is the replacement for the genus Gramella owing to it already being the name for fossil ostracods, described originally in 1971 [5]. The genus Flavobacterium is remarkable in that its number of species has now swelled to more than 300.…”
