Proposal of Thalassovita gen. nov. and Alloyangia gen. nov. as replacement names for the illegitimate prokaryotic generic names Thalassobius and Yangia, respectively

Int J Syst Evol Microbiol. 2023 Sep;73(9). doi: 10.1099/ijsem.0.006025.


The prokaryotic generic names Thalassobius Arahal et al. 2005 and Yangia Dai et al. 2006 are illegitimate because they are later homonyms of the genus names Thalassobius Solier 1849 (Coleoptera) and Yangia Zheng 1997 (fossil Rodentia), respectively Principle two and Rule 51b(4) of the International Code of Nomenclature of Prokaryotes]. We therefore propose the replacement generic names Thalassovita and Alloyangia, with type species Thalassovita gelatinovora and Alloyangia pacifica, respectively.

Keywords: Thalassobius; Yangia; illegitimate names.
