# Proposal of Allobrachymonas gen. nov. and three new combinations as replacement names for the illegitimate prokaryotic genus name Brachymonas, proposal of Allobosea gen. nov. and 12 new combinations as replacement names for the illegitimate prokaryotic genus name Bosea and proposal of Alloboseaceae fam. nov. as a replacement name for the illegitimate family name Boseaceae

## TL;DR

This paper proposes new names for prokaryotic genera and families to resolve naming conflicts with existing names in other biological groups.

## Contribution

The paper introduces new valid names to replace previously illegitimate prokaryotic genus and family names.

## Key findings

- The names Brachymonas and Bosea are illegitimate due to homonym conflicts.
- Allobrachymonas, Allobosea, and Alloboseaceae are proposed as valid replacements.
- Three new combinations are proposed for Allobrachymonas and 12 for Allobosea.

## Abstract

The prokaryotic generic names Brachymonas Hiraishi et al. 1995 and Bosea Das et al. 1996 are illegitimate because they are later homonyms of the genus names Brachymonas Grassé 1952 (Protozoa, Polymastigidae) and Bosea He and Qian 1979 (a fossil dinoflagellate) [Principle 2 and Rule 51b(4) of the International Code of Nomenclature of Prokaryotes (ICNP)]. We therefore propose the replacement names Allobrachymonas gen. nov., Allobrachymonas chironomi comb. nov., Allobrachymonas denitrificans comb. nov., Allobrachymonas wangyanguii comb. nov., Allobosea gen. nov., Allobosea beijingensis comb. nov., Allobosea caraganae comb. nov., Allobosea eneae comb. nov., Allobosea lathyri comb. nov., Allobosea lupini comb. nov., Allobosea massiliensis comb. nov., Allobosea minatitlanensis comb. nov., Allobosea psychrotolerans comb. nov., Allobosea robiniae comb. nov., Allobosea rubneri comb. nov., Allobosea spartocytisi comb. nov., Allobosea thiooxidans comb. nov., Allobosea vaviloviae comb. nov., Allobosea vestrisii comb. nov. and Alloboseaceae fam. nov.
