• Notes:
  • 🥇 Nomenclatural type of the genus Nesiotobacter Donachie et al. 2006. Publication: Donachie SP, Bowman JP, Alam M. Nesiotobacter exalbescens gen. nov., sp. nov., a moderately thermophilic alphaproteobacterium from an Hawaiian hypersaline lake. Int J Syst Evol Microbiol 2006; 56:563-567.
  • ❗ Nesiotobacter exalbescens is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Nesiotobacter.
