"Augarchaeota" (previously "Aigarchaeota") is an archaeal phylum of which the main representative is "Candidatus Caldiarchaeum subterraneum".. It is not yet clear if this represents a new phylum or a Nitrososphaeria class, since the genome of "Ca. Caldiarchaeum subterraneum" encodes several Nitrososphaeria-like features.. The name "Aigarchaeota" comes from the Greek , avgí, meaning "dawn" or "aurora", for the intermediate features of hyperthermophilic and mesophilic life during the evolution of its lineage. The prefix Aig was found to be a misspelling, and corrected to Aug, thereby the new name "Augarchaeota".
