Augarchaeota

"Augarchaeota" 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 αυγή, 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".
