Huber et al., 2016: The “Nanoarchaeaceae” represent one of the two families within the “Nanoarchaeales”. They are extremely tiny cocci with reduced genomes. They are hyperthermophilic and anaerobic. They form a close association with their hosts and their growth depends on metabolic products of their host cells. Only one representative is cultivated in the laboratory.

Kato et al., 2022: Reassigned Nanoarchaeum equitans to the class Nanobdellales, following effective publication of Nanobdella aerobiophila as the type strain for the entire phylum.
