Submitted by St. John, Emily

Family Nanoarchaeaceae

Etymology
[Na.no.ar.chae.a'ce.ae] N.L. neut. n. Nanoarchaeum, referring to the type genus Nanoarchaeum; -aceae, ending to denote a family; N.L. fem. pl. n. Nanoarchaeaceae, the Nanoarchaeum family
Nomenclatural type
Genus Nanoarchaeum
Description
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.
Classification
Archaea » Nanobdellota » Nanobdellia » Nanobdellales » Nanoarchaeaceae
