"Candidatus Lokiarchaeum" is the first discovered genus of Promethearchaeati, the kingdom from which eukaryotes emerged. It belongs to the family Promethearchaeaceae and contains the species "Ca. Lokiarchaeum primum" and "Ca. Lokiarchaeum ossiferum".

Taxonomy

"Ca. Lokiarchaeum" was described in 2015 and was assigned to the phylum "Lokiarchaeota".[2] In 2017, "Lokiarchaeota" was assigned to the superphylum "Asgard", as well as other phyla.[3] Later, the superphylum "Asgard" was de-ranked to the phylum "Asgardarchaeota".[4] In 2023, the species "Ca. Lokiarchaeum ossiferum" was described.[5] In 2024, "Asgardarchaeota" was renamed to Promethearchaeota.[6] In 2025, the unclassified species GC14_75 was pro-validly[7] published as a type species "Ca. Lokiarchaeum primum" in Candidatus List No. 7, with the authority "Spang et al. 2015".[8]
