Lenarviricota is a phylum of RNA viruses, which includes all positive-strand RNA viruses, which infect prokaryotes.[1] Some members also infect eukaryotes.[2] The name of the group is a portmanteau of the names of member families "Leviviridae and Narnaviridae" and -viricota which is the suffix for a virus phylum.[3] It has been suggested that the origin of Lenarviricota may predate that of the last universal common ancestor (LUCA).[4]
