Alphasatellites (family Alphasatellitidae) are circular, single-stranded DNA molecules (~1–1.4 kb) that encode a replication-associated protein and have commonly been associated with some members of the families Geminiviridae, Nanoviridae, and Metaxyviridae (recently established). Here, we provide a taxonomy update for the family Alphasatellitidae following the International Committee on Taxonomy of Viruses (ICTV) Ratification Vote held in March 2021. The taxonomic update includes the establishment of the new subfamily Petromoalphasatellitinae. This new subfamily includes three new genera as well as the genus Babusatellite, which previously belonged to the subfamily Nanoalphasatellitinae. Additionally, three new genera and 14 new species have been established in the subfamily Geminialphasatellitinae, as well as five new species in the subfamily Nanoalphasatellitinae.
