The family Genomoviridae (phylum Cressdnaviricota, class Repensiviricetes, order Geplafuvirales) includes viruses with circular single-stranded DNA genomes encoding two proteins, the capsid protein and the rolling-circle replication initiation protein. The genomes of the vast majority of members in this family have been sequenced directly from diverse environmental or animal- and plant-associated samples, but two genomoviruses have been identified infecting fungi. Since the last taxonomic update of the Genomoviridae, a number of new members of this family have been sequenced. Here, we report on the most recent taxonomic update, including the creation of one new genus, Gemytripvirus, and classification of ~420 new genomoviruses into 164 new species. We also announce the adoption of the “Genus + freeform epithet” binomial system for the naming of all 236 officially recognized species in the family Genomoviridae. The updated taxonomy presented in this article has been accepted by the International Committee on Taxonomy of Viruses (ICTV).
