The genus Gyrovirus was assigned to the family Anelloviridae in 2017 with only one recognized species, Chicken anemia virus. Over the last decade, many diverse viruses related to chicken anemia virus have been identified but not classified. Here, we provide a framework for the classification of new species in the genus Gyrovirus and communicate the establishment of nine new species. We adopted the 'Genus + freeform epithet' binomial system for the naming of these species.
