Sphaerolipoviridae is a family of double-stranded DNA viruses that infect thermophilic bacteria and halophilic archea, formally approved by the International Committee on Taxonomy of Viruses in 2015. Viruses of this family have tailless icosahedral virions with an internal lipid membrane located between the protein capsid and the double-stranded DNA genome. Overall virion organization of sphaerolipoviruses is similar to that of viruses belonging to the families Tectiviridae, Corticoviridae and Turriviridae.
There are three genera in this family. Members of the genera Alphasphaerolipovirus and Betasphaerolipovirus infect halophilic archaea, while those of the genus Gammasphaerolipovirus replicate in thermophilic bacteria.
