The family contains one genus, ''Alphaguttavirus'', which contains one species: Aeropyrum pernix ovoid virus 1 (''Betaguttavirus kodakarajimaense'').

Taxonomy

The family currently contains one genera and species: * ''Betaguttavirus'' ** Aeropyrum pernix ovoid virus 1 (''Betaguttavirus kodakarajimaense'') Genus ''Alphaguttavirus'' and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.

Structure

Viruses in the family ''Guttaviridae'' are enveloped. The diameter is around 55–80 nm, with a length of 75–130 nm. Genomes are circular double-stranded DNA around 14 kilobases in length. Virions are ovoid or droplet-shaped and covered with globular subunits.

Life cycle

DNA-templated transcription is the method of transcription. Archaea serve as the natural host.
