Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
* ''Alphaturrivirus hveragerdiense'',

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. ''Sulfolobus solfataricus'' serves as the natural host. Transmission routes are passive diffusion.[
