Members of the family Satyavativiridae are dsDNA viruses associated with the host Poseidoniales, a marine archaeal lineage. Genomes assigned to this group have been identified via long-read sequencing of brackish estuarine samples. These viruses represent a novel viral lineage in the order Adrikavirales distinct from other Poseidoniales viruses known as 'magroviruses', a collective term derived from Marine Group II Euryarchaeota (former name of Poseidoniales) viruses. The family includes the genus Vyasavirus and the species Vyasavirus brisbanense. The virus genome is a linear dsDNA of 87 kbp and encodes proteins involved in the morphogenesis of virions, which are predicted to be composed of an icosahedral capsid and helical tail, characteristic of members of the class Caudoviricetes. This is a summary of the International Committee on Taxonomy of Viruses Report on the family Satyavativiridae, which is available at ictv.global/report/satyavativiridae.
