Family: Nipumfusiviridae

Genus: Yangshanfusivirus

The genus Yangshanfusivirus (family: Nipumfusiviridae) includes a single species (Yangshanfusivirus mimetica) for a virus identified via metagenomic sequencing of viral communities in the deep-water environment of Yangshan Harbour, China.

Demarcation criteria for taxa within the genus

Viruses belonging to additional species in the genus will differ by showing ≤95% average nucleotide identity in pairwise comparisons with established species while maintaining ≥50% mean amino acid identity across all orthologs and conserving both the major capsid protein and ATPase to qualify as genus members.
