Derivation of names 

Silviavirus: indirectly derived from the exemplar isolate, Staphylococcus phage Remus, of the type species. In Roman mythology, Silvia was the mother of Romulus and Remus, after which two phage strains belonging to the type species were named.

Species demarcation criteria 

Members of the same species are more than 95% identical in genome nucleotide sequence, including the terminal repeat region. Phages with genomes that differ by more than 5% are assigned to different species.
