Derivation of names

Siminovitchvirus: named in honour of Louis Siminovitch (1920 – ), a Canadian molecular biologist who studied phages early in his academic career.

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.
