Derivation of names 

Wphvirus: derived from the name of the exemplar isolate Bacillus phage W.Ph., of the type species.

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.
