[2][1][3] The following list is a map of T4virus species according to ICTV Version 2022[1] Group: dsDNA The virions of Schizotequatrovirus are nonenveloped, with a head and tail.

The virus attaches to the host cell using its terminal fibers, and uses viral exolysin to degrade the cell wall enough to eject the viral DNA into the host cytoplasm via contraction of its tail sheath.

Once the viral genes have been replicated, the procapsid is assembled and packed.

At the same time, Vibrio phage nt-1 was moved into the genus from its previous classification in T4-like viruses (now T4virus).

In 2019, with Master Species List 34, the genus was renamed again, now to Schizotequatrovirus[1]
