Members of the genus Etatorquevirus have genomes of 2 kb and have been identified in members of the felid (Felidae) and civet (Viverridae) families.
Different species in the genus have orf1 genes with <69% pairwise identity.
The only species in the genus Epsilontorquevirus includes a virus with a genome of about 3.3 kb identified in a cotton-top tamarin (species Saguinus oedipus, family Callitrichidae).
Different species in the genus have orf1 genes with <69% pairwise identity.
The only species in the genus Deltatorquevirus includes a virus with a genome of about 2.2 kb identified in a Northern tree shrew (species Tupaia belangeri chinensis, family Tupaiidae).
Different species in the genus have orf1 genes with <69% pairwise identity.
The only species in the genus Chitorquevirus includes a virus with a genome of about 2.5 kb identified in a lemur (species Indri indri, family Indriidae).
Different species in the genus have orf1 genes with <69% pairwise identity.
Members of the genus Betatorquevirus have genomes of 1.7–2.9 kb and have been identified in humans.
Different species in the genus have orf1 genes with <69% pairwise identity.
The only species in the genus Ayintorquevirus includes a virus with a genome of about 2.1 kb which was identified in a grizzly bear (family Ursidae).
