Genus: Sopolycivirus

Genus: Sopolycivirus

Distinguishing features

Among currently classified members of the family, sopolyciviruses are distinguished by the presence of ORF2b overlapping the 5′-end of ORF2; ORF2b encodes a small protein with a predicted transmembrane domain (Olendraite et al., 2017). Most (possibly all) members of the genus appear to infect ants (family Formicidae).

Derivation of names

Sopolyci: from the type species Solenopsis invicta virus 2 and polycipivirus.

Species demarcation criteria

Formal species demarcation criteria have not yet been established. ORF5-encoded amino acid sequence identity between isolates and strains of a species is above 90%.
