Family: Polycipiviridae

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).
