Interpretive Summary:

Technical Abstract: A transparent and functional system for virus classification is essential to allow scientists to correctly identify and report on viruses detected in different hosts or locations without ambiguity. New research into relationships between previously characterized and newly-emerging viruses may require creation of new families, genera, and species to reflect increased knowledge. Newly reported viruses have been discovered that are distinct from other viruses in the order Tymovirales, and from species and genera in the families Alphaflexiviridae, Betaflexiviridae, and Gammaflexiviridae, but are otherwise phylogenetically most closely related to these families, based on the phylogenetic relationships of the replication protein. A new family, the Deltaflexiviridae, and genus, Deltaflexivirus, are therefore proposed to include three new species, which are provisionally named Sclerotinia deltaflexivirus 1, Soybean-associated deltaflexivirus 1, and Fusarium deltaflexivirus 1. Creation of the new family, genus, and three new species will aid the maintenance of a transparent and functional viral taxonomy for unambiguous naming of viruses.
