Technical Abstract: The iflaviruses comprise viruses isolated from arthropod species of agricultural importance. All members of iflaviruses have a genome arrangement similar to the picornaviruses, ootyviruses, and secoviruses. However, phylogenetic analysis using the RNA-dependent RNA polymerase region showed that the iflaviruseses form a monophyletic group distantly related to the dicistroviruses, picornaviruses, mamaviruses, and secoviruses. As a result, the iflaviruses will be included in the 9th Report of the International Committee on Taxonomy of Viruses (ICTV) as members of a new virus family, Iflaviridae. The chapter, Iflaviridae, as a part of the 9th ICTV report summarizes the 1) taxonomic structure, 2) virion properties, 3) genome organization and replication, 4) antigenic properties, and 5) biological properties of the Iflaviridae. The phylogenetic relationship within the family and similarity with other taxa are also discussed. The new ICTV report provides an effective way to update the state of virus taxonomy and should be of interest to the virus research community.
