Distinguishing features
Iflavirus infections are limited to arthropods, predominantly within the class Insecta.
Species demarcation criteria
Sequence identity at the amino acid level between the capsid proteins of isolates and strains of a species is above 90%. Note that, by this definition, Laodelphax striatella honeydew virus 1 and Laodelphax striatellus iflavirus 2 (related, unclassified species) are the same species. The Iflaviridae family is expanding rapidly and will likely undergo revision in the near future.
Member species
Derivation of names
Ifla: siglum derived from the type species, Infectious flacherie virus.
