In order to reflect changes to the International Code of Virus Classification and Nomenclature (ICVCN) made by the International Committee on Taxonomy of Viruses (ICTV), NCBI taxonomy will introduce new binomial influenza species names like ‘Alphainfluenzavirus influenzae.’
Changes are expected to be in place near summer 2023.

Since the traditional influenza virus names like ‘Influenza A virus’ are broadly used, to minimize the impact of this change, the taxonomy schema will keep the former names in the lineages for each species; however, they will be moved below the (new) species taxa in the hierarchy.
See example below.

Former lineages

Genus Species
Alphainfluenzavirus Influenza A virus
Betainfluenzavirus Influenza B virus
Gammainfluenzavirus Influenza C virus
Deltainfluenzavirus Influenza D virus

New lineages

Genus Species Below species
Alphainfluenzavirus Alphainfluenzavirus influenzae Influenza A virus
Betainfluenzavirus Betainfluenzavirus influenzae Influenza B virus
Gammainfluenzavirus Gammainfluenzavirus influenzae Influenza C virus
Deltainfluenzavirus Deltainfluenzavirus influenzae Influenza D virus
