Family: Solinviviridae

Genus: Nyfulvavirus

Distinguishing features

The sole member of the only species in this genus infects ants and has a genome organisation characterised by a single major ORF. This contrasts with the genome organisation of Solenopsis invicta virus 3 (genus Invictavirus), which has two major ORFs with ribosomal frameshifting used to express the 3′ ORF.

Derivation of names

Nyfulva: from the type species Nylanderia fulva virus 1.

Species demarcation criteria

Formal species demarcation criteria have not yet been established. ORF1-encoding amino acid sequence identity between isolates and strains of a species is above 90%.
