Genus: Erbovirus
Family: Picornaviridae
Genus: Erbovirus
Distinguishing features
The genus is distinguished on the basis of genetic characters. The 2B and 3C proteins of erboviruses have exceptionally large chain lengths (283 and 251 aa, respectively).

Genus: Dicipivirus
Family: Picornaviridae
Genus: Dicipivirus
Distinguishing features
In contrast to other picornaviruses, the genome layout of dicipiviruses exhibits two ORFs separated by an intergenic region (IGR) that functions as an IRES to translate the second ORF. The IGR-IRES shows no similarity to the equivalent region in members of the Dicistroviridae.
