The genus is distinguished on the basis of genetic characters. Avian encephalomyelitis virus (AEV) is most similar to hepatitis A virus (HAV, genus Hepatovirus), but differs by possessing i) a type IV IRES (HAV is type III), ii) 2A with an H-box/NC motif, and iii) 2B and 3A polypeptides with little sequence identity to the HAV counterparts.

Virions are stable at acid pH. Buoyant density in CsCl is 1.33 g cm-3. Empty capsids are often observed in virus preparations.

The genus is distinguished on the basis of genetic characters. Sapeloviruses are related to enteroviruses, but possess leader polypeptides of unknown function. The 2A polypeptide may be a cysteine protease, but it is distinct from that of the enteroviruses. The 2B and 3A proteins are also very different from the enteroviruses. In both sapelovirus species the IRES is type IV, whereas in all enterovirus species it is type I.
