  Picornavirus genera can be phylogenetically clustered into five 'supergroups' (SG) which have now been proposed as subfamilies (Zell et al., 2021).
SG1: Proposed subfamily name: "Caphthovirinae"
Ailurivirus, Aphthovirus, Bopivirus, Cardiovirus, Cosavirus, Erbovirus, Hunnivirus, Malagasivirus, Marsupivirus, Mischivirus, Mosavirus, Mupivirus, Senecavirus, Teschovirus, Torchivirus and Tottorivirus
SG2: Proposed subfamily name: "Kodimesavirinae"
Danipivirus, Dicipivirus, Gallivirus, Hemipivirus, Kobuvirus, Livupivirus, Ludopivirus, Megrivirus, Myrropivirus, Oscivirus, Passerivirus, Pemapivirus, Poecivirus, Pygoscepivirus, Rafivirus, Rajidapivirus, Rosavirus, Sakobuvirus, Salivirus, Sicinivirus, Symapivirus and Tropivirus
SG3: Proposed subfamily name: "Ensavirinae"
Anativirus, Boosepivirus, Diresapivirus, Enterovirus, Felipivirus, Parabovirus, Rabovirus and Sapelovirus
SG4: Proposed subfamily name: "Paavivirinae"
Aalivirus, Aquamavirus, Avihepatovirus, Avisivirus, Crohivirus, Grusopivirus, Kunsagivirus, Limnipivirus, Orivirus, Parechovirus, Pasivirus, Potamipivirus and Shanbavirus
SG5: Proposed subfamily name: "Heptrevirinae"
Caecilivirus, Crahelivirus, Fipivirus, Gruhelivirus, Hepatovirus, Rohelivirus and Tremovirus
A number of other picornaviruses are not currently included in the five genus supergroups (subfamilies) but appear to form three distinct clusters (clusters 6-8).
cluster 6: Harkavirus
cluster 7: various as-yet-unassigned picornaviruses
cluster 8: Ampivirus
