Members of this genus infect horses or donkeys. Infections range from asymptomatic to severe. The equine arteritis virus genome is the shortest in the family.
See discussion under family description.
Members of this subfamily form a clade upon phylogenetic analysis (Figure 3. Arteriviridae). PLP1a is enzymatically inactive and, as a result, only a single nsp1 is produced in cells infected with equine arteritis virus. EAV also does not have nsp2TF or nsp2N ORFs produced by ribosomal frameshifting.
The virus Olivier's shrew virus 1, a member of the only virus species in the genus, was isolated from Olivier’s shrews in Guinea.

There is only one genus in the subfamily. See “Subfamily, genus and species demarcation criteria” on the family page for genus demarcation criteria which are universal for all subfamilies.
