Kappaarterivirus wobum is the only species in the family. There is, however, considerable variability between available wobbly possum disease virus (WPDV) sequences isolated in New Zealand and Australia (70 to 80% identity at the amino acid level within the conserved RNA-directed RNA polymerase (RdRp) protein) and hence, these may be split into separate species in the future.
Members of this genus form a clade upon phylogenetic analysis (Figure 3. Arteriviridae).
See discussion under family description.
Members of this genus infect mice and typically cause lifelong persistent infections without obvious symptoms. One isolate of lactate dehydrogenase-elevating virus (LDV C) has been associated with neurological disease in the C58 mouse strain.
See discussion under family description.
Betaarteriviruses infect pigs

Members of this subfamily form a clade upon phylogenetic analysis (Figure 3. Arteriviridae). They encode an nsp2 protein that is considerably larger than its counterparts in viruses of other subfamilies, mostly due to the hypervariable region flanked by PLP2 and TM1.
Kibale red colobus virus 1 (KRCV-1), a member of the only species in this genus. KRCV-1 infects Red colobus monkeys in Kibale National Park, Uganda, subclinically and persistently with high viral loads in the blood.
See discussion under family description.
Mikumi yellow baboon virus 1 (MYBV-1) and Kafue kinda chacma baboon virus (KKCBV) infect wild baboons (genus Papio) subclinically.
See discussion under family description.
Kibale red-tailed guenon virus 1 (KRTGV-1), DeBrazza’s monkey arterivirus (DeMAV), Pebjah virus (PBJV) infect Old World cercopithecine primates and cause hemorrhagic disease in captive macaques and subclinical infection in wild African primates of the genus Cercopithecus (KRTGV-1, DeMAV).
The single known member of this genus Kibale red colobus virus 2 (KRCV-2) infects red colobus monkeys.
See discussion under family description.
