The members of this genus of plant viruses are similar to the Indian citrus ringspot virus. Apart from that species, only one other virus, the Citrus yellow vein clearing virus is currently recognized to belong to the genus. Both viruses only infect citrus species and are found in southern parts of Asia. The natural mode of transmission is unknown, but both viruses are graft transmissible.
