The genus comprises species whose members have virion particles of 1,500 to 1,700 nm in length, a positive-sense, single-stranded RNA genome of 16–16.9 kb, and no known insect vector.
See discussion under family description.
The genus comprises species whose members are transmitted by whiteflies. Virions are 650–900 nm long and have a bipartite genome, but potato yellow vein virus (PYVV) has a tripartite genome.
See discussion under family description.
The genus comprises species whose members have virions that are 1,400–2,000 nm long, a monopartite genome of 13.0–18.5 kb, and are transmitted by pseudococcid mealybugs and soft scale insects.
See discussion under family description.
Members of the genus have particle lengths > 1,200 nm and a single-stranded monopartite RNA genome of 14.5–19.3 kb, in which the minor coat protein (CPm) gene is located upstream of the coat protein (CP) gene. Transmission is by aphids.

Viruses in this genus form a distinct clade within the family Caliciviridae (Figure 4. Caliciviridae). ORF2 encodes the major capsid protein that is translated as a larger precursor protein before cleavage into the mature VP1, a feature that appears unique to this genus.
