''. Plants serve as natural hosts. The genus has two species.
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
* ''Citrivirus citri'',
Citrus leaf blotch virus
* ''Citrivirus unipolysciasii'',
Polyscias citrivirus 1
Structure
Viruses in ''Citrivirus'' are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm, with a length of 960 nm. Genomes are linear, around 8.7kb in length. The genome has 3 open reading frames.

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Plants serve as the natural host.[
