Family: Hypoviridae

Genus: Deltahypovirus

Distinguishing features

Viruses of this genus are distinguished from other hypoviruses based on polyprotein-derived phylogenetic trees.

Virion

Not reported

Genome organization and replication

In general, monocistronic, positive-sense RNA genomes of 8.9 kb to 9.9 kb.

Biology

Found in association with invertebrate animals, but experimental host assignment is still lacking.

Species demarcation criteria

Members of different species are distinguished by the arbitrary threshold of less than 80% amino acid sequence identity in the whole RdRP-containing polyproteins.
