Viruses of this genus are distinguished from other hypoviruses based on polyprotein-derived phylogenetic trees.
Genome organization and replication
In general, monocistronic, positive-sense RNA genomes of 8.9 kb to 9.9 kb.
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.
