Family: Lispiviridae

Genus: Copasivirus

Distinguishing features

Members of the genus Copasivirus are distinguished from members of other genera by their branching on phylogenetic tree constructed with the L-INS-i algorithm and inferred using ModelTest-NG and the LG substitution model, and by having an RNA-directed RNA polymerase (RdRP) domain amino acid sequence that is less than 70% identical to that of members of other genera in the family.

Species demarcation criteria

Members of different species in the genus Copasivirus are <85% identical in RdRP domain amino acid sequence.
