Subfamily: Orthoparamyxovirinae

Genus: Narmovirus

Distinguishing features

These viruses have been isolated from rodents (Lambeth et al., 2009). All members encode a non-structural protein (C). 

Members of the genus are phylogenetically related (Figure 3. .Paramyxoviridae).

Species demarcation criteria

Species demarcation is now entirely based on the distance in the phylogenic tree based on the comparison of complete large (L) protein amino acid sequences. Since the primary criterion is the tree topology, whether a virus belongs to the same species becomes a matter of branch length between the nearest node and the tip of the branch. This length is defined as 0.03 in the trees generated as described in the legend to Figure 3. .Paramyxoviridae.
