Members of the genus Auricularimonavirus are distinct from those of other genera by phylogenetic analysis of the RdRP gene (Figure 5.Mymonaviridae) with <32% amino acid sequence identity for the L protein. The genome is a single molecule of linear, negative-sense RNA of about 11.4 kb with six ORFs. These ORFs are separated by non-coding intergenic regions containing highly conserved gene-junction sequences. Virions, antigenicity and biology have not been reported. Virus belonging to the genus have been identified in fungi.
Species demarcation criteria
Members of different species in the genus differ by >30% in nucleoprotein amino acid sequence and by >30% in their coding-complete or complete genome nucleotide sequence.
