Species are placed in the genus based upon phylogeny and host range.
Non-segmented, negative-sense RNA.
Berhavirus genomes encode up to 5 proteins including a putative nucleocapsid protein, glycoprotein and RNA-directed RNA polymerase identified on the basis of sequence similarity and structural properties shared with mononegavirus homologues, in addition to one or more hypothetical proteins of unknown function.
Berhaviruses have negative-sense RNA genomes of 9.4–10.7 kb (Shi et al., 2016).
Berhavirus genome sequences were isolated from invertebrate marine animals including echinoderms and sipunculids (marine worms).
Due to the small number of genus members, no firm species demarcation criteria have been established beyond phylogeny and the hosts the viruses infect.
Berhavirus: from Běihǎi rhabdo-like virus 3 and virus the suffix for a genus
