Book: Jingchuvirales
Family: Aliusviridae
Genus: Obscuruvirus
Distinguishing features
Obscuruviruses are currently distinguished from viruses of the second genus in the family based on the basis that their L protein sequences are < 31% identical.
Biology
The only classified obscuruvirus, Atrato chu-like virus 5 (AClV5), has been associated with dipteran insects, i.e., culicid mosquitos (Psorophora albipes (Theobald, 1907)) in Colombia (unpublished, GenBank accession MN661033). Unclassified obscuruviruses have also been associated with bivalves and mosquitoes (Truong Nguyen et al., 2022).
Species demarcation criteria
Members of different species have L protein sequences with <90% amino-acid identity (Di Paola et al., 2022).
