Brevipenbrevirus is a genus of viruses in subfamily Penbrevirinae of the family Parvoviridae. Mosquitoes serve as natural hosts. There are four species in this genus.
Taxonomy The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
Brevipenbrevirus dipteran1, Anopheles gambiae densovirus Brevipenbrevirus dipteran2, Aedes albopictus densovirus 2 Brevipenbrevirus orthopteran1, Acheta domesticus segmented densovirus Brevipenbrevirus orthopteran2, Soybean thrips denso-like virus 1
Structure Viruses in genus Brevipenbrevirus are non-enveloped and have T=1 icosahedral symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.

Life cycle Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. Mosquitoes serve as the natural host.
