Hepanhamaparvovirus is a genus of viruses that belongs to the Hapanhamavirinae subfamily[1] of the family Parvoviridae.[2][3] Insects and shrimps serve as natural hosts. Infection leads to mortality in the early larval and postlarval stages of the shrimp.[4][1] There is only one species in this genus: Decapod hepanhamaparvovirus 1.[5]
Viruses in genus Hepanhamaparvovirus are non-enveloped, with T=1 icosahedral symmetry and round geometries. The diameter is around 21-22 nm. Genomes are linear, around 6kb in length.[4][3]

Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediate clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export. Insects and shrimps serve as the natural host.[4][3]
