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: Fenneropenaeus chinensis hepatopancreatic densovirus (Hepanhamaparvovirus decapod1). [5] [6]
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]
