Distinguishing features

The genus is distinguished on the basis of genetic characters. 



No details are available on the morphology of virions. 

Nucleic acid

Genome (Shi et al., 2018): c. 7,969 nt (5′-UTR: 466 nt; ORF: 7,398 nt; 3'-UTR: 105 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:


The deduced polyprotein is of 2,466 amino acids. There is an L protein with unknown function. The 1AB protein remains uncleaved. The 2A protein has an H-box/NC sequence motif. 


No virus has been isolated. Viral RNA was detected in organ pools (gut, liver, lungs) of oriental leaf-toed geckos (Hemidactylus bowringii). 

Derivation of names

Hemipivirus: derived from Hemidactylus bowringii (host) and picornavirus
