The species Sicinivirus ahiberni (formerly named Sicinivirus A) consists of at least eight genotypes, sicinivirus A1 to A8. There are at least four further candidate genotypes (N.J. Knowles, unpublished data). All are found in chickens.

Sicinivirus 1 was first detected in chickens in the Republic of Ireland. Sicini is the Gaelic word for chickens. Sicinivirus 1 is most closely related to passerivirus A1 having amino acid identities of 30.5%, 38.1% and 46.8% in the P1, P2 and P3 polypeptides, respectively.

The genome sequences of two picornaviruses (designated chicken picornavirus 1 by the authors) are most closely related to Sicinivirus 1 (Lau et al., 2014).
