Members of the genus Aleptorquevirus have genomes of 2.3–2.5 kb and have been identified in rabbits and hares of the Leporidae family; a virus from a mosquito may be bloodmeal-derived.
Different species in the genus have orf1 genes with <69% pairwise identity.

Similar to comovirins, cheraviruses, sadwaviruses, stralariviruses, and torradoviruses, the genome of merseviruses is bipartite. However, the RNA1 of merseviruses codes for a polyprotein that is proteolytically cleaved into six predicted proteins instead of the more conventional five proteins. The sixth protein located at the N-terminus of the polyprotein encoded by RNA1 codes a Ham1 domain with predicted inosine triphosphate pyrophosphatase (ITPase) activities.
Virus names, the choice of exemplar isolates, and virus abbreviations, are not official ICTV designations
