==Taxonomy== Eleven named species are within the genus Pegivirus. Isolates belonging to the species Pegivirus C are monophyletic and show 50% nucleotide (>55% amino acid) divergence from other members of this genus. Pegiviruses assigned to this species (Pegivirus A) originate from primate host species (humans, chimpanzees and several New World monkey species). The sequence U22303 has been assigned as the type member of the species, as this was the first pegivirus to be described for this species. Terminology to describe viruses with different hosts has not been approved by the International Committee on Taxonomy of Viruses; however, Pegivirus A viruses have been called HPgV for human pegivirus, SPgV for new world simian pegiviruses, and SPgVcpz for chimpanzee simian virus.
