. . "The Phasianinae (Horsfield, 1821) are a subfamily of the pheasant family (Phasianidae) of landfowl, the order Galliformes. The subfamily includes pheasants, tragopans, junglefowl, peafowl, and other similar birds. Although this subfamily was considered monophyletic and separated from the partridges, francolins, and Old World quails (Perdicinae) till the early 1990', molecular phylogenies have shown that this two subfamilies actually constitute only one lineage."@en .
