Edwards's Pheasant

Taxonomy
Was formerly placed in the genus Delacourigallus and Hierophasis, but genetic studies found that no evidence that Lophura as currently constituted is polyphyletic; the same study showed that Lophura comprises of five clades, of which L. edwardsi forms a clade with L. swinhoii.

Form known as “Imperial Pheasant, L. imperialis” now known to be a hybrid between L. edwardsi and L. nycthemera. Form hatinhensis, sometimes treated as a full species, L. hatinhensis or as a subspecies of L. edwardsi, now judged to be an unstable variant produced by inbreeding.

Edwards's Pheasant includes Vietnamese Pheasant (L. hatinhensis). Its taxonomic status is uncertain, but species description inadequate and hypotheses re variation in Edwards's Pheasant unresolved.
