A shy and elusive bird, the mountain peacock-pheasant is distributed and endemic to montane forests of the central Malay Peninsula.
The molecular data suggests - though not with high confidence - that this species diverged from mainland stock earlier than the bronze-tailed peacock-pheasant.
What seems clear is that the present species evolved from mainland Southeast Asian stock, probably during the Late Pliocene to Early Pleistocene (3.6-1 myr[2]).
The unique pattern of wings and tail thus is, contrary to long-held opinion, an autapomorphy, and the southern species of this clade - formerly separated in the genus Chalcurus - are probably not each other's closest relatives.
Due to ongoing habitat loss, small population size and limited range, the mountain peacock-pheasant is evaluated as Vulnerable on the IUCN Red List of Threatened Species.
