Part of the P. discurus clade (see below). Was previously thought possibly to belong to a group containing P. waterstradti, P. montanus and P. platenae. Sometimes still treated as conspecific with P. montanus, but case recently made for species status#R#R. Monotypic.


Sulu Archipelago, in SW Philippines. Possibly persists only on Tawitawi; at least historically, found also on smaller islands of Tumindao (no recent records), Sibutu, Manuk Manka (no recent records), Bongao (considered probably extinct) and Sanga-Sanga (probably extinct).
