Until recently considered conspecific with P. chloronotus (itself formerly treated as conspecific with P. proregulus), but differs genetically#R and in its darker, less brownish colour above (1); more sulphur-yellow rump (1); black vs pale base of lower mandible (1); song, with a wider frequency range (2) and slower delivery (2) in both types; and call being an unvarying “tsuist” vs a shorter “psit” (ns[2])#R. Monotypic.
