Sister-species to X. erythropygius#R, and sometimes regarded as conspecific; treatment as separate species supported by molecular evidence, vocalizations, apparent lack of intergradation, and elevational replacement where ranges approach (at most, very limited sympatry on W slope of Andes in SW Colombia and W Ecuador). Proposed race distinctus (W Andes of Colombia) included in nominate; hylodromus differs only slightly from nominate, but is geographically disjunct; intermedius intergrades in SE Peru with bangsi, from which it may not be reliably distinguishable. Four subspecies recognized.
