Sister to S. castanea, based on genetic data#R; both probably also close to S. fuscorufa, and the three have been considered conspecific, but substantial vocal differences exist. Song of each race fairly distinctive, suggesting possible species-level differences#R, e.g. meridana differs from all others in its series of almost identical notes resulting in a length ratio of 1.06–1.4 (score 3) and on average highest number of notes (score 1), and from nominate and ochrogaster also in smaller frequency range (score 1 or 2); munoztebari differs from nominate/ochrogaster in shorter “long notes” resulting in smaller length ratio (score 2), a higher number of notes (ns[1]) and a smaller frequency range (score 1 or 2); ochrogaster differs from nominate in song having fewer notes (score 1) and a more disyllabic long note, also in having an alternative vocalization (score 1 or 2). Plumages, however, often very similar; proposal#R#R#R that munoztebari may merit species rank not well supported by specimen evidence, but further study needed. Birds in Cajamarca (N Peru), duller and less rufous than any others, apparently represent an undescribed race. Four subspecies recognized.
