Until recently considered conspecific with S. longirostris, but differs in having strongly divergent voice (a short flat-toned but rising penetrating whistle vs various versions of a similar-length whistle rather abruptly modulated in the pattern up-down-up “iiiiui”#R)(3); larger size than neighbour ruficervix (and discounting southernmost patagonica) (at least 1); overall darker plumage, with darker brownish markings on rump, tertials, wing-coverts and tail-coverts (1); fewer and smaller white markings on upperparts, breast and wing, latter with white markings on P7–10 not forming unbroken bar, and with ochraceous-buff vs white at carpal joint (2). Genetic data indicate that present species is sister to S. longirostris ruficervix, and that together these two form a clade that is sister to the rest of the taxa formerly placed in S. longirostris, excluding S. decussata#R, which is also treated specifically here. Monotypic.
