Usually considered conspecific with S. torqueola, but differs in its double white wingbars (3); all-grey or white-edged grey vs broad cinnamon rump (3); either broad black breastband or no breastband vs narrow black breastband (2); paler (whitish to whitish-buff) underparts (ns[1]). Separation of race sharpei proposed#R, but this form highly variable, with many intermediates with nominate. Three subspecies recognized.
