Hitherto treated as conspecific with T. bernardi and placed in Sakesphorus (see T. bernardi), but differs in its smaller size, notably shorter tail (effect size −3.3; score 2); buff-tinged whitish vs pale tan-buff underparts in female (2); much reduced black breast patch in male, so that malar and ear-coverts are black-speckled whitish rather than black or blackish (2); darker, less rufous dorsal coloration in male (1); and faster song, with greater pace (2) and shorter note length (2)#R. Monotypic.
