Jatubá, western Goiás.
Until recently considered conspecific with T. nigriceps, but HBW text mistaken in suggesting distinctions “relatively minor” (and molecular study places the two taxa far apart#R): differs in its white vs pale grey to whitish-grey mid-breast to vent (3); more white in streaked throat pattern, with small white crescent on uppermost breast (2); crown concolorous with upperparts rather than distinctly darker (ns); female much more like male, without brown tones of female T. nigriceps (2); slightly smaller bill (effect size –1.11, score 1) but rather longer tail (effect size 2.01, score 2); and very different song (a repetition of some four similar-sounding dissonant notes, often preceded by a high-pitched descending whistle, vs some jumbled medium-pitched whistles gradually shifting towards high-pitched “see” notes), involving much shorter song phrase (3) with fewer different notes (3) and no clear difference in pitch between start and finish (ns)#R. Monotypic.
E Paraguay, SE Brazil and NE Argentina (Misiones); non-breeding also N to SC Brazil (N to Mato Grosso and Goiás).
