Mato Grosso, on left bank of the Rio Roosevelt in the Municipality of Colniza (09°07’54” S, 60°42’31” W) at about 150 m elevation, Brazil.
Recently described species#R, part of the “H. cantator complex” (which see). Differs from all species formerly grouped under H. cantator in stronger rufous edging on bases of rectrices (1), completely different call using 4 [3–5] notes, thus faster (3) and with more notes (3) than any other population, plus virtual or actual parapatric distribution with regard to H. ochrogyna (3). Monotypic.
