Long treated as a race of K. aterrimus, even recently, despite contrary evidence#R, but now found to belong in a distant clade#R. Differs from K. aterrimus in its red vs dark brown iris (3); shorter bill (on published data#R male effect size vs next closest taxon, K. a. aterrimus, −2.9, score 2) and tarsus, although wing and tail of similar lengths; in male, silvery-black vs pale bluish bill (2); in female, heavy dark streaking vs, at most, light streaking on breast (ns[2]), and tail almost all-black (narrow white outer margins) vs black and cinnamon (3). Monotypic.

Distribution:

CE Brazil, from São Francisco Valley in SW Bahia and N & C Minas Gerais W to SE Tocantins (Serra Geral), NE Goiás and Distrito Federal.
