E. Snethlage, 1925,
Acajutuba, lower Rio Negro, Brazil.
Close to H. perrotii and possibly conspecific, having similarities in voice and morphology; characters of race insignis suggest possible intergradation between the two species. Has apparently hybridized intergenerically with Dendrocolaptes picumnus in W Brazil, one of few cases of hybridization in suboscines. Three subspecies recognized.
