Type species of Idioptilon. In past, along with H. spodiops (which see), H. griseipectus, H. orbitatus, H. iohannis, H. striaticollis, H. nidipendulus, H. margaritaceiventer, H. inornatus, H. granadensis, H. mirandae and H. rufigularis, placed in Euscarthmornis; all subsequently moved (with addition of H. kaempferi) to Idioptilon, when error in priority detected#R, and later lumped into Hemitriccus#R. Present species long treated as conspecific with H. griseipectus, but the two show major differences in plumage and voice; race naumburgae, formerly assigned to present species, belongs with H. griseipectus. E Amazonian populations, giving rattled trill of 19–38 notes, vocally very distinct from those W of R Branco and R Negro, giving call of 5–15 notes (score 3) at higher frequency (2), suggesting that two species may be involved#R; birds from French Guiana described as race rothschildi, and that name would be available for E form; clarification of morphological differences needed. Boundary between nominate race and flaviviridis uncertain, as vocal type of former occurs only E of R Branco and R Negro, in N Brazil, and that of latter extends E to those rivers; some authors propose merging the two races. Two subspecies recognized.
