A. W. H. Blasius, 1888,
Formerly considered conspecific with Z. atrifrons, but re-examination of the single type specimen (previously thought to have been lost) and recent field observations indicate clear differentiation, particularly in coloration of bill and legs, measurements and some other characters; differs also in song and in being restricted to pristine habitats at higher altitudes. Monotypic.
Mt Sahendaruman and adjacent Mt Sahengbalira, on Sangihe I, N of Sulawesi.
