Salvin and Godman, 1883,
Bartica Grove, Guyana.
Formerly treated as a full species, but in recent years lumped with Z. gracilipes until molecular analysis#R corroborated separation. Differs from gracilipes in its almost pure white face and lower throat (1); paler yellow underparts (1); and notes (one or two) of daytime call (falling “chu-chup” or “chup” vs rising “wheet” or “whit”) being very short (ns), decreasing in pitch (3), with higher maximum frequency (2) and very different shape (ns)#R. Populations on N side of Amazon give “chu-chup” call, those on S side give “chup”, suggesting presence in latter of an unnamed taxon. Monotypic.
