Subspecies
No subspecies.
Sometimes placed in a monotypic genus, Psamathia, but on basis of voice, egg colour and morphology now included within present genus. Together with Shade Bush-Warbler (Horornis parens) and Fiji Bush-Warbler (Horornis ruficapilla) (possibly also Tanimbar Bush-Warbler (Horornis carolinae)) probably most closely related to Japanese Bush-Warbler (Horornis diphone). These species appear to be relicts of a single, formerly more widespread species in Indo-Pacific region.
