Subspecies
No subspecies.

Morphology and voice suggest that this species' closest affinites are probably with Western Crowned Leaf-Warbler (Phylloscopus occipitalis). Was in the past sometimes considered to be a subspecies of Eastern Crowned Leaf-Warbler (Phylloscopus coronatus), or a derivative island subspecies of Pale-legged Leaf-Warbler (Phylloscopus tenellipes), but nesting preferences, vocalizations and DNA all indicate that it is a separate species.

Similar Species
Arctic Warbler (Phylloscopus borealis) which is larger, stockier, has yellowish supercilium, cheeks and underparts.
