Subspecies
Distinctive bush-warbler with no known close relatives. Has been suggested as being nearest to Friendly Grasshopper-warbler (Locustella accentor), but that species has boldly spotted underparts and lacks supercilium, so that similarity rather limited. Subspecies musculus poorly known, and distinction from disturbans based on only two or three specimens and a larger sample of material may show it to be invalid.

The following 3 subspecies are recognised:

castanea (B�ttikofer, 1893) - Mountains of Sulawesi.
disturbans (Hartert, 1900) - Buru, in southern Moluccas.
musculus (Stresemann, 1914) - Seram, in southern Moluccas.
