lower part of valley of Igriva River, where it flows into Aniva Bay, Tonino-Anivsky Peninsula, southern Sakhalin.
Although described as a species, usually treated as a race of L. fasciolata, but genetic distinctiveness rather strong#R#R#R; and while it differs only subtly in morphology, with summer birds having browner, less olive-green upperparts (1), brown vs grey ear-coverts (ns), reduced or no grey on dull olive-buff breast and flanks (1), warm fulvous-brown vs pale brown lower flanks to vent (1) and slightly shorter wing and tarsus (allow 1), vocally fairly distinctive, with slower (2), longer (2) song phrases#R. However, review of characters suggests distinctiveness of plumage characters not always consistent#R#R, and trend in L. fasciolata in NE China towards characters associated with present species#R indicates more work is needed to confirm this split. Monotypic.
Sakhalin, S Kuril Is and N Japan (Hokkaido); non-breeding range presumably in the Wallacean region.
