Misori (= Biak Island), Geelvink Bay, New Guinea.
Taxonomy unsettled; often regarded as a race of G. magnirostris#R#R#R, but seems quite distinct in having clear yellow in plumage, and confined to a long-isolated island with many other distinct endemic taxa. Reported occurrence on Biak of a gerygone (perhaps female) similar to G. palpebrosa needs to be evaluated, but is probably the same as birds allegedly similar to G. chrysogaster but with long bill; both thought likely to refer to present species. Monotypic.
