Other common names: Grey-throated Leafscraper
Taxonomy: Sclerurus albigularis P. L. Sclater and Salvin, 1868, Cumbre de Valencia, Carabobo, Venezuela.
Plumage similarities and biogeography suggest that S. scansor may be its sister-species. Pattern of geographical variation generally conforms to Gloger’s Rule, with plumage darker in warm, humid areas than in colder, drier ones. Within nominate race, population in Trinidad and Tobago significantly smaller than mainland populations. Racial identity of birds from SW Brazil (Acre, N Rondônia) and others reported from S Bolivia (Tarija) uncertain; presumed to belong to albicollis.

Plumage similarities and biogeography suggest that S. scansor may be its sister-species. Pattern of geographical variation generally conforms to Gloger’s Rule, with plumage darker in warm, humid areas than in colder, drier ones. Within nominate race, population in Trinidad and Tobago significantly smaller than mainland populations. Racial identity of birds from SW Brazil (Acre, N Rondônia) and others reported from S Bolivia (Tarija) uncertain; presumed to belong to albicollis. Proposed race kunanensis, of Perijá Mts (Colombia-Venezuela border), described as having belly more greenish-olive, remiges more olivaceous and rectrices blackish, but appears indistinguishable from nominate. Six subspecies recognized.
