Subspecies
Previously named Synallaxis rufogularis, but that name is invalid, as preoccupied. Almost certainly the sister-species of Ruddy Spinetail (Synallaxis rutilans), and type specimen was at one time considered to be an aberrant individual of subspecies amazonica of that species. Subspecies saturata often considered synonymous with napoensis, but distinguishable from latter by paler overall plumage.
The following 3 subspecies are recognised:
napoensis Gyldenstolpe, 1930 - Southern Colombia (Putumayo) and eastern Ecuador (western Sucumbíos, western Napo).
saturata Carriker, 1934 - Northern and central Peru (San Martín, Ayacucho).
cherriei Gyldenstolpe, 1930 - Central Amazonian Brazil (Rondônia, northern Mato Grosso, and southern Pará from lower R Xingu east to Serra dos Carajás).
Similar Species
Only likely to be confused with the more common Ruddy Spinetail (Synallaxis rutilans) which has a black throat patch.
