J. F. Gmelin, 1789,
Guiana = “Cayenne”.
Closely related to S. maranonica and S. albilora (with simoni; see below), and often treated as conspecific; DNA data#R show that these taxa form a monophyletic group. S races of present species, which vary clinally stepwise, are vocally closer to S. albilora#R and become more like it in plumage as ranges approach each other. Thorough analysis of species limits required. Boundaries of some races uncertain, inornata intergrading with certhiola in Beni Valley (Bolivia), and birds from lower R Purus E to lower R Madeira (Brazil) apparently intermediate between inornata and nominate; rigorous analysis may reveal widespread clinal variation. Six subspecies currently recognized.
