upper Amazon, Sarayacu (Ecuador), Colombia = “Bogotá”, Colombia.
Until recently considered conspecific with S. sibilator, S. albogriseus and S. subcanescens, but detailed review#R (supplying data on which effect sizes calculated) indicates that present form differs from S. albogriseus in characters given under that species; differs from S. subcanescens in more white on rump (2); paler throat and breast (1); shorter whistle call (effect size −3.51; score 2) and chattering song with lower maximum frequency (effect size again −3.51; score 2); and from S. sibilator in much more white on rump (3); less dorsal striation (1); less white on wing-coverts (1); longer whistle call (effect size 3.4; score 2) and chattering song with lower maximum frequency (effect size −1.42; score 1). Monotypic.
SW Venezuela (SE Portuguesa to SE Táchira), E Colombia (locally to near base of Andes from W Arauca to Putumayo), E Ecuador, E Peru, W Brazil (SW Amazonas, Acre) and N Bolivia (S to La Paz, Cochabamba and N Santa Cruz).
