Until recently considered conspecific with S. sibilator, S. albogriseus and S. albocinereus, but detailed review#R (supplying data on which effect sizes calculated) indicates that present form differs from S. albogriseus and S. albocinerus in characters given under those species; and from S. sibilator in its less white on lower wing-coverts (1); more white on rump (1); paler breast (1); longer whistle call (effect size 4.75, score 2) and chattering song with higher maximum frequency (effect size 2.48; score 2). Monotypic.
