Normally treated as conspecific with S. lunatus (previously split, when the two were thought to be sympatric), but differs in its mid-grey vs black supercilium (2); much narrower secondary bar, so that this and primary bar are not adjacent and do not form larger area of blue on wing as in other taxa (3); white subterminal spots on outer web of secondaries, forming white wing-flash (3); tips of longest primaries rounded with narrow white edges vs pointed with broad white edges (ns[3]); underparts darker, more uniform grey (ns[1]); greyer above (crown to back), with no hint of buff or rufous (all other taxa have strong wash of buff or rufous, except polionotus, which still shows trace of rufous on back and scapulars) (ns[1]). Moreover, female appears uniquely to lack white breast-line (greater sampling of taxa needed) and voice may be different#R. Monotypic.

Distribution:

NE India, Bhutan and NE Bangladesh E to W & NE Myanmar (Arakan, Chin Hills and Upper Chindwin E to R Irrawaddy).
