Closely related to S. nigricollis and S. luctuosa#R; visual similarity to S. albogularis (although differing in bill and throat colour) not an indication of relationship. Race hellmayri formerly known as ornata, but that name invalid, as preoccupied. Three subspecies recognized.

  • S. c. caerulescens (Vieillot, 1823) – SE & E Bolivia, SC & SE Brazil S through Paraguay, Argentina (S to Mendoza and La Pampa) and Uruguay; S populations migrate N to E Peru and across much of C Brazil#R.
  • S. c. hellmayri Wolters, 1939 – S Bahia, in E Brazil.
