Subspecies
Formerly included Black Thrush (Turdus infuscatus) as a subspecies, but that species rather smaller and with different song and female has distinctive underwing-coverts. Birds from Argentina (Jujuy) described as subspecies unicolor, but that name invalid, as preoccupied, and no replacement proposed. Included in subspecies serranus.
The following 5 subspecies are recognised:
atrosericeus (Lafresnaye, 1848) - North-eastern Colombia and northern Venezuela.
