All Brazilian tanagers in the genus Thraupis have been included in the genus Tangara (which I think preceded Thraupis). I am not associated with WikiAves but it follows the nomenclature of the Brazilian Ornithological Records Committee which has adopted the new classification. That is also the case with HBW. Thus Azure-shouldered Tanager became Tangara cyanoptera and Black-headed Tanager became Tangara argentea. Hopefully somebody more knowledgeable will explain the motivations in changing from Thraupis to Tangara.
Addendum-one exception: Blue-and-Yellow Tanager, formerly Thraupis bonariensis is now Pipraeidea bonariensis.
