Small tanager known only from Cerros del Sira, a remote ridge east of the main chain of the Andes in central Peru. Male has a turquoise throat surrounded by black coloration extending to the crown and belly; the back, wings, and sides are light blue. Female is pale greenish with a gray crown, a bluish tinge on the throat, and a grizzled appearance to the head and neck. Both sexes can be told from Silvery Tanager by the blue (not copper-colored) throat. Female is similar to female Green-throated Tanager, but has a gray crown and lacks bright yellow on back and sides. Inhabits scrub and stunted cloud forest.
