Until recently considered conspecific with T. flavotectus (see below). Race sucunduri newly described as species#R, most closely related to races assimilis, calamae and paraensis, differing in its darker and more uniformly lead-grey crown (1); slightly darker green back (1); more widely modulated notes in loudsong (2)#R; and hybrid zone with assimilis/calamae in S of range (zone presumed narrow; 2); thus, on current evidence, it falls just short of species status, although new study may validate it. Other races show subtle variations in crown, breast and belly colours (breast becoming slightly darker in anticlockwise direction from the Guianas and NE Brazil back towards E Brazil S of Amazon; crown colour shows similar but slightly discordant pattern); further study needed on taxonomic limits within these races, including vocalizations, as songs of neglectus and examinatus N of Amazon are relatively distinctive vs those of taxa S of Amazon. Eight subspecies recognized.
