Rio Ilhéus, Bahia, Brazil.
Until recently considered conspecific with T. velia (which see), but separated as a phylogenetic species#R; in fact, differs in its pale silvery-blue vs deep blue underparts (3); broad pale yellow bar across forehead vs very narrow indistinct such bar in T. v. signata, none in other taxa (2); deep blue carpal patch and edges of wing-coverts vs turquoise in T. v. velia (2) or turquoise fringes of flight-feathers vs deep blue in T. v. iridina and T. v. signata (2); longer bill (effect size 2.46 vs T. v. velia, 3.72 vs T. v. iridina and 3.25 vs T. v. signata, although n=7 in last case; score 2); but voice apparently identical#R. Species name sometimes erroneously emended to cyanomelaena but cyanomelas, ending in a Greek word, is deemed indeclinable by ICZN Code#R. Monotypic.
