Treated as conspecific with T. longirostris until split in HBW; there it retained T. mysticalis as a subspecies, but latter now separated in recent review of complex#R. Differs from T. mysticalis, T. lucasi, T. aurea and T. platenae in characters given under those species. From T. longirostris in its rather smaller size and notably shorter tail (effect size for latter –4.82; 2); half-wedge yellow vs olive-green lores (2); darker, more extensive olive-green breast (2); and different tail pattern, with broad yellow tips and all-yellow undersides vs broad yellow edges on both surfaces (3). From T. chloris in its greater size (effect size for bill length 4.68; 2); half-wedge yellow lores vs all olive-green lores (2); yellow tips on uppertail-coverts (1); and rectrices broadly tipped and edged yellow (entire undertail bright yellow) vs olive-green (3). Various vocal differences apparent from recent published descriptions#R. Two subspecies recognized.
