M. H. C. Lichtenstein, 1823,
Molecular data indicate that R. brevis is sister of present species#R. Both belong to the so-called “croaking group” of toucans (see R. toco), along with three species usually considered conspecific with it, namely R. citreolaemus, R. culminatus and R. ariel, because of extensive hybrid populations which render it difficult to draw strict boundaries separating forms geographically. Nevertheless, irrespective of degree of hybridization (which in any case would here add to scores), present species (with R. ariel) is strongly distinct from R. citreolaemus (with R. culminatus) on account of its red vs yellow rump (3), orange vs white or lemon breast (2), broad vs narrow red bellyband (2), and shorter bill with black vs yellow or yellow-green culmen (3); it is strongly distinct from R. ariel by virtue of characters indicated under that species (see below). Previously described forms berliozi (R Negro, in N Brazil) and osculans (upper R Negro) are crosses between vitellinus and culminatus. Monotypic.
