One of the so-called “croaking group” of toucans (see R. toco), along with three species usually considered conspecific with it, namely R. culminatus, R. vitellinus and R. ariel, because of extensive hybrid populations which render it difficult to draw strict boundaries separating forms geographically. Nevertheless, present species differs from R. culminatus (with which it groups morphologically against R. vitellinus and R. ariel; which see) in its lemon-yellow (vs white) breast (3); greenish-yellow (vs yellow) culmen (ns); differently coloured bill base, replacing yellow (upper) and blue (lower) with blue on both mandibles shading to yellow and red adjacent to feathers of face (2); paler yellow rump (ns); and iris dark blue (vs brown)#R (1, possibly 2); also, broad hybrid zone (1). Monotypic.
