The Guianan toucanet was originally described as belonging to the genus Pteroglossus. Recently, some discussion was made of the naming of this species. Pacheco & Whitney (2006) suggested the correct scientific name was Selenidera piperivora, but then Walters (2007) noted that this name was pre-occupied.
The spot-billed toucanet (Selenidera maculirostris) is a species of bird in the toucan family Ramphastidae.

The toco toucan (Ramphastos toco), also known as the common toucan, giant toucan or simply toucan, is the largest and probably the best known species in the toucan family. It is found in semi-open habitats throughout a large part of central and eastern South America. It is a common attraction in zoos.
