Pacheco & Whitney (2006) suggested that the name Ramphastos piperivorus Linnaeus, 1766, had priority over Pteroglossus Culik Wagler, 1827 [= Selenidera culik (Wagler, 1827)] for the Guianan Toucanet. This proposal was challenged by Walters (2007), who drew attention to the paper by Peters (1930) to which Pacheco & Whitney had made no reference.
