The valid name of the Curl-crested Aracari (Pteroglossus beauharnaesii)

Abstract

ABSTRACT Under the International Code of Zoological Nomenclature, the valid form and source of the name for the well-known Curl-crested Aracari should remain Pteroglossus beauharnaesii Wagler, 1832. Although it is an incorrect subsequent spelling, its challenger, Pteroglossus beauharnaisii, is a nomen oblitum. Pteroglossus beauharnaesii Wagler, 1832 has been in universal use since 1900, and it is protected either by Article 23.9 or 33.3.1 of the Code, depending on the interpretation of the way the younger name was introduced.
