Aulacorhamphus (by Gould, 1940) is an unjustified emendation of Aulacorhynchus Gould, 1834. According to ICZN art. 51.3.1. 'Parentheses are not used when the species-group name was originally combined with an incorrect spelling or an emendation of the generic name (this applies even though an unjustified emendation is an available name with its own authorship and date)'
ITIS taxonomy is based on the latest scientific consensus available,
and is provided as a general reference source for interested parties.
However, it is not a legal authority for statutory or regulatory purposes.
While every effort has been made to provide the most reliable and up-to-date
information available, ultimate legal requirements with respect to species
are contained in provisions of treaties to which the United States is a
party, wildlife statutes, regulations, and any applicable notices that have
been published in the Federal Register. For further information on U.S.
legal requirements with respect to protected taxa, please contact the
