See comments by Peterson on Zoonomen website (posted 2007, accessed 2015): 'It appears to me that the systematic problem with this species is great, and resolution of the nomenclatural issues must await progress on the systematic front. The Gould xanthornus name may well be the appropriate one for this population, but only if manimbe Lichtenstein is shown to be a synonym of humeralis Bosc, and not a senior synonym of xanthornis Gould'
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
U.S. Fish and Wildlife Service.
