Vince S. Smith (personal communication, April 2004) notes that while there is ongoing controversy surrounding the status of human head and body lice (Pediculus humanus capitis De Geer 1778 & Pediculus humanus humanus Linnaeus 1758, respectively), there is a lot of evidence to say that they are not genetically separable. He suggests that they be treated as a single undivided species, rather than as two distinct species or subspecies
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
