Comments: Molecular data (Rowe and Honeycutt, 2002) clearly support the inclusion of Hydrochoeris within the Caviidae. Kerodon is included due to the consistently observed sister taxon relationship between Hydrochoerus and Kerodon (dos Reis, 1994; Rowe and Honeycutt, 2002; Woods, 1984). Several distinct linages of the Hydrochoerinae are known in the fossil record and some fossil forms extend into North America during the late Pliocene and Pleistocene (Mones, 1984)
According to McKenna & Bell (1997:202), the family-group name is based on Hydrocharina Gray 1825:341. Gill (1872) established the spelling Hydrochoeridae, and Cabrera (1961) changed it to Hydrochaeridae. Note also that that the generic name Hydrochoerus Brisson 1762 has been restored by ICZN Opinion 1894 (1998)
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
