Abstract
Two taxa belonging to the genus Onithochiton Gray, 1847 are recognised from New Zealand: O. neglectus neglectus de Rochebrune, 1881 and O. neglectus subantarcticus Suter, 1906. Chiton undulatus Quoy & Gaimard, 1835; O. astrolabei and O. filholi de Rochebrune, 1881; O. semisculptus Pilsbry, 1894; O. marmoratus von Wissel, 1904; O. nodosus Suter, 1907; O. opiniosus Iredale & Hull, 1932; and Icoplax chathamensis Dell, 1960 are synonyms of O. neglectus neglectus de Rochebrune, 1881. O. neglectus var. subantarcticus Suter, 1906 is a subspecies of O. neglectus sensu lato. O. neglectus neglectus is redescribed and a lectotype of O. neglectus neglectus is selected from de Rochebrune's syntypes, and figured. O. neglectus subantarcticus Suter, 1906 is separated from O. neglectus sensu stricto on the basis of minor, but geographically stable, differences. Onithochiton is recorded from the Bounty Islands. Onithochiton oliveri Iredale, 1914 from the Kermadec Islands is separated from the New Zealand species on girdle characters.
