New Zealand Recent Trochini are revised, illustrated and keyed. Eleven species are recognised, including four new species of Thoristella . A new subgenus of Trochus is introduced for Trochus camelophorus Webster, 1906. The following taxa are newly synonymised with Thoristella chathamensis (Hutton, 1873): Trochus oppressus dunedinensis Suter, 1897, Calliostoma aucklandicum E.A. Smith, 1902 and Thoristella chathamensis cookiana Powell, 1934. Trochus carmesina Webster, 1908 is transferred from Talopena to Thoristella , and Thoristella fossilis Finlay, 1926 is transferred to Trochus (Coelotrochus). Lectotypes are designated for Trochus tiaratus Quoy and Gaimard, 1834, Trochus viridis Gmelin, 1791, Polydonta viridescens A. Adams, 1853, Polydonta elegans Gray, 1835, Polydonta tuberculata Gray, 1843, Trochus fulvolabris Hombron and Jacquinot, 1854, and Calliostoma aucklandicum E.A. Smith, 1902.
