    Beu, A.G.; Maxwell, P.A. 1987 A revision of fossil and living gastropods related to Plesiotriton Fischer, 1884 (Family Cancellariidae, subfamily Plesiotritoninae n. subfam.), with an Appendix: Genera of Buccinidae Pisaniinae related to Colubraria Schumacher, 1817. Wellington: DSIR. New Zealand Geological Survey paleontological bulletin 54 140 p.

    Abstract: Genus-group taxa revised are Turehua Marwick, 1943, Plesiotriton Fischer, 1884, Africotriton n. gen., Loxotaphrus Harris, 1897, Varicohilda Eames, 1957, Tritonoharpa Dall, 1908 (= Nivitriton Iredale, 1929), and Kapuatriton n.gen. (included in the new subfamily Plesiotritoninae), and Semitriton Cossmann, 1903 and Tatara Fleming, 1950 (included in the Cancellariinae). The group is referred to Family Cancellariidae on the basis of its varices, protoconch, teleoconch form and sculpture, and the nematoglossan radulae of Africotriton crebriliratus (G.B. Sowerby III, 1903) and Plesiotriton vivus Habe & Okutani, 1981. The principal taxonomic criterion considered to unite the Subfamily Plesiotritoninae is that the axial costae are opisthocline and not collabral. Previous classifications have placed these genera in serveral other families: Fasciolariidae (Turehua), Ranellidae (= Cymatiidae) (Semitriton, Tatara, Varicohilda, some Plesiotriton species), Colubrariidae (most Plesiotriton, Africotriton and Tritonoharpa species), and Buccinidae (Loxotaphrus)
