'''''Tomopleura striata''''' is an extinct species of sea snail, a marine gastropod mollusk in the family Borsoniidae.<ref name="WoRMS">Marshall, B. (2015). Tomopleura striata. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=831667 on 2016-04-04</ref>

==Description== (Original description) The shell is of moderate size, measuring 20&nbsp;mm in height and 11&nbsp;mm in maximum diameter. The spire consists of four whorls, each possessing a prominent carina near its posterior margin, which imparts a distinctly turreted morphology to the shell. Each whorl is ornamented with strong spiral cords. The penultimate whorl displays seven such cords posterior to the carina and three smaller ones anterior to it. The number of cords decreases on the apical whorls, with the protoconch appearing nearly smooth. The intersection of well-developed growth lines and the spiral cords gives them a slightly tuberculate appearance. The pronounced carina and spiral ornamentation on the body whorl serve as key diagnostic features distinguishing this species from other New Zealand Turridae.<ref>{{cite journal |last1=Marshall |first1=P. |title=The Wangaloa beds. |journal=Transactions and Proceedings of the New Zealand Institute |date=1917 |volume=49 |page=457 |url=https://www.biodiversitylibrary.org/page/3313452 |access-date=26 August 2025}} {{PD-notice}}</ref>
