12 Introduction The genus Diptychophlia Berry, 1964 [type species Clavatula occata Hinds, 1844, by monotypy] is characterized by spire acuminate, many whorls, channeled suture, aperture narrow and anal notch shallow, open to suture. During the past decade many new genus and species of marine mollusks have been described (Simone & Cunha 2003; Pimenta & Absalão 2004; Simone & Birman 2006; Santos & Absalão 2006). Recently, J. Coltro and Dr. Paulo M. Costa, in a expedition dredging in deep waters off Fortaleza, Ceará State bringing from 280- 300 meters, collected many specimens of the several families that possibly they will contribute for the increase of new species and new occurrences for the Brazilian coast. The turrid describe herein is a part of this sample material collected in the gravel bottoms with corals dead.
