THE SYSTEMATICS OF THE RADULA-LESS GASTROPOD CLATHROMANGELIA (CAENOGASTROPODA, CONOIDEA)

On the basis of foregut anatomy and embryonic/larval shell morphology, the radula-less conoidean gastropod genus Clathromangelia Monterosato , 1884 is transferred to the subfamily Daphnellinae (family Turridae). The Lower Pliocene to Recent species are reviewed. The type species i s Pleurotoma granum Philippi, 1844, Recent from Sicily. C. quadrillum Dujardin, 1837 a fossil species described from the Miocene (and rangin g to the Lower Pliocene) is here considered a distinct species, with p lanktotrophic larval development. Clathromangelia strigillata Pallary, 1904 from the Gulf of Gabes (Tunisia) is figured and redescribed. Cla thromangelia loiselieri Oberling, 1970 (lectotype here selected) is a senior synonym of C. fehrae (emend. pro C. fehri) Aartsen & Zenetou, 1 987. Three new species are described and figured from the Italian Plio cene: C. tavianii sp. n., C. elvirae sp. n. and C. marinae sp. n.
