'''''Dibaphimitra''''' is a genus of sea snails, marine gastropod mollusks in the family Mitridae.<ref name="WoRMS">{{WRMS species|415292|''Dibaphimitra'' ||9 September 2025}}</ref> First described in 1970 by Walter Oliver Cernohorsky, the genus has a single extant member, ''Dibaphimitra florida'', found in the Caribbean Sea. One fossil taxon, is also included in ''Dibaphimitra'', ''D. dennanti''.
==Description==
''Dibaphimitra'' measure between {{cvt|25-80|mm}} in size, and have an inflated final whorl. Members of the genus have a teleoconch with 4–6 convex whorls, and a protoconch of 1.5–3.5 smooth whorls. The aperture is longer than its spire. The animal is colored milky white with brown irregular blotches.<ref name="OriginalDescription"/>
==Taxonomy==
The taxon was first described as the subgenus ''Mitra (Dibaphimitra)'' in 1970 by New Zealand malacologist Walter Oliver Cernohorsky, who assigned ''Dibaphimitra florida'' (then ''Mitra florida'') as the type species.<ref name="OriginalDescription">{{cite Q|Q115112302|pp=37}}</ref> Since publication, ''Dibaphimitra'' has been elevated to genus level.
There are two members of the genus, the extant ''Dibaphimitra florida'', which was added to the taxon by Cernohorsky in 1970,<ref name="OriginalDescription"/> and ''Dibaphimitra dennanti'' (formerly known as ''Mitra dennanti'' and ''Volutomitra dennanti''), a fossil species known from the Muddy Creek Formation of the Otway Basin in Australia.<ref name="Darragh">{{cite journal|title=A checklist of Australian marine Cenozoic Mollusca |first1=Thomas A. |last1=Darragh |journal=Memoirs of Museum Victoria |date=2024 |volume=83 |page=37-206}}</ref> ''Dibaphimitra janetae'', described by Edward James Petuch in 1987,<ref>{{cite book|last=Petuch |first=E. J. |year=1987 |title=New Caribbean molluscan faunas. |location=Charlottesville, Virginia |publisher=The Coastal Education and Research Foundation |isbn=0938415018 |pp=70}}</ref> was synonymised with ''D. florida'' in 2004.<ref>{{cite book|first1=Alain |last1=Robin |first2=Jean-Claude |last2=Martin |year=2004 |title=Mitridae Costellariidae |location=Paris |publisher=Xenophora |isbn=978-3925919664 |pp=17}}</ref>
As of 2018, the genus has not been ascribed to a subfamily within Mitridae.<ref>{{cite Q|Q104454683}}</ref>
==Distribution==
While living members of genus are found in the Caribbean Sea, fossil shells of the genus have been found since the Miocene in a much wider area,<ref name="OriginalDescription"/> including Australia.<ref name="Darragh"/>
