Dibaphimitra is a genus of sea snails, marine gastropod mollusks in the family Mitridae.[1] 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
[edit | edit source]Dibaphimitra measure between 25–80 mm (0.98–3.15 in) 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.[2]
Taxonomy
[edit | edit source]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.[2] 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,[2] 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.[3] Dibaphimitra janetae, described by Edward James Petuch in 1987,[4] was synonymised with D. florida in 2004.[5]
As of 2018, the genus has not been ascribed to a subfamily within Mitridae.[6]
Distribution
[edit | edit source]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,[2] including Australia.[3]
Species
[edit | edit source]Species within the genus Dibaphimitra include:
- Dibaphimitra dennanti (Tate, 1889) †[7]
- Dibaphimitra florida (Gould, 1856)[8]
