Cinctura is a genus of fasciolariid sea snails known as the banded tulip shells. Species in this genus were previously grouped in the closely related genus Fasciolaria.
Taxonomy
[edit]Cinctura was originally proposed as a subgenus of Fasciolaria in 1957 by Solomon Cady Hollister.[1] It was raised to the rank of genus by Snyder et al. in 2012.[2] Cinctura are known as "banded tulip shells"[3]
Species
[edit]Species within the genus Cinctura include:
- Cinctura branhamae (Rehder & Abbott, 1951)
- Cinctura hunteria (Perry, 1811)
- Cinctura lilium (Fischer von Waldheim, 1807)
Identification
[edit]Cinctura differ from the closely related Fasciolaria in bearing a prominent parietal ridge within the aperture of the shell and in lacking an inflected sutural ramp.[4]
Evolution
[edit]Cinctura is closely related to Fasciolaria.[5] The earliest known fossils of Cinctura date to the Piacenzian age of the Pliocene.[6]
Range
[edit]The range of Cinctura species is restricted to the Gulf of Mexico and off the southeastern United States. No known species, living or extinct, are known from the Caribbean.[7]
