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]
