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 Cinctura was originally proposed as a subgenus of Fasciolaria in 1957 by Solomon Cady Hollister. It was raised to the rank of genus by Snyder et al. in 2012. Cinctura are known as "banded tulip shells"
Species Species within the genus Cinctura include: Cinctura branhamae (Rehder & Abbott, 1951) Cinctura connori Petuch & Berschauer, 2020 Cinctura hunteria (Perry, 1811) Cinctura keatonorum Petuch, 2013 Cinctura lilium (Fischer von Waldheim, 1807) Cinctura salasi Petuch & Berschauer, 2023 Cinctura tortugana (Hollister, 1957)
Identification 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.
Evolution Cinctura is closely related to Fasciolaria. The earliest known fossils of Cinctura date to the Piacenzian age of the Pliocene.
Range 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.
