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

Species within the genus Cinctura include:

• Cinctura branhamae (Rehder & Abbott, 1951)
• Cinctura hunteria (Perry, 1811)
• Cinctura lilium (Fischer von Waldheim, 1807)

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.^[4]

Evolution

Cinctura is closely related to Fasciolaria.^[5] The earliest known fossils of Cinctura date to the Piacenzian age of the Pliocene.^[6]

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.^[7]
