Cinctura Explained

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 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.

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.
