A Review of the Living Cinctura Banded Tulip Shells (Gastropoda: Fasciolariidae), with the Descriptions of Four New Subspecies and a New Subgenus

Abstract

The fasciolariid genus Cinctura Hollister, 1957, which is endemic to the Carolinian Molluscan Province, is now known to contain five distinct species: C. hunteria (Perry, 1811), C. keatonorum Petuch, 2014, C. lilium (Fischer von Waldheim, 1807), C. tortugana (Hollister, 1957), and C. branhamae (Rehder and Abbott, 1951). Four new geographical subspecies are described, C. hunteria apalachee Petuch and Berschauer, n. subsp. (Florida Panhandle to Mobile Bay), and three subspecies from deep water along the eastern edge of the Campeche Escarpment in the Yucatan Channel: C. lilium connori Petuch and Berschauer, n. subsp., C. tortugana traciae n. subsp., and C. branhamae morganae Petuch and Berschauer, n. subsp. The new subgenus Hollisteria Petuch and Berschauer, n. subgen. is proposed for the elongated, fragile deep water species of the Cinctura branhamae Complex.
