Clathurellidae


Clathurellidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.

Taxonomy

2005 taxonomy

In the Taxonomy of the Gastropoda (Bouchet & [Rocroi, 2005)|taxonomy of the Gastropoda by Bouchet & Rocroi (2005)] Clathurellinae was classified as a subfamily of Conidae.

2011 taxonomy

In 2011 Bouchet, Kantor et al. brought some genera from the subfamily Clathurellinae in a new family, Clathurellidae. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments.

Description

Species in this family have small to medium-sized fusiform shells that have strong sculpture. The apex is mammillary. The anal sinus is varicose, and touches the sutural ramp. The columella is tuberculated posterior, rugose in front. It lacks columellar pleats. The siphonal canal is slightly curved, and varies in length between short to moderately long. The operculum is always absent in this family.
The family Clathurellidae appears to differ from the family Mangeliidae principally in its more rounded whorls and cancellate sculpture.
