Taxonomy

2005 taxonomy

In the taxonomy of the Gastropoda by Bouchet & Rocroi (2005)[3] Clathurellinae was classified as a subfamily of Conidae.[3]

2011 taxonomy

In 2011 Bouchet, Kantor et al.[1] brought some genera from the subfamily Clathurellinae (at that point belonging to the family Conidae) in a new family, Clathurellidae.[1] This was based on anatomical characters and a dataset of molecular sequences of three gene fragments.[1]

Description

Species in this family have small to medium-sized fusiform shells that have strong sculpture.[1] The apex is mammillary.[citation needed] The anal sinus is varicose, and touches the sutural ramp.[1] The columella is tuberculated posterior, rugose in front.[citation needed] It lacks columellar pleats.[1] The siphonal canal is slightly curved, and varies in length between short[citation needed] to moderately long[1] (as in Glyphostoma rostrata). The operculum is always absent in this family.[1]

The family Clathurellidae appears to differ from the family Mangeliidae principally in its more rounded whorls and cancellate sculpture.
