Clathurellidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.[2][3]
In the taxonomy of the Gastropoda by Bouchet & Rocroi (2005)[4] Clathurellinae was classified as a subfamily of Conidae.[4]
In 2011 Bouchet, Kantor et al.[2] brought some genera from the subfamily Clathurellinae (at that point belonging to the family Conidae) in a new family, Clathurellidae.[2] This was based on anatomical characters and a dataset of molecular sequences of three gene fragments.[2]
Species in this family have small to medium-sized fusiform shells that have strong sculpture.[2] The apex is mammillary.[citation needed] The anal sinus is varicose, and touches the sutural ramp.[2] The columella is tuberculated posterior, rugose in front.[citation needed] It lacks columellar pleats.[2] The siphonal canal is slightly curved, and varies in length between short[citation needed] to moderately long[2] (as in Glyphostoma rostrata). The operculum is always absent in this family.[2]
The family Clathurellidae appears to differ from the family Mangeliidae principally in its more rounded whorls and cancellate sculpture.
