Bouchet, Kantor et al. elevated in 2011 the subfamily Mitromorphinae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistic analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments.
The Mitromorphidae have small to medium-sized shells with a high biconic mitriform shape, a paucispiral or multispiral protoconch up to 4.5 whorls, a short or indistinct siphonal canal, narrow aperture with up to 3 columellar pleats, indistinct anal sinus on a weakly pronounced subsutural ramp, fairly smooth surface with spiral sculptural elements. There is no operculum, and the radula is relatively short, hypodermic in character with awl-shaped teeth, a swollen solid basal region, and may have a weak barb at the terminal end of the radular tooth.
This is a list of the accepted names of genera in the family Mitromorphidae (the main reference for recent species is the World Register of Marine Species).[3]
