Mitromorphidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.[1][2]
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 cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments.[1]
Description
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.[1]
