Daphnella is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. [1]
Not to be confused with DaphnellaBaird, 1850, a synonym of Diaphanosoma Fischer, 1850 belonging to the Sididae, a family of ctenopods.
This genus is well characterised by a small, thin shell, elongate-ovate form, a sharp outer lip, the position of the sinus on the line of the advancing suture, and by the reduction of the siphonal canal. The protoconch has a sinusigerid (or diagonally cancellate) structure. The surface is usually striated. The spire is elevated, the body whorl is elongated. The early whorls of the teleoconch show a nodulous sculpture produced by strong axial riblets and strong spiral lirations. These axial riblets disappear on the body whorl, while the spiral lirations remain. The aperture is oblong-oval, slightly channelled in front. The columella is simple. The outer lip is slightly thickened in the adult. [2] [3] [4]
