Quinnia is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the subfamily Seguenziinae of the family Seguenziidae.[1]
Quinnia is a replacement name for Seguenziella Marshall, 1983, a junior homonym of Seguenziella Neviani, 1901
Description
The shape of the shell is conical. It has a peripheral carina and sharp, collabral axial riblets. There is no microsculpture. All whorls possess midwhorl angulation. Spiral lirae are present on some whorls. The shallow posterior sinus has a V-shape. The anterolateral sinus forms a channel. The basal sinus is present. There is no columellar sinus. The aperture has a rhomboidal shape. The columellar tooth is present. There is no umbilical septum.
Radula: the rachidian tooth is higher than broad and has lateral wings reduced or absent. The lateral tooth cusp is narrow. There are less than 10 marginal tooth pairs.[2]
