Shell with a smooth, heterostrophic top-whorl, formed by 5-6 strongly carinated whorls. Three keels, the first further apart from the other two, are recognisable on the teleoconch whorls and on the upper half of the body whorl. At the base, 5-6 more spiral keels visible. Axial sculpture of raised lines which are seen between the spiral keels. There is a narrow, but deep, umbilical chink and a tooth on the columella.
common size :
up to 4.5 mm.
The more conspicuous spiral sculpture, together with the evident prosocline growth-lines, make this species easily distinguishable from all the other Mediterranean pyramidellids. Perhaps, shells of this species with damaged apex could induce to a hurried identification with some rissoid species (e.g. Alvania weinkauffi (Weinkauff, 1868).
BIOLOGY / ECOLOGY
On the basis of the living specimens found along the Turkish coasts, it is possible to assume that this is a shallow water species.
5-6 m depth.
