Alvania punctura is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae. [2]
The length of the shell attains 3 mm.
(Original description) The very glossy shell has rounded whorls, rather taper in shape, and finely reticulated. The colour of the shell is transparent yellowish-white. The aperture is sub-orbicular and has a thin lip. The ridges on the body whorl do not extend over the outer lip. The shell has a small umbilical chink. The length of the shell is the tenth of an inch. Its breadth one third its length. [3]
This species occurs in the Eastern Atlantic, from Norway to the Strait of Gibraltar; intertidal to ca. 100 m depth; rare and rather local in the Western Mediterranean ( Corsica, Greece) in 50-200 m. Gorringe Ridge and Ampère Seamount, rare in 265-320 m. It is absent from Baltic Sea and the eastern basin of the English Channel. [2]
Fossils have been found in Pleistocene strata on Sicily, Italy.
