Alvania subsoluta is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae. [1]
The length of the shell varies between 2 mm and 4 mm.
The thin shell is somewhat solid, white or brownishand opaline. It is rather numerously longitudinally costulate with riblets vanishing on lower part of body whorl. It shows less prominent, close, spiral striae that are stronger at the base. The shell contains five convex whorls, with a deep suture. The aperture is expanded below and externally varicose. [2]
This marine species occurs in the Atlantic Ocean off Iceland to Norway , the Canary Islands and West Africa; in the Mediterranean Sea off Sicily and Greece.
Fossils have been found in Pleistocene strata near Messina, Sicily.
