Dianella is a little-known genus of small freshwater snails with a gill and an operculum, aquatic gastropod molluscs in the family Hydrobiidae.[3]
Distribution
These are European freshwater snails; they occur in southeastern Europe, from northern Italy, through the Balkans, to the Black Sea and the Caspian Sea
Description
Their relatively big shell has an onic or turriform shape with a common, prominent, spiral sculpture. The radula shows a rhachidian tooth with no basal cusps. Their stomach has a caecal appendix at its pyloric end. They have a Hydrobia-like central nervous system, a simple penis and a characteristic, big seminal receptacle at the end of a prominent spiral of the coiled oviduct.[4]
