Description

The diameter of the shell attains 8.3 mm, its height 4.2 mm.

(Original description in German) The shell is very flat and conical, with an almost flat apex and a moderately flattened, not very wide and continuously umbilical lower end. It comprises five flatly arched whorls, separated by deep sutures. The body whorl measures approximately three-quarters of the total shell height. The obliquely positioned aperture is broadly moon-shaped and features simple, sharp edges.[2]

Distribution

Fossils of this extinct species were found in late Miocene strata in the Vienna Basin, Austria.[1]
