Description.

As for the type species.

Remarks.

The shell shape, convex whorls, and round, large aperture remind of species of Ecrobia, such as the co-occurring Ecrobia sp. The presence of ribs, however, makes the species unique and clearly distinguishes it from any other known species or genus of Hydrobiinae (or other Hydrobiidae for that matter).
