Lectotype NHMW 1867/0008/0039 (original illustration from Laube, pl.1, fig. 10) from Mid Jurassic of Balin in lateral view.

Diagnoza

Very slim, multi-coil shell with several spiral ribs widened in the form of a ribbon. The growth lines are opisthocyrtic and clearly prosocline. The rearmost point is in the middle of the coil or a little below. The aperture is broadly oval with an adapical point.

Porównanie

Most similar Pseudomelania extricata (Blake, 1905) has a wider shell, with lower in relation to its width. Other similar species, Proacirsa laevigata (Eudes-Deslongchamps) and Hudlestoniella struvii (Lahusen, 1883) are significantly wider.
