Shell oval-cylindrical, somewhat elongated, whorls very convex, with a deep suture.
Protoconch with about 1 whorl or a little more, the separation with the teleoconch being very difficult to see; diameter: nucleus about 130 µm; first whorl, about 260 µm. Microsculpture with a rough surface with minute depressions and -numerous irregular lines. Teleoconch with a little more than three whorls, which are very convex and show on their lower part an angulation which, on the last whorl, changes into a wide not very prominent spiral cord. The microsculpture is made of curved growth lines prosocline in the subsurural area and orthocline on the lower part.
Aperture almost circular, very irregular, continuous and undulating fine peristoma. Externally, a little before the end of the spire, there is a prominent elevation which is placed on the spiral cord, not elongated axially and which forms in the inner part of the aperture an important depression. It is not present in juveniles. Dimensions between 1.7 and 2.1 mm in height. The holotype is 2.0 mm high.
Animal dark, with tentacles dark with a white line in the middle; the dorsum of the head is dark with only white circular spaces around the eyes, which are black; the dark colour extends to the anterior part of the snout, which is white; behind the eyes there is a triangular space with cream or cream-yellowish colour; the sole of the foot is white. The penis is wide, sharp, with a narrow base, and one or two undulations on its internal border; a black longitudinal line is visible near the external border.
The radula is typical of hydrobids, similar to the previous one but with less prominent lateral cusps in the rachidian tooth and also in the internal border of the lateral teeth.
Habitat: Under stones (limestone) lying on a coarse sandy bottom; always on surfaces devoid of all (macro) vegetation.
