Diagnosis
ReferenceDiagnosis
D. Heidelberger and M.R.W. Amler 2002The features of the genus apply; adapical spiral lirae consist of numerous, very small nodes.

The preservation of the single Dornap specimen is moderate. The small, thin shell consists of five well-rounded whorls. It is 6 mm high and 5 mm wide; the whorl diameter increases slowly and regularly; the sutures are deeply incised. The aperture is simple, rounded and continuous. The convex base is anomphalus or minutely cryptomphalous, ornamented with about six fine equidistant lirae. The ornamentation of the whorls consists of about five or six equidistant spiral, somewhat nodose lirae.
