Diagnosis

Reference	Diagnosis
P. Y. Parkhaev and Y. Demidenko 2010	"Planospiral shell composed of one or two evolute, laterally compressed, and rapidly expanding whorls. Exterior shell ornamentation composed of concentric folds and ribs, developed in various extent, rarely thin radial ornamentation can be present. Ornamentation of internal mold similar to that of shell. Aperture elliptical or elongated oval, without flaring; sometimes posterior sinus can be present."
