Outer lip moderately convex, seemingly lacking teeth or lirae internally. Inner lip smooth except for three centrally placed and distinct columellar folds increasing in strength adapically on slightly curved columella.</paragraph>

Costae strongest peripherally on whorl, fading gradually out on adapical part of base and very abruptly at mid-whorl, completely disappearing shortly below adapical suture. This abrupt termination results in a marked pseudo-shoulder around mid-whorl and a flat to weakly concave shoulder slope on an otherwise flat whorl. Growth lines weakly sigmoid, nearly orthogonal on spire whorls.</paragraph>

by the sparse and exceptionally strong transverse rib sculpture forming a distinct shoulder before fading out close to the adapical suture. The typical costellariid sculpture, at least on early teleoconch whorls, is one of numerous and much finer transverse ribs. The generic assignment is for this reason rather tentative.
