Peristome rounded to angular, with somewhat swollen margin. Lamellae superior and spiralis long overlap. In front view lamella subcolumellaris not visible. Lunella dorsolateral to lateral, separate from the weak basalis. Subclaustralis residual, sulcalis strong. Anterior plica superior mostly absent, if present separate from the lunella complex. Clausilium plate occasionally visible through the aperture.
