Shell medium, tumid, yellowish-brown. Lower whorls smooth, upper ones very finely, indistinctly costate. Neck not to weakly inflexed, finely and densely costate. Basal crest well recognizable, peripheral crest weak. Peristome attached, with strongly swollen, reflexed margin. Lamellae superior and spiralis overlap. In front view lamella inferior moderately emerged, broadly-bent subcolumellaris visible. Lunella dorsal, separate from the short basalis. Subclaustralis absent or residual. Anterior plica superior often connected to the lunella complex. Clausilium plate almost entirely visible through the aperture.
