superior lamella continuous with spiral lamella without a curve, lamellae at the connection not lowered, spiral lamella hardly lower; inferior lamella high in position (near superior and spiral lamella), spirally ascending, low to moderately high inwards, in front ending on the columellar edge; subcolumellar lamella descending to the lunellar, ± connected with lunella; lunellar dorsaldorsolateral in position, in part dorsolateral, principal plica ending dorsolateral-laterally or laterally; upper palatal plica connected with lunella by an angle, lunella of different strength, weakened especially above together with upper palatal plica, hardly curved; clausilium plate in oblique view fully visible, distally ± pointed, in part leaving gaps, especially at the palatal side.
