description
Description. The brownish-corneous, slender spindle-shaped shell consists of 12.3 to 13.5 whorls. The apical part is elongate, its tip is pointed. The teleochonch whorls have strong and sharp ribs (25 to 28 on the last whorl), which become bulkier but not more widely spaced behind the aperture. The last whorl becomes narrower toward the base, which has a prominent basal crest. The relatively small aperture is oval to somewhat diamond-shaped, its wide peristome is slightly projected. The thin, weakly emerged lamella superior reaches the margin of the peristome. Inward it converges slightly toward the lamella inferior and terminates well before reaching the lamella spiralis, which starts ventrally and ends dorsally. The lamella inferior ends high and deep, its terminal part is only barely visible in apertural view of the shell. Ending even deeper, the lamella subcolumellaris cannot be viewed through the aperture. The plica principalis spans one third of the last whorl starting from the lateral side. The well discernable, dorsolaterally positioned upper plica runs close and parallel to it. Farther toward the base there are two or three lump-like reduced plicae, and a stronger and larger but also diffuse, callus-like basal plica. The broad clausilium plate widens before ending abruptly in a short, pointed tip. In some of the specimens its parietal margin is visible in oblique view through the aperture.
