Descrição original:

(Grego & Szekeres, 2008): “The thin-walled, light brown shell of 7 1/2 to 8 1/2 whorls has an elongated apex with a blunt tip. Following the smooth protoconch the apical whorls are covered with straight wrinkle-like ribs that become weaker and closer spaced toward the
basis. Except the rounded, densely costate neck, the last two whorls are almost smooth. The circular peristome has a broad white margin. The strong lamella superior is continuous with, but well distinguishable from, the less emerged spiralis. Leaning close to the superior, the outer end of the lamella inferior is often visible in front view of the shell.

The end of the lamella subcolumellaris, well visible through the aperture, is widely separated from that of the inferior. The plica principalis runs from the dorsolateral side to close behind the peristome. Below its inner ends starts a short, parallel plica superior. The
strongly bent lunella is fused with the plica superior and the posterior remnant of the basalis, resulting in a semi-circular structure on the dorsal side. The wide clausilium plate with a rounded tip is almost fully visible at an oblique view in the aperture”
