First teleoconch whorl with a median keel and very fine, arcuate axial plicules; a subsutural ridge develops on 2nd whorl, forming a strongly declivous, angularly keeled subsutural cord on later whorls; shoulder slope on later whorls strongly concave with 1-2 weak, slightly granular spiral threads, shoulder keel stronger than subsutural one; each whorl strongly concave below shoulder, with a fine intermediary thread and a spiral cord just showing at suture; base of body whorl with 8 sharp spiral lirae, posterior ones strong and widely spaced, those on rostrum rather weak, becoming obsolete terminally. Axial plicules in intervals thin but strong. Protoconch rather pupoid, of 2,5 vitreous whorls, smooth except for fine axial riblets behind termination, suture rather deep; breadth 0,45 mm, height 0,48 mm (b/h 0,94). Yellowish-white, tinged below suture with pale yellowish-brown. Columella with a vestigial pleat basally.
Resembles Oligotoma bellardii in some respects but with fewer, sharper spiral cords, finer axial threads and simpler, more concave intervals.
