), not umbilicate, dextral, slender, turrited with straight outline, rather thin, translucent, pale corneous. Whorls 10, slightly shouldered with a deep straight crenulated suture all the way to the aperture. Protoconch 2+ whorls, glossy with faint radial and spiral sculpture. Protoconch/teleoconch transition distinct because of change in macrosculpture. First whorl of teleoconch with well-defined radial ribs about same width as intercostal spaces. Surface of later teleoconch whorls with well-defined broad radial ribs much wider than intercostal spaces and with extremely faint, uneven and wavy spiral sculpture. Growth lines not visible. Aperture elongated, orthocline, with approximately 90° columellar-basal angle, cut by penultimate whorl, with faint whitish parietal callus enhanced on columellar edge. Apertural dentition of deeply sited, strong, short palatal tubercule, perpendicular short basal lamella about same distance from aperture edge as palatal one and large spirally curving downward columellar lamella. Penultimate whorl furnished with exactly the same dentition positioned half whorl from the apertural set. Peristome simple, acute, not reflected.
