Shell (Figs 2 & 4) (description based on holotype): Fragile, semi-transparent, narrow cylindrical. Posterior tapering, forming constricted, slightly twisted canal that widens very slightly along outer edge. Slight development of callosity along peculiarly twisted funicular region, no funiculum visible. Columellar bulge faintly striate, not showing any callosity. Anterior tip pointed, formed by long, well-developed and slightly calloused fossular fold. Labral edge very thin and fragile, no indication of callosity. Last whorl glossy and smooth, showing fine, regular longitudinal growth-lines. Faint, distant incised striae visible on terminal collars and especially above the slightly callosed funicular region. Overall colour of shell rich orange-cream, calloused along posterior canal and fossular region slightly paler.
