Shell size 4.4 mm; tall, bluntly conical; height 44% of length. Pure white. Protoconch of one rounded whorl (Fig. 124); situated on right; smooth, glossy; of 210 µm. Foramen cuneiform (pointed anteriorly), width ca. 10% of length; located between anterior and middle thirds of shell length; ca. 10% of shell width, 23% of shell length; edges irregular (Figs 121, 123, 125). Groove anterior to foramen very narrow, flanked by pair of cords similar to neighboring cords. Profile curved ventro-posteriorly; middle third of dorsal surface somewhat straight, parallel to apertural plane; total angle (excluding planar middle region) ca. 80° (Figs 122, 124); beak in posterior ¼ of shell length (in dorsal view), between dorsal and middle thirds in lateral view. Sculpture of ca. 40 narrow radial cords (Figs 121, 122, 124); cords increasing in strength towards aperture; primary, secondary cords intercalating (Figs 122, 124); concentric cords regularly distributed, as wide as radial cords, except close to margin, with radial cords somewhat stronger; radial, concentric sculptures forming delicate reticulation composed of series of rectangular pits (each rectangle about twice as long as tall, longer axis parallel to shell edges); interspaces between cords twice cords width; ca. 60 concentric cords along cords close to median line. Selenizone well-marked, edges as tall as radial cords, twice as tall as foramen edges, projected dorsally, with sharp edges; lunules regular distributed (Fig. 125). Aperture planar (Fig. 122), outline elliptical, width ca. 60% of length; edges slightly undulating due to radial cords. Inner surface smooth, glossy (Fig. 123).
