), much wider than high, shape conical with large apical angle, glossy; spire moderately depressed, height 0.61–0.63×width, about 1.71×to 1.89×aperture height; rounded to very slightly subangulate periphery; umbilicus very broad and deep. Protoconch ca. 250–350 μm wide, 1.25 whorls, rounded, translucent, with a straight terminal lip. Teleoconch up to 4.4 slight- ly convex whorls; early whorls with 5 spiral cords; intermediate whorls with subsutural axial pleats; last whorls smooth with faint spiral cords on periphery. Suture canaliculated on first whorls, impressed on last whorls. First teleoconch whorl convex, with 5 spiral cords appearing immediately and thin axial threads; P2 strongest, P1 almost as strong as P2, other cords P3, P4 and P5 slightly thinner; distance between cords about 1×to 1.5×width of cords. second whorl, all cords widening and flattening after half whorl; low axial pleats appearing, covering adapical third of whorl; S2 and S3 appearing on some specimens; axial threads disappearing. On third whorl, pleats stronger especially in subsutural area; all spiral cords vanishing. On fourth whorl, axial pleats weakening and vanishing, leaving only a smooth, rather thin, translucent subsutural spiral band. Last whorl completely smooth, except a few very weak spiral cords on periphery in some specimens. Aperture subelliptical quadrate; peristome incomplete; outer and inner lip thin; inner lip without thickening against umbilical rim. Base convex; two outer thirds smooth, inner third with reticulate pattern of 2–6 spiral cords and axial grooves on inner third; about 25–35 axial pleats reaching spiral cord bordering umbilical rim. Umbilicus broad (diameter 18–25% of shell width), central, with perspective to apex, with angulate rim, convex wall, axial threads and 5–8 spiral cords forming reticulate pattern inside.
