Last whorl with yellowish brown spots and flecks and with a network of fine brown lines edging tiny to moderately large, round to tentlike ground colour markings. Similarly sized tents may be arranged in groups. Yellowish brown spots and flecks interspersed with broad dark brown axial lines, sometimes also with spiral lines, usually forming 2 interrupted spiral bands, within basal third and just above centre. Larval whorls pale pink. Early postnuclear sutural ramps pale pink. First 2-4 ramps immaculate, following ramps matching last whorl in colour pattern. Aperture pink, sometimes suffused with orange or violet.

Medium-sized to moderately large, moderately solid to solid. Last whorl conoid-cylindrical, sometimes ventricosely conical, conical, or cylindrical, outline convex at adapical fourth, slightly convex to straight and parallel-sided below, with straightly tapering sides at basal third; left side constricted above base. Shoulder angulate to rounded. Spire of low to moderate height, outline straight to slightly concave or slightly sigmoid. Larval shell of about 2.75 whorls, maximum diameter 0.8-0.9 mm. First 4-5.5 postnuclear whorls tuberculate. Teleoconch sutural ramps slightly convex to slightly concave, with 0-1 increasing to 9-10 weak spiral grooves or more spiral striae.
