Holotype IZCAS TM 010064 (Figs 6 C, 12 N), 29 paratypes IZCASTM 010065-010093. Type locality. Longxian County, Shaanxi Province. Brief description. Shell dextral, with about 6.5 whorls. Protoconch smooth. Penultimate whorl slightly expanded; body whorl nearly as wide. Teleoconch with thin, dense, radial ribs; ca. 7 ribs per 0.5 mm on penultimate whorl, ca. 6 ribs per 0.5 mm on body whorl. No double lip. Columellar tooth present.
