Animal small. Valves moderately elevated, rounded, not beaked. Lateral areas not raised. Tail valve with mucro anterior. Central areas with about 28 almost longitudinal vague rows of weakly raised, oval granules. Each granule with one megalaesthete and four, rarely two, micraesthetes. Dorsal scales wide, obtusely pointed, with 9–11 distinct ribs. Radula with numerous transverse rows of very small teeth. Central teeth narrow, first lateral teeth narrow and long, major lateral teeth with long tridentate cusp. Seven gills per side.
