Animal of small size. Valves lowly elevated, carinated. Tail valve wider than head valve, mucro subcentral. Tegmentum with distinct oval granules arranged in longitudinal rows on central area of intermediate valves and antemucronal area of tail valve and quincuncially in other areas. Each granule with one megalaesthete and eight surrounding micraesthetes. Dorsal scales elongate, sharply pointed, with one rib. Central teeth of radula rectangular, major lateral teeth with short unidentate distally narrowed cusp. Eighteen gills per side from valve III to anus.
