Small chitons with beaked, low intermediate valves. Jugum wide wedge-shaped, smooth on surface. Tail valve small, oval, with central, low mucro. Pustules on tegmentum droplet-shaped or round, quincuncially arranged; top of pustule flat, with single macraesthete pore and 7–8 micraesthete pores. No micraesthete pores on tegmental plain.
