Small chitons with wide, low intermediate valves. Jugum smooth, wide wedge-shaped, with wavy side margins. Tail valve as wide as head valve, oval, with central, low mucro. Pustules on tegmentum elongate oval, which are fused in the posterior margins of the head and intermediate valves; top of pustule flat, with 2–3 aesthete pores on top and several aesthete pores on the prepustular slope. Aesthete pores present also on tegmental plain. Dorsal side of girdle beset with minute, sharply pointed, strongly ribbed spicules intermingling with sharply pointed, smooth needles.
