This is a genus of asymmetrical biraphids characterized by clavate valves, uniseriate stria, and a stigmata in some species. This species is nearly symmetrical with apiculate apices. There is a single stigmata offset of the raphe in the central area. The stria opposite of the stigmata is shorter than those surrounding it. Helictoglossae are evident at the apices. Stria are slightly radiant becoming more parallel near the apices.
