Girdle: Wide with sparse flat glassy hairs having several recurved spines at the base. Mucro: Strongly posterior. Valves: Beaked slightly. Central areas: Longitudinally ribbed and where each rib touches the lateral area there is a granular pustule. Pustules: Form a heavy lateral rib; from this rib the central area rib continues at an oblique angle on the lateral areas until it again reaches a granular pustule at the posterior edge of the valve; pustules form another granular rib along the posterior edge of each valve.
