Valva with stout costa shorter than half length of valva; sacculus narrow at base, widened medially, ventral margin straight in basal half, concave inward in distal half, with a large ventroapical spine; cucullus elongate triangular, slightly shorter than half length of valva, convex on dorsal margin, blunt at apex.
