Valva broad and parallel-sided basally, narrowed toward cucullus; cucullus about half the length of valva, extending dorsad distally, expanded at basal 2/5, thereafter narrowed toward bluntly rounded apex, arched ventrally; costa straight in basal 1/5, semicircularly concave in distal 4/5; sacculus banded, straight ventrally.
