Ventral interarea rather long, apsacline to nearly orthocline, moderately to strongly concave. Open delthyrium moderately wide (~50˚), V-shaped. Teeth triangular, developing strong crural fossettes in larger specimens. Teeth supported by recessive, slightly converging dental plates. Pedicle callist apically located in delthyrial cavity. Muscle field broad and often slightly raised above valve floor. Diductor scars subcordate, slightly diverging, separated by a median field of about double width. Adductor scars weakly impressed, slightly longer than diductor scars, reaching about 30% of valve length. Ventral mantle canal system saccate.
