Inner lamellae moderately broad, without vestibules and with numerous flexous to straight marginal pore canals; normal pore canals include simple open and celated pores as well as sieve pores; hinge hemiamphidont; central muscle scars comprising four adductors in subventral series, plus two frontal scars and two mandibulars.
