They run at a large angle to the element axis, ending approximately at the cusp level, either at the platform margin or in the middle of the platform lobe. Porównanie In some specimens the posterior ridge continues further and approaches gently the platform margin. The tuberculation of the anterior lobe may be irregular or tubercles tend to be arranged in transverse rows. Autekologia Występowanie geograficzne Kowala in the Holy Cross Mts.
