Ventral rim well rounded, deep, very regularly curved; dorsal rim much shallower, likewise regularly curved, sometimes with very mild obliquely cut postdorsal section. Rostrum and antirostrum short, of equal length, with very small excisura in between; posterior rim regularly curved. Rostral tip and posterior tip positioned at lower margin of sulcus and distinctly supramedian. All rims delicately crenulated, ventral rim usually more intensely than dorsal rim.

In addition, the postdorsal termination of the cauda is less strongly bent upwards and at a less sharp angle than in the extant species.
