Seven small, ear-shaped and nearly equal-sized spine articulations in deep notches of the distal edge and partly overlapped by the undulose distalmost lamella; ventral lobes of spine articulations strongly increasing in size dorsalwards, conspicuously tongue shaped and connected with the distalmost lamella in all but the two ventralmost spine articulations; dorsalward increase in size of the gaps separating spine articulations; narrow gap between the four ventral spine articulations and the distal edge of the LAP.
