Lunella dorsal, short and broad, not fused to the basalis. Subclaustralis not recognizable. Sulcalis well developed. Anterior plica superior weak, not connected to the lunella complex. Lunella dorsal-dorsolateral to dorsolateral, short and broad, mostly fused to the basalis. Subclaustralis weak or absent, sulcalis well developed. Anterior plica superior not connected to the lunella complex.
