Caron (1985):
The acute periphery is accentuated by a thick, beaded and protruding keel. A concentration of pustules, forming a typical Y is present on the umbilical side of each chamber. The species differs from its ancestor R. monisaivensis in having a more protruding keel, raised sutures on the spiral side and typical on the umbilical side.
