In addition to dignathic heterodonty seen in male teeth, sexual heterodonty is evident in that male lower teeth are more gracile than female lower teeth.
The scarcity of these morphotypes (1%) makes it difficult to tell as yet whether they are distinct taxa or whether they might represent heterodonty in one of the four recognized morphotypes.
Differences in morphology suggest that they do not represent teeth from different positions in the jaw of a taxon with heterodonty and that they therefore represent separate taxa.
