Description:

The abdomen of this species is thick and soft. The basal segment and the two distal segments have some calcified plates, which are not evident in this view. One claw is much larger than the other. The "palm" of the chela on the large claw is longer than the dactyl. The upper surface of the chelipeds is covered with prominent, granular tubercles but with no obvious spines.
