The tips of the chelae are white. There are no spiny ridges on the carpus, propodus, or dactyl of the chelae, though there are two spines or tubercles on the dorsal ridge of the dactyl. The appendages seen covering the mouth are the maxillipeds, which are found in all crabs. The white objects between the maxillipeds are the hardened tips of the mandibles.
