1. The network pattern on the carapace with smaller and more meshes.
2. Front narrower and much more produced than the innerorbital tooth, median notch deeper; innerorbital tooth with the anterior margin more convex.
3. Merus of the chelipeds with more obtuse teeth on its anterior margin. Carpus with its inner margin not concave. Palm longer; the movable finger slightly shorter than the dorsal margin of the palm.
4. Tip of the first pleopod of the male with a shorter prolongation and armed with more spines on its inner and outer margins. Telson of female abdomen longer than the sixth segment. (Dai & Yang, 1991)
