Description
Color: Dirty yellow or grey color, fingers of chelipeds black with whitish tips.

Lobules of carapace not very numerous, not convex, smooth, upper surface of wrist and hand somewhat rough.

Carapace moderately convex. The two lobes of the front have the free edge not merely emarginate, but deeply concave, so that the front appears to be formed of four little teeth. The fingers are not so broad at tip and not so sharply hollowed out. The upper surface of wrist and hand is more rugose. The front even narrower, it being less than one-fifth the breadth of the carapace. The anterior male abdominal appendage is cruved, and has its tip flat and arrow-headed and covered with long spines.
