Description
Size: Length of carapace: 32 mm.
Breadth of carapace: 65 mm.

Frontal teeth well separated; supraorbital tooth convex and not very broad; basal antennal segment with 4 to 5 spinules.
Carapace is less convex and the transverse ridges are very distinct. The front is somewhat more prominent, the teeth are closer set and the four middle ones are remarkably square cut. The teeth of the antero-lateral border end in spines and the fourth tooth is quite rudimentary and may even be altogether absent. The chelipeds are free from hair and that all the spines are large and much more acute. The propodite of the last pair of legs has its posterior border serrated throughout. The 6th abdominal tergum of the male is about as long as broad, and has gently convergent sides.

Abundantly seen in coral reefs at the depth of 0.5 to 1 meter deep. Large numbers of this crab are seen in corals thickly covered with seaweeds.
