Length of carapace: 38 mm
Breadth of carapace: 35 mm
Length of lateral spine: 12 mm
Posterior breadth of composite segment 3-5: 8.75 mm
Median length of composite segment 3-5: 11.0 mm
Posterior breadth of segment 7: 3.0 mm
Median length of segment 7: 4.75 mm

Color: Yellow, with a multitude of violet speckles which fade into a red tint in spirit.

Carapace subcircular, almost smooth with indistinct tubercles, somewhat depressed and with a prominent horizontal spine at the lateral apibranchial angle, on either side; postero-lateral borders sharply convergent; front wider than the orbit. longitudinal ridge of dactylus of chelipad strongly milled; palm with spine-like teeth at the base of the lower outer angle near the wrist. last four pairs of thoracic legs oar-shaped for swimming. The anterior male appendage straight, slender with arowhead-like terminal portion bearing numerous blunt spinules, tubercles and hairs.

This species is distinguished by the presence of a distinct spine at the angle of the hand where it comes in contact with the external angle of the arm. The length of the composite segment 3-5 in the male is greater than its breadth at the base, and the length of the terminal segment is considerably more than its posterior breadth. Differention in the direction of spines was observed, some pointing forward, some laterally and some even backward.
