Marginal slopes of convex dorsal surface smooth and glistening (when wet), central part and transverse lines variably granulate. Pincers granulate on ridges, fingers of major hand heavily toothed; fifth legs flattened in form of paddles. Male with T-shaped abdomen reaching to anterior 1/4 of thoracic sternite 4; slender first pleopods sinuously curved overlapping in 2 places proximally, diverging distally then recurving to termination near midline and tip of telson, armed distally with dorsolateral band of large and small retrogressive spinules. Color: carapace olive green with variable tints of brown and blue distally, articulations and spines of legs orange and blue; underparts cream and light yellow with suffusion of light blue.
