The 3rd usosome segment is longer than the 4th segment. The furca is as long as the anal segment. Maxilliped, the 2nd segment has two spines, the distal spine is thicker and longer than the proximal spine, and the inner margin of the terminal claw is lined with spinules.
Male: Considerably smaller than the female. There is no dorsal hump on the 2nd free pedigerous segment of the prosome. The genital segment is 3 times longer than the rest of the urosome. The lappets at the posterior corners of the genital segment are large, triangular and pointed outwards.
