Description
Size: Length: female 0.50-0.92; male 0.60-0.80 mm.

Female: The widest part of the prosome is at the base of the cephalosome. The genital segment is twice the length of the rest of the urosome. The furca is nearly twice as long as wide. The distal spine on the 2nd segment of the maxilliped is thicker but of a similar length to the proximal spine. Approximately half of the inner margin of the terminal claw is lined with spinules.

Male: Genital segment is 3 times longer than the rest of the urosome. The lappets are large, rounded with a pointed projection directed outwards. The terminal claw on the maxilliped is not as long as the preceding segment. The furca are approximately twice as long as wide.
