The carapace is broader than long and the front slightly projected in the middle. The antero-lateral border is crested with a plate-like margin, which is marked with three closed fissures. Chelipeds and ambulatory legs are, like the antero-lateral border elegantly separated in areolae and covered with granules. (Sakai, 1983)
