, the lateral carinae of the carapace are not constricted; the posterodorsal margin of the sixth abdominal somite is unarmed; the palm of the major cheliped is armed with a small, but distinct dorsodistal tooth; the cutting edge of the minor chela is only faintly denticulate. The armament of the ventral margin of the merus of the major cheliped may be also significant, although some degree of variation is seen in other species of the genus (T. Komai, personal observation).

seems to differ from these two new species by the short antennal acicle, which does not reach the distal margin of the fifth segment of the antennal peduncle, and the sharply pointed posterolateral angles of the second to fourth pleura (Alcock 1901). In the two new species, the second to fourth pleura are angular or rounded; and the antennal acicle nearly reaches the distal margin of the fifth segment of the antennal peduncle.
