Antenna 1 reaching a short distance beyond peduncle of antenna 2, 1st and 2nd joints subequal, 3rd shorter, flagellum a little longer than peduncle, 20-jointed. Antenna 2, 4th joint slightly longer than 5th. Gnathopod 1, 5th joint oblique, distally produced forwards, 6th oblong, longer than 5th, palm a little longer than hind margin, and defined by a long spine, with a small tooth below the spine. Gnathopod 2, the narrow process of 5th joint extending only half-way along lower margin of 6th joint, which is narrow oblong, palm defined by a long spine. Peraeopods 1 and 2 stout, 4th~7th joints rather strongly expanded, 5th and 6th joints subequal, 7th a trifle longer than 6th, cultrate. Peraeopods 3 and 4, 2nd joint narrow pyriform, posterior margin distally straight or slightly concave, 4th expanded, much wider than 3rd or 5th, 6th longer than 5th, 7th longer than 6th, almost as long as 4th. Peraeopod 5, 2nd joint broadly pyriform, 4th not expanded, 4th and 5th subequal, 6th a little longer. 18
