than the 3rd-6th segments together; the strong, slightly curved claw is 

 equal to the 6th segment in length. The margins of pereopods I-IV are 

 smooth, without spines or setae. The 2nd segment of pereopods V In 

 males is weakly broadened; the 3rd segment is short; the 4th-6th are 

 359 very thin and straight, with a denticulate anterior margin; the distal seg- 

 ments together are four-five times longer than the 2nd segment; claw 

 is rudimentary, the 2nd segment of pereopods V in female is strongly 

 broadened; its anterior margin is almost straight, the posterior margin 

 bulged, the anterior distal process large, denticulate; the 3rd-7th seg- 

 ments together are only twice longer than the 2nd; the 4th segment is 

 the largest of the distal segments, with large, sparse denticles on the ante- 

 rior margin and a pointed posterior distal process; the anterior margin of 

 the 5th and 6th segments is serrate; the claw is short. The structure of 

 pereopods VI in males and females also differs sharply. The 2nd seg- 

 ment in males is almost oval, with a medially curved posterior margin, its
