The 2nd segment of pereopods I and II is almost linear and has 

 parallel margins; the distal segments together are shorter than the 2nd 

 segment and all the segments are fairly short; the 4th segment is distally 

 broadened, its length less than its width; the distal process of the 5th 

 segment has denticulate margins, is pointed, and its tip reaches the base 

 of the 6th segment, but in pereopods II is longer than in pereopods I; the 

 5th segment without the distal process is wider than long; the 6th segment 

 has a denticulate anterior margin, at least in the distal half. Pereopods III 

 and IV are simple, relatively thin, and long; the posterior margin of the 

 5th-6th segments of pereopods FV is denticulate. The 2nd segment of
