5th segment is broad at the base and does not reach the end of the 

 6th segment; the claw is strong and half the length of the 6th segment. 

 Pereopods III-IV are identical; the 2nd segment is equal to the 3rd-5th 

 together; the 4th segment is elongated, slightly broadened, especially in 

 pereopods III, and equal to the 6th segment in length; the 5th segment is 

 almost half the length of the 6th; the 6th segment is narrow; the claw is 

 strong, slightly curved, and half the length of the 6th segment. The 2nd 

 segment of pereopods V is broadened, twice longer than wide; the 4th 

 segment is equal to the 2nd in length; the 6th segment is slightly longer 

 than the 4th and twice longer than the 5th; the claw is about 1/3 the length 

 of the 6th segment. Pereopods VI are similar to pair V. Pereopods VII 

 reach the 5th segment of pair VI; the 2nd segment attains maximum 

 width in the proximal part; the ratio of length to maximum width is 

 3:2; the rounded lobe of its posterior margin extends to the middle of 

 the 4th segment, and its anterior margin is distally stretched acutely; the 

 total length of the remaining segments is equal to or slightly more than
