species of the genus; the 5th segment is broad, has a short, sharply 

 tapering distal process terminating in a spiniform cusp, and is notably 

 shorter than the posterior margin of the 6th segment; the 6th segment is 

 broad, its anterior margin straight, and a spoon-shaped extension covers 

 the claw for over half its length; the claw is thin, straight, and more 

 than half the 6th segment in length. Pereopods II are the same length 

 as pereopods I; the 2nd segment is narrower than in pair I, its width 

 1/3 its length, and the anterior and posterior margins are almost straight 

 and smooth; the lower distal angle of the 4th segment does not form 

 a spoon-shaped process; the 5th segment is not as broad as in pair I 

 but the distal projection is broad, terminating in a spiniform cusp, and 

 extends to the distal end of the 6th segment; the 6th segment, compared 

 to other species of the genus, is very broad, its anterior margin slightly 

 convex, and the spoon-shaped extension above the claw is much shorter 

 and narrower than in pair 1; the claw is thin, straight, and approximately 

 half the length of the 6th segment. Pereopods III and IV are equal in 

 length; the 2nd segment is narrow, its width less than 1/3 its length; 

 the 5th segment is somewhat longer than the 4th, broadens distally, and 

 its posterior distal angle is straight and not stretched into a denticulate 

 process; the 6th segment is somewhat shorter than the 4th and 5th seg- 

 ments together and its surface covered with setae; the claw is straight 

 and 1/3 the length of the 6th segment. Pereopods V-VII are about the 

 same length as pereopods III-IV; the 2nd segment is narrow and linear; 

 the 5th segment is significantly longer than the 4th; the 6th segment
