and somite I of the pereon; the lower and upper margins are almost 

 straight and parallel; the anterior edge is obliquely truncate; the line of 

 truncation forms a distinct angle with the lower margin. Antennae II in 

 females are six- to seven-segmented and shorter than antennae I, in males 

 slightly longer and eight- to nine-segmented. 



The legs are long and strong. The 2nd segment of pereopods I has 

 convex margins and is shorter than the remaining part of the leg; the 

 posterior part of the distal margin bears four-five spiniform setae; simi- 

 lar setae are present in the posterior distal part of the 3rd-5th segments; 

 the anterior margin of the 5th-6th segments also bears two setae each; 

 the posterior margin of the 6th segment is straight and denticulate dis- 

 tally; the claw is strong, with denticles along the posterior margin, and 

 longer than half the 6th segment. The 2nd segment of pereopods II is 

 approximately equal to the rest of the leg; the posterior distal angle 

 of the 3rd segment has two spiniform setae; the lobe of the 4th seg- 

 ment is also armed with setae and extends to the base of the process 

 of the 5th segment; the anterior distal angle of the 5th segment bears 

 two setae, the acute process of this segment is denticulate from the inner 

 side and extends to the end of the 6th segment, the posterior and distal 

 margins of which are also denticulate; the anterior margin of the 6th 

 segment has three small spinules; the claw is denticulate posteriorly and 

 slighdy longer than half the 6th segment. Pereopods III-IV are strong, 

 with strong musculature; the 2nd segment has an S-shaped anterior mar- 

 gin and a convex posterior margin; the 4th segment broadens distally 

 and has a straight posterior and highly convex anterior margin; the 5th 

 segment is shorter than the 4th and its length slightly exceeds its width; 

 the 6th segment is equal to the 4th in length, its posterior margin slightly 

 concave with minute sparse spinules, and its anterior margin smooth 

 and slightly convex; the claw is almost equal to the preceding segment 

 in length or slightly shorter, posteriorly smooth, and has a few minute 

 denticles at the base. The highly developed 4th segment and the claws 

 are good diagnostic features of this species. The 2nd segment of pere- 

 opods V is broadened and shorter than in pereopods IV and the distal 

 part of the anterior margin has four strong spinules; the 4th and 5th 

 segments are equal in size and both bear a few spinules on the anterior 

 margin, while the 5th has one strong spine in the distal part of the ante- 

 rior margin. The 2nd segment of pereopods VI is equal in length to the 

 2nd segment of pair IV and is armed with five spines in the distal part 

 of the anterior margin; the 4th segment in the distal part of its anterior 

 margin and the 5th segment throughout its anterior margin bear strong 

 spines. The 6th segment of pereopods V-VI is longer than the 5th with a 

 finely denticulate anterior margin; the claw is long and straight and half 

 the length of the 6th segment. Pereopods VII extend to the end of the
