the 2nd segment; the 5th segment without the distal process is equal in 

 length and width; the distal process has straight denticulate margins and 

 its tip barely reaches the middle of the 6th segment. The 2nd segment 

 of pereopods II has an almost straight or slightly curved anterior margin 

 and a bulged posterior one; the denticulate distal process falls slightly 

 short of the tip of the 6th segment. The 2nd segment of pereopods III and 

 IV has a rather strongly bulged posterior margin and an almost straight 

 anterior one. The 2nd segment of pereopods V is broadly lanceolate and 

 the middle part of the anterior margin undulating. The 2nd segment of 

 pereopods VI has a concave anterior margin with a characteristic notch 

 in both the proximal and the distal part; in females the distal part of the
