are somewhat longer than the first ones. The 2nd segment of pereopods I 

 has weakly bulged sides, and its length is the same as the rest of the 

 limb; the 5th segment is barely wider than its length, the posterior distal 

 angle forms a small roundish lobe with unevenly denticulate margins, 

 the denticles on its tip larger than those on the margins, and the lobe 

 together with the 6th segment forms a subchela; the 6th segment has a 

 uniformly bulged anterior margin, a straight denticulate posterior margin, 

 and bears on its surface, like the posterior side of the preceding segment.
