The last urosomite is equal in length and width. The basipodite of 

 uropods I is 3.5 times longer than the rami. The endopodite of uropods II 

 is fused with the basipodite and 2/3 its length. The margins of the 

 basipodite of uropods I and II are not denticulate. The endopodite of 

 uropods III has a straight anterior margin and a bulged posterior one. 

 The telson is less than 2/3 the length of the last urosomite. 



Distribution: Known from the Indian (region of Zanzibar) and Pacific 

 (region of New Zealand) oceans.

Length of sexually mature females up to 10.5 mm, of males up to 

 8 mm. 



The head is anteriorly smoothly rounded and its height more than its 

 length; in females its length is equal to the first five somites of the pereon, 



386 in males somewhat shorter. The pereon in females is high and dorsally 

 dolioform, in males still narrower. The last somites of the pereon and 

 one or two somites of the pleon may have an upcurved posterior margin. 

 In antennae I the 1st segment of the flagellum in males has a posterior 

 distal projection, almost equal in length to the 2nd segment. 



In coxal plates III-V the anterior distal angles project forward and 

 form processes with a rounded tip. Pereopods I and II are identical in 

 structure and have a subchela; the length of the 5th segment along the 

 anterior margin exceeds its width and is equal to the distal margin; the 

 posterior distal angle of the 5th segment (without extended tip) is more 

 than 120° and the tip stretched and pointed; the 4th and 5th segments 

 are armed along the posterior margin with numerous very small marginal 

 and submarginal spines; the margins of the subchela are not denticulate; 

 the claw is generally longer than 2/3 the length of the 6th segment. The 

 2nd segment of pereopods V has barely bulged margins and is twice 

 longer than wide; on the 4th segment the denticles are smoothened and 

 sparse, on the 5th and 6th segments somewhat dense and pointed. The 

 2nd segment of pereopods VI is shorter and broader than in pereopods V. 

 The 2nd segment of pereopods VII is large and strongly broadened; the 

 distal segments together are 1/4 the length of the 2nd segment; the claw 

 is often absent. 



387 The basipodite of uropods I is 2-2.5 times longer than the rami, 

 its anterior margin denticulate throughout its length, and the posterior 

 margin either smooth or with denticles in the distal part. The basipodite 

 of uropods II may have denticles in the distal part of the posterior margin; 

 the endopodite is not shorter than the basipodite. The endopodite of 

 uropods III is usually fused with the basipodite. The last urosomite is
