in other species of the genus and its margins form an angle of 60-80° ; 

 the 6th segment is shorter than the 5th and its anterior margin is smooth; 

 the 3rd-5th segments are rather densely pubescent with marginal setae 

 but the distal process and the posterior part of the 5th segment bear 

 lateral setae. The 2nd segment of pereopods II has a concave anterior 

 and a bulged posterior margin; the other segments of pereopods II are 

 the same as in pereopods I and have similar ornamentation. Pereopods V 

 are similar to those in P. ovoides. The 2nd segment of pereopods VI has 

 a characteristic configuration: the anterior margin is straight in the distal 

 part but concave proximally and the width of the segment the same over 

 much of its length, unlike in P. ovoides where it begins to taper almost 

 from the place of articulation of the distal segments. Pereopods VII 

 consist of a broadened 2nd segment with a concave anterior and bulged 

 posterior margin, and two distal segments: a very short 3rd and longer 

 and recurved 4th segment. 



The basipodite of uropods I is much shorter than the rami; the two 

 rami are almost similar in shape and length but the exopodite is very
