Fig. 143. Hyperoche mediterranea Senna (after Hurley, 1955). 



The 2nd segment of pereopods I is barely broadened, its maximum 

 width 1/3 its length; the process of the 5th segment in both sexes slightly 

 exceeds the length of the 6th segment; the process of the posterior distal 

 angle of the 4th segment is narrow, acute, and reaches the base of the 

 process of the 5th segment; the claw is thin and its posterior margin is 

 smooth. Pereopods II are similar in structure. The entire surface of the 

 285 4th, 5th, and 6th segments of pereopods I, but especially of pereopods II, 

 is covered with short thin setae. Pereopods III and IV are similar to those 

 in H. medusarum but the posterior distal angle of the 5th segment does 

 not have a triangular process and the posterior margin is not denticulate 

 but does bear short setae; the surface of the 4th-6th segments is covered 

 with short thin setae. Pereopods V-VII are identical in structure; the 2nd 

 segment is slightly shorter than the 4th and 5th segments together; the 

 6th segment tapers distally and is equal to the 2nd segment; the strong 

 claw is half the length of the 6th segment. 



The epimeral plates are roundish and their posterior angle is not 

 stretched into a cusp, although it may be slightly denticulate. The uropods 

 and telson are the same as in other species of the genus. The margins of 

 the uropods are more prominently denticulate in females than in males. 



Distribution: A bipolar species, found in the Mediterranean Sea and 

 the southern coastal region of New Zealand. It lives in shallow coastal 

 waters.
