Fig. 157. Parathemlsto (Euthemisto) australis (Stebbing) (after Hurley, 1955). 



303 5th segment is much narrower, elongated-oval, and without a setose (or 

 setaceous) cover; the 6th segment is narrow, almost linear, and somewhat 

 longer than the 5th; the claw is strong, almost straight, and approximately 

 half the length of the 6th segment. The 5th segment of pereopods IV is 

 elongated-oval, with strong setae along the posterior margin, and almost 

 identical in males and females; the 6th segment is equal in length to the 

 5th. Pereopods V are longer than the preceding ones; the 2nd segment 

 is relatively short, broad, and almost equal to the linear 5th in length 

 but twice longer than the distally broadened 4th segment; the linear 6th 

 segment is straight and approximately 1.5 times longer than the 5th; the 

 claw is strong and almost straight. Pereopods VII are somewhat shorter 

 than pereopods V; the 4th segment is 3/4 the length of the 5th and both 

 are almost linear; the 6th segment is narrower but 1.5 times longer than 

 the 5th and both bear a row of strong setae on the posterior surface; 

 the claw is strong, almost straight, and about 1/3 the length of the 6th 

 segment.
