Fig. 138. Hyperiella dilatata Stebbing (after Bowman, 1973). 



The telson is the same length as urosomite III and only slightly less than 

 half the length of the basipodite of uropods III. 



Notes: The original descriptions of the two species examined 

 above were based on specimens of different sexes (H. antarctica, male; 

 H. dilatata, female). The differences between them are not very distinct 

 and possibly lie within the limits of intraspecific variation. 



Distribution: Circum- Antarctic; found from the coasts of Antarctica 

 to the Antarctic Convergence.

Walker, 1906: 452, 1907: 7 (Hyperia); Barnard, 1930: 412 (Hype- 

 ria); Hurley, 1969: 33 {Hyperia); Bowman, 1973: 30. 



Length of sexually mature specimens up to 13 mm.
