Epimerons I-III have a round posterior angle. The telson is some- 

 what less long than its width at the base and does not reach the middle 

 of the basipodite of uropods III. 



Distribution: Warm-water regions of the Atlantic and Indian Oceans, 

 including the Arabian Sea.

4. Lestrigonus macrophthalmus (Vosseler, 1901) (Fig. 165) 



Vosseler, 1901: 70 (Hyperia); Yang, 1960: 19 (Hyperia); Bowman, 

 1973: 48. — (?) hydrocephala [(non Vosseler, 1901: 74 {Hyperia)] ; Dakin 

 and Colefax, 1940: 121 {Hyperia). 



Length of sexually mature males 3-4 mm, of females 2-3.5 mm. 



The head is more spherical than in other species of the genus, its 

 length more than half its height, and in females even exceeds the length 

 of the fused somites of the pereon. In females somites I-IV, in males 

 somites I-II of the pereon are fused. 



The cone of the antennal gland is rounded at the bottom and in 

 females reaches the lower margin of the mouth cone and even projects 

 beyond it, but in males is shorter. 



The mandibles have seven denticles on the cutting edge. The outer 

 lobes of the maxillipeds are narrow, with two apical setae and two-three 

 setae on the inner margin; the inner lobes have two apical spines.
