5. Hyperia crassa Bowman, 1973 (Fig. 134) 



Bowman, 1973: 23. 



Length of sexually mature crustaceans 12-15 mm. 



The head is unusually large, longer than somites I-III of the pereon 

 together, its height notably more than its length. The somites of the 

 pereon are highly differentiated in height — II being the highest, VII the 

 lowest, and II-IV with a transverse fold. 



The 1st segment of the mandibular palp is significantly shorter than 

 the 2nd or 3rd segment. The inner lobes of the maxillipeds are long, with 

 long apical spines. 



The 2nd segment of pereopods I is broad and has a highly convex 

 anterior margin. Solitary spinules are present on the posterior margin 

 of the 4th-5th segments of pereopods III-IV. Pereopods V-VII are not 

 armed and have a comparatively narrow 2nd segment. The posterior mar- 

 gin of epimeron III is almost straight and only in the distal part slightly 

 convex. Uropods II and III have very broad basi- and endopodites. 



Distribution: Gulf of Guinea and Cape Verde Islands. 



Absent in our collections.
