The mandibles are rudimentary and the mandibular palp absent in 

 females and, possibly, in males also. In maxillae I the palp is elongated- 

 328 oval, petaloid, and longer than the outer lobe. The outer lobes of the 

 maxiliipeds are petaloid, round, and bear a pair of short thin setae on the 

 distal margin; the inner lobes are narrowly triangular and almost half the 

 outer lobes in length. 



The 2nd segment of pereopods I is distally broadened and has a 

 convex anterior margin; the 5th segment is triangular and has a straightly 

 truncate distal margin that is three times broader than the base of the 6th 

 segment and articulates with the anterior part of the 6th segment; the 

 6th segment is narrowly conical; the claw is only barely smaller than 

 the 6th segment. The 2nd segment of pereopods II is narrow and the 

 distal process of the 5th segment half the length of the 6th segment. 

 Pereopods V are significantly shorter than pairs III- IV and VI-VII and 

 have an unusually long, slightly curved claw equal in length to the 6th 

 segment; the 5th segment is somewhat shorter but notably stronger than 

 the 6th segment. Pereopods VI and VII have the same length ratio among 

 the segments and the claws are equally long in both pairs. Their length 

 greater than the length not only pereopods V, but also of pairs III-IV. 



Distribution: A circumtropical species. It is known from the tropical 

 Atlantic (coastal areas of Florida), South Atlantic (coastal regions of 

 South Africa), the Mediterranean Sea, and the tropical part of the Pacific 

 Ocean (28° N, 155° W, the Fiji Islands).

14. Genus Phronimopsis Claus, 1879 



Claus, 1879a: 63; Bovallius, 1887: 23; 1889: 318; Stebbing, 1888: 1373; 

 Vosseler, 1901: 51. 



The body of males is narrow while in females the pereon is broad- 

 ened and flat. The height of the head exceeds its length and the eyes 

 occupy most of the cephalic surface. Somites I and II of the pereon 

 are fused in both sexes. Antennae I in females have a one-segmented 

 peduncle and one-segmented flagellum and are longer than the head. The 

 mandibles have a strong dentate process; the palp is absent in females. 

 The outer lobe of maxillae I bears apical spines. The maxiliipeds have 

 narrow outer and long inner lobes. The coxal plates are fused with the 

 somites of the pereon. Pereopods I are simple and the claw is densely 

 covered with setae. Pereopods II have a strong chela, formed by the distal 

 process of the hypertrophied 6th segment and the claw. Pereopods III-VII 

 are thin and have a poorly developed subchela, formed by the process 

 of the 6th segment and the claw. Pereopods III-IV and VI are equal in 

 length; pereopods V are distinctly shorter. 



Type species: Phronimopsis spinifera Claus, 1879.
