than in pereopods II, narrows proximally, and is almost 2.5 times broader 

 in the distal part; the 5th segment is longer than the 4th; the 6th segment 

 is shorter and much narrower than the 5th; the curved claw is 1/3 the 

 length of the 6th segment. Pereopods V-VII are shorter than III and IV; 

 the 6th segment broadens distally; the strong curved claw together with 

 the braodened part of the 6th segment forms a unique prehensile organ. 

 The basipodite of uropods I is relatively broader than in the male and 

 three times longer than wide. The structure of the other legs does not 

 differ significantly in the two sexes. 



The oostegites are located on somites II- V of the pereon, irregularly 

 triangular in shape, and much longer than the gill sacs. 



Distribution: A surfacial circumtropical species known from the 

 tropical regions of the Atlantic Ocean, the Mediterranean and Red seas, 

 and tropical waters of the Indian and Pacific oceans. 



2. lulopis mirabilis Bovallius, 1887 (Fig. 141) 



Bovallius, 1887a: 17; 1889: 125; Spandl, 1927: 159; Shoemaker, 

 1945a: 238. 



Length of sexually mature males 6-8 mm, of females 6-7 mm. 



Male: The body is not laterally compressed and the pleon is the 

 same length as the pereon. The entire body integument is covered with 

 thin setae but the integument is not as thick as in /. loveni and the setae 

 are shorter and coarser. 



The head is equal in length to the first three somites of the pereon. 

 The eyes occupy the entire surface of the head; their facets are much 

 smaller and more numerous than in /. loveni. The "hairy" cover is 

 reduced to a small number of minute setae on the upper part of the head. 



Antennae I and II are equal in length in sexually mature males; 

 the 1st segment of the peduncle is thick, almost semicircular, and three 

 times longer than the next two segments together; the 1st segment of 

 the flagellum is strong, conical, much longer than all the segments of 

 the peduncle, end consists of more than 20 segments. Antennae II are 

 attached to the lower anterior angle of the head; the flagellum consists 

 of 20 segments. 



The 2nd segment of pereopods I is linear and equal in length to the 

 3rd, 4th, and 5th segments together; the 4th segment is wider than long 

 and its lower distal angle round; the 5th segment is dolioform, its lower 

 distal angle rounded and bears many short setae; the 6th segment is 

 elongated-conical, shorter and narrower than the 5th, its anterior margin 

 slightly convex, with dentiform spinules, and the segment compressed 

 to the distal margin of the 5th to form a subchela; the claw is deeply 

 curved and half the length of the 6th segment, its posterior margin densely 

 covered with dentiform spinules. Pereopods II are somewhat longer than 

 pereopods I; the 2nd segment is equal in length to the 3rd, 4th, and
