REMARKS The inability to place Mexicope in a family reflects the fact that 

 the arrangement of the families and genera of the Janiroidea is still unsettled. 

 While having affinities with the Pleurocopidae and the Janiridae, placement 

 in either of these would require redefinition of both families, making the 

 Janiridae even more of a hodgepodge of phylogenetically unrelated genera.

 Figure 37 



DIAGNOSIS d 1.7 mm, 9 2.9 mm. Antennae slightly longer than body. Per- 

 eonites and pleon laterally finely serrate. Pleotelsonic lobe between uropodal 

 bases narrowly rounded, barely produced. 



RECORDS Turks and Caicos Islands, 1 m; Florida Middlegrounds, Gulf of 

 Mexico, 30 m. 



Family Janiridae Sars, 1899 



DIAGNOSIS Antennae longer than antennules. Mandibles with palp and 

 well-developed molar. Maxilliped with articles 1-3 at least as wide as endite, 

 markedly broader than articles 4 and 5. Pereopod 1 prehensile, subchelate, 

 sexually dimorphic, larger in 6 than in 9. Pereopods 2-7 ambulatory, dac-
