vestigial. Maxillipedal palp consisting of five or fewer articles. Uropods uni- 

 ramous or biramous, rami usually much smaller than sympod. Pleonites 

 variously fused w^ith pleotelson; number of fused pleonites often indicated by 

 lateral sutures or furrows. 



REMARKS Brusca (1984) has reviewed the phylogeny, evolution, and bio- 

 geography of the subfamily Idoteinae, the only one of the five subfamilies 

 recorded from the Caribbean.
