Portunus Weber, 1795<br />
(This genus has traditionally been divided into subgenera, based on<br />
morphological critera. Modem studies of Portunus (Stephenson and Rees,<br />
1967; Stephenson, Williams, and Lance, 1968) have raised serious doubts<br />
about the subgeneric relationships and they suggest that further study<br />
will be necessary to define the complex phylogenetic affinities of this<br />
group, including the closely related genera, Arenaeus and Callinectes.<br />
As in Williams (1965), subgeneric catagories are deleted here.)<br />
