"Four subgenera of the genus Penaeus are described (Litopenaeus, Penaeus ,, Fen- neropenaeus, and Melicertus). Eight species and subspecies (P. setiferus, P. schmitti, P. duorarum duorarum, P. duorarum, notialis, P. aztecus aztecus, P. aztecus subtilis, P. paulensis, and P. brasiliensis) are recognized as occurringinthe western Atlantic. Synony- mies are given. Lectotypes have been desig- nated for two species, and the disposition of all types is shown. Diagnoses, detailed de- scriptions, and illustrations are presented for each species and subspecies. Geographic and bathymetric distributions are given. Affini- ties are discussed, and conclusions concern- ing ranges of variation and their spatial distribution are based onmorphometric stud- ies and other characters. The development of the external genitalia through the juvenile stage and the size range at which each taxon reaches the subadult stage are presented. Many details of ecology and life history are critically summarized and reviewed. A brief appraisal of the commercial importance of each form is also ;.
