A Key to the Palaemonid Shrimp of the Eastern Pacific Region

Abstract

Since the publication of the keys in the monographic study of American <br /><br />palaemonid shrimp by Holthuis (1951, 1952), numerous range extensions have <br /><br />been found, two new genera and seven new species have been described, and a <br /><br />taxonomic revision has added three genera to the family in the eastern Pacific. <br /><br />An up-to-date annotated key is provided to the 48 eastern Pacific species.
