Gammaridea was one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. In a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genera, divided among around 125 families. [1] That concept of Gammaridea included almost all freshwater amphipods, while most of the members still were marine.
The group is however considered paraphyletic, and was deconstructed in a series of papers by the amphipod taxonomists James K. Lowry and Alan A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea. [2] Further, in 2013 another large suborder Senticaudata was established, which would encompass much of the original Gammaridea, particularly its freshwater families, and into which also the Corophiidea was merged. [3] [4] The remaining 85 Gammaridea families, of superfamilies Liljeborgioidea, Lysianassoidea and Eusiroidea were rearranged to the new suborder Amphilochoidea in the final subordinal revision (2017), which no longer recognizes Gammaridea as a taxon.
