An Annotated Checklist and Bibliography of Deep-Water Isopods and Decapod Crustaceans from Chile, Including the Submarine Ridge Salas y Gomez and Nazca Plates

A list of deep-water species (> 200 m depth) of isopods and decapod crustaceans from off Chile is presented, including the areas of South America, the Antarctic, and offshore islands. Also included are the species that were collected in the Nazca and Sala y Gomez seamounts areas during the ex-Soviet Union Expeditions in the 1970s (1973–1978), although not all species found during these expeditions have not yet been recorded for Chilean waters but in international waters. Isopods were represented by nine species only, four in the Peru-Chile Trench, three off Chiloe, and two in the Magellan Strait. In the case of the decapods, 143 species have been reported in Chile, mostly within the suborder Pleocyemata (134 spp.). These 143 species are grouped in 42 families, 5 of these in the Dendrobranchiata.
