title: Redescription ofDynoides elegans(Boone, 1923) (Crustacea, Isopoda, Sphaeromatidae) from the north-eastern Pacific.
abstract: Dynoides elegans(Boone, 1923) from southern California is reviewed, redescribed, and figured. The original species description did not include figures, making it difficult to attribute individuals to the species.Dynoides saldanaiCarvacho and Haasmann, 1984 andDynoides crenulatusCarvacho & Haasman, 1984 from the Pacific Coast of Mexico andDynoides brevicornisKussakin & Malyutina, 1987, from Furugelm Island, Peter the Great Gulf in the Sea of Japan, appear morphologically more similar to each other than to western Pacific species. A large pleonal process is present in about half of theDynoidesspecies, but is absent in this north-eastern Pacific clade and the north-western PacificDynoides brevicornisandDynoides brevispina.Dynoides dentisinusShen, 1929 possess a large pleonal spine. It is known from China, Japan, and Korea and is introduced in San Francisco Bay; it can be easily distinguished fromDynoides elegansby the presence of a pleonal process in the former. A key to the Pacific West CoastDynoidesis provided.
