AB - Abstract Descriptions, illustrations, synonymies and distributional data are provided for the eight species of Rocinela (Isopoda: Aegidae) now known from the tropical eastern Pacific, and for the temperate species R. angustata Richardson, 1904. A revised description of the genus is presented, as well as a key to all species known from the eastern Pacific (Alaska to Tierra del Fuego). Lectotypes are designated for three species: R. angustata, R. laticauda Hansen, 1897 and R. tuberculosa Richardson, 1898, and a neotype is designated for R. belliceps (Stimpson, 1864). One new species is described, R. wetzeri sp. nov. Rocinela hawaiiensis Richardson, 1903 is reported for the first time outside the Hawaiian Islands (from Guadalupe Island, Mexico). Our examination of material in this genus from various institutional collections indicates that specimens are often misidentified. Use of the mouth appendages or pleopods to characterize or identify species is unreliable as there is little interspecific variation in these characters. Useful characters are those of frontal margin and frontal lamina morphology, pereopodal armature (although this is somewhat polymorphic in most species), and the shape and armature of the uropods. Four species (R. angustata, R. laticauda, R. australis Schiödte & Meinert, 1879, and R. murilloi Brusca & Iverson, 1985) are very similar and easily confused, but they can be distinguished with the key provided. The most commonly collected species in the tropical eastern Pacific are R. murilloi, R. belliceps and R. signata Schiödte & Meinert, 1879; the former is a deep-water species, the latter two are shallow-water. Rocinela australis has not been reported since its original description, more than 110 years ago. Isopoda, Aegidae, Rocinela, taxonomy, marine, Pacific BARNARD , K. H. 1914 .
