SUMMARY:

Very little is known about the diversity of species of Amphipoda Latreille, 1816, for oceanic
islands in Brazil. This dissertation describes a new species of the genus Pariphinotus Kunkel,
1910, family Phliantidae Stebbing, 1899, which is distinguished from other similar species by
presenting the following characters: Pleopod 3 with two coupling setae to the peduncle, uropod
1, peduncle not exceeding the distal margin of telson and the latest with subacute distal margin.
This is the second species of the genus known from Brazil and the first recorded from the
Fernando de Noronha Archipelago. The first record of the circuntropical species Synopia
ultramarina Dana, 1853, is also made for the archipelago. Previously, this species was
registered in Brazilian waters only for the states of Bahia and Espírito Santo. However,
additional material was examined, in addition to Fernando de Noronha, also for the coast of the
states of Ceará and Pernambuco. Morphological variations were observed between populations,
based on the material studied and previous descriptions of the same species in the literature. In
addition to these two species, Cymadusa filosa Savigny,1816, of the family Ampithoidae
Boeck, 1871, Gibberosus myersi (McKinney, 1980), of the family Megaluropidae Thomas &
Barnard, 1986, and Mayerella sp., family Caprellidae Leach, 1814, are also registered for the
first time for the Archipelago of Fernando de Noronha. Finally, an additional record of the species Elasmopus longipropodus Senna & Souza-Filho, 2011, of the family Maeridae Krapp-Schickel, 2008, is the only one among the examined material previously known from the location. The material examined comes from the Fernando de Noronha Archipelago, state of Pernambuco, northeastern Brazil, and was collected by SCUBA diving, from rhodoliths beds, from the Ressureta channel, between Meio and Rata Islands. Additional material was collected off the coast of the state of Ceará, during environmental consultancies coordinated by Petrobras S. A., and off the coast of the state of Pernambuco, during the REVIZEE NE Project.
