Abstract

The family Eurytheneidae Stoddart & Lowry, 2004 is monotypic, including only the genus Eurythenes Smith, 1882, which is composed by Meso- and benthopelagic amphipods, with large vertical distribution in water column and can be reach depths of 5000 m, especially in muddy bottoms, in association with the great offer of organic matter in deep environments. Eurythenes is represented by nine species, with a cosmopolitan distribution, occurring in all oceans and covering high latitudes. However, in Atlantic Ocean, only five species are reported: Eurythenes obesus (Chevreux, 1905), E. magellanicus (H. Milne Edwards, 1848) as [= E. gryllus (Lichtenstein in Mandt, 1822)], E. maldoror d'Udekem d'Acoz & Havermans, 2015, E. sigmiferus d'Udekem d'Acoz & Havermans, 2015 and E. thurstoni Stoddart & Lowry, 2004, being the E. obesus reported only from the States of Rio de Janeiro and Bahia in Brazilian waters. In this study, we recorded the presence of E. obesus in Northeast of Brazil at seamounts (Fernando de Noronha Chain – off Rocas Atoll) and off the state of Rio Grande do Norte. This record brings a new observation of E. obesus from Brazil and increases knowledge on the deep crustaceans from the northeastern Brazil.

Abstract <p>fam&iacute;lia Eurytheneidae Stoddart &amp; Lowry, 2004 &eacute; monot&iacute;pica, incluindo apenas o g&ecirc;nero Eurythenes Smith, 1882, o qual &eacute; composto por anf&iacute;podas Meso e Batipel&aacute;gicos, com larga distribui&ccedil;&atilde;o vertical na coluna da &aacute;gua e podendo alcan&ccedil;ar profundidades de 5000 m, especialmente em fundos lamosos, em associa&ccedil;&atilde;o com a grande oferta de mat&eacute;ria org&acirc;nica em ambientes profundos. Eurythenes &eacute; representada por nove esp&eacute;cies, com distribui&ccedil;&atilde;o cosmopolita, ocorrendo em todos os oceanos e cobrindo altas latitudes. Contudo, no oceano Atl&acirc;ntico, apenas cinco esp&eacute;cies s&atilde;o reportadas: Eurythenes obesus (Chevreux, 1905), E. magellanicus (H. Milne Edwards, 1848) como [= E. gryllus (Lichtenstein in Mandt, 1822)], E. maldoror d&#39;Udekem d&#39;Acoz &amp; Havermans, 2015, E. sigmiferus d&#39;Udekem d&#39;Acoz &amp; Havermans, 2015 e E. thurstoni Stoddart &amp; Lowry, 2004, sendo o E. obesus reportado apenas para os Estados do Rio de Janeiro e Bahia em &aacute;guas Brasileiras. Neste estudo, nos registramos a presen&ccedil;a de E. obesus para os montes submarinos (Cadeia de Fernando de Noronha- fora do Atol das Rocas) e ao largo do Rio Grande do Norte, ambas localizadas no nordeste do Brasil. Esse registro tr&aacute;s uma nova observa&ccedil;&atilde;o do E. obesus para o Brasil e aumenta o conhecimento sobre crust&aacute;ceos profundos para o nordeste do Brasil</p>
