<p><strong>Abstract.</strong> A study of the family Cytheruridae in Recent sediments from the coast of northern Rio de Janeiro State revealed the presence of four new species: (<i>Hemicytherura auriculata, Oculocytheropteron delicatum, Oculocytheropteron circumcostatum</i> and <i>Semicytherura caudata</i>,) and four previously described species (<i>Semicytherura rugosoreticulata</i> Whatley, Chadwick, Coxill &amp;amp; Toy, 1988, <i>Oculocytheropteron macropunctatum</i> Whatley, Chadwick, Coxill

A further two species <i>Cytheropteron</i> sp. and <i>Kangarina</i> sp. are left in open nomenclature due to paucity of the material. The ecology and distribution of the fauna suggest that the presence of many of these species, which also occur in colder waters off the coast of Uruguay and Argentina, is probably due to the upwelling of the South Atlantic Central Water in this area.</p>
