Valuable efforts have been made to describe the diversity of Syllidae Grube, 1850 in Brazilian waters, but only recently, taxonomic accounts of the family from oceanic islands began to be published. Here we reported five species of Exogone Ørsted, 1845 from Rocas Atoll, Fernando de Noronha and Trindade Islands. Exogone rocassp. nov. is described and Exogone simplex Hartmann-Schröder, 1960 (described and illustrated), Exogone africana Hartmann-Schröder, 1974, Exogone breviantennata Hartmann-Schröder, 1959, and Exogone naidinoides Westheide, 1974 are reported for the first time from Brazilian oceanic islands. Finally, we make considerations about the use of only morphology to identify these species, the doubts on the species records and the possible presence of sibling species under their currently reported distribution range.

来自巴西大洋洲的ExogoneØrsted,1845年(Annelida:Syllidae:Exogoninae),描述了一个新物种,并指出了该属中可能存在的隐藏多样性

为了描述1850年Syllidae Grube在巴西水域的多样性做出了巨大的努力,但直到最近,才开始发表有关海洋岛屿的家庭分类学资料。在这里,我们从Rocas Atoll,Fernando de Noronha和Trindade群岛报告了5种ExogoneØrsted,1845年。Exogone rocas sp。十一月 描述了Exogone simplexHartmann -Schröder,1960年(描述和说明),Exogone africanaHartmann -Schröder,1974年,Exogone breviantennataHartmann -Schröder,1959年和Exogone naidinoides1974年,Westheide首次报道来自巴西的海洋岛屿。最后,我们考虑使用仅形态学来识别这些物种,对物种记录的怀疑以及在其当前报告的分布范围内可能存在的同胞物种。
