Abstract

ABSTRACT The study of marine annelids from oceanic islands has been problematic, especially because of the lack of infrastructure, or of easily accessible logistics for frequent expeditions. In this contribution, some specimens collected during the J.-L. Étienne Expedition to Clipperton Island in 2005, belonging to the families Hesionidae Grube, 1850 and Phyllodocidae Örsted, 1843 are newly described. Type material is deposited in the Muséum national d'Histoire naturelle, Paris, and a few others in El Colegio de la Frontera Sur, Chetumal. Hesionidae includes Psamathe charpyi n. sp. diagnosed by having eyes of similar size and neurochaetal blades 4-10 × longer than wide. In Phyllodocidae an assessment of the affinities within Phyllodoce Savigny in Lamarck, 1818 results in re-establishing its subgenera as distinct genera, and three species are newly described: Anaitides albengai n. sp., Nereiphylla etiennei n. sp., and Pterocirrus bouchardi n. sp. Anaitides albengai n. sp. is separated from more similar species by having the prostomium as long as wide, eyes ¼ as long as prostomial width, and basal pharynx region with 8-9 large papillae per row. Nereiphylla etiennei n. sp. differs from more similar species by having a rectangular prostomium, lateral antennae half as long as prostomial width, and ventral cirri barely longer than neurochaetal lobe. Pterocirrus bouchardi n. sp. separates from more similar species by having antennae of similar length, dorsal cirri tapered not distally constricted, and acicular lobes barely divergent. Keys are included for identifying all World species for each genus.

克利珀顿岛附着多毛类和叶序多毛类新种（环节动物，埃兰蒂亚）

摘要对海岛海洋环节动物的研究一直存在问题，尤其是因为缺乏基础设施，或者缺乏方便频繁探险的物流。在这篇文章中，对2005年J.-L.Étienne远征克利珀顿岛期间收集的一些标本进行了新的描述，这些标本属于赫西翁科Grube，1850年和PhyllodocidaeÖrsted，1843年。类型材料存放在巴黎国家自然历史博物馆（Muséum national d'Histoire naturelle），其他一些则存放在切图马尔的El Colegio de la Frontera Sur。Hesionidae包括Psamathecharpyi n.sp.，通过具有相似大小的眼睛和比宽长4-10倍的神经血管刀片来诊断。在Lamarck的Phyllodicae中，1818年对Phyllodice Savigny内部亲缘关系的评估导致将其亚属重新建立为不同的属，并新描述了三个物种：Anaitides albengai n.sp.、Nereiphylla etiennei n.sp.和Pterocirrus bouchardi n.sp.Anaitides albengai n.sp，眼睛的宽度是前列腺宽度的¼倍，咽部基底区每行有8-9个大乳头。Nereiphylla etiennei n.sp.与更相似的物种不同之处在于，它有一个矩形的前肢，侧触角是前肢宽度的一半长，腹侧卷须几乎不比神经血管叶长。bouchardi翼龙与更相似的物种的区别在于，它们有相似长度的触角，背部卷须渐缩而不向远端收缩，针状裂片几乎不分叉。包括用于识别每个属的所有世界物种的钥匙。
