摘要

夏岛是深海绿足动物科（环节动物）的一个属，其特征是有许多分叉的毛纲。人们对它知之甚少，只有三个物种生活在化学合成栖息地的双壳类动物的地幔腔中。本文通过对南海海马冷渗漏标本的形态和分子系统发育综合分析，对南海夏岛（Natsushima nanhaiensis n. sp.）进行了描述。在形态学上，新种可以从神经足钩和分叉毛羽的形状和数量、副足的形状和长背卷毛等方面与同属种区分开来。基于线粒体COI和16S rRNA基因序列的序列比较和系统发育分析支持了Natsushima nanhaiensis n.sp .在Natsushima的位置及其作为独特物种的地位。本文还给出了夏岛的物种分类表，并对其生物地理学进行了讨论。

A New Species of Natsushima (Annelida: Chrysopetalidae) Living in the Mantle Cavity of a Deep-Sea Solemyid Clam.

Natsushima is a genus of deep-sea Chrysopetalidae (Annelida) characterized by numerous bifurcate chaetae. It is poorly known, with three species living in the mantle cavity of bivalves in chemosynthetic habitats. Here we describe Natsushima nanhaiensis n. sp. based on an integrative morphological and molecular phylogenetic analysis of specimens collected from the Haima cold seep in the South China Sea. Morphologically, the new species can be distinguished from its congeneric species by the shape and number of the neuropodial hooks and bifurcate chaetae, the shape of the parapodia, and the long dorsal cirri. Sequence comparison and phylogenetic analysis based on the mitochondrial COI and 16S rRNA gene sequences supported the placement of Natsushima nanhaiensis n. sp. in Natsushima and its status as a distinct species. We also present a key to species of Natsushima and discuss their biogeography.
