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 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 and gene sequences supported the placement of n. sp. in and its status as a distinct species. We also present a key to species of and discuss their biogeography.
是深海叶须虫科（环节动物门）的一个属，其特征是有许多分叉的刚毛。它鲜为人知，有三个物种生活在化学合成栖息地的双壳类动物的外套腔中。在这里，我们基于对从中国南海海马冷泉采集的标本进行的综合形态学和分子系统发育分析，描述了新物种。在形态上，新物种可以通过神经足钩和分叉刚毛的形状和数量、疣足的形状以及长的背触须与同属物种区分开来。基于线粒体和基因序列的序列比较和系统发育分析支持新物种在属内的位置及其作为一个独特物种的地位。我们还提供了该属物种的检索表并讨论了它们的生物地理学。
