Dorvilleidae is a diverse group of annelids found in many marine environments and also commonly associated with chemosynthetic habitats. One dorvilleid genus, Parougia, currently has 11 described species, of which two are found at vents or seeps: Parougia wolfi and Parougia oregonensis. Eight new Parougia species are recognised and described in this study from collections in the Pacific Ocean, all from whale-falls, hydrothermal vents, or methane seeps at ~600-m depth or greater. The specimens were studied using morphology and phylogenetic analyses of DNA sequences from mitochondrial (cytochrome c oxidase subunit I, 16S rRNA, and cytochrome b) and nuclear (18S rRNA and histone 3) genes. Six sympatric Parougia spp. were found at Hydrate Ridge, Oregon, while three of the Parougia species occurred at different types of chemosynthetic habitats. Two new species were found over wide geographical and bathymetric ranges. Another dorvilleid genus, Ophryotrocha, has previously been highlighted as diversifying in the deep-sea environment. Our results document the hitherto unknown diversity of another dorvilleid genus, Parougia, at various chemosynthetic environments. http://zoobank.org/urn:lsid:zoobank.org:pub:EC7EBBEA-2FB5-43D6-BE53-1A468B541A5C

太平洋喷口、甲烷渗漏和鲸落鹦鹉科（Dorvilleidae：Annelida）的系统发育、生物地理学和系统学，有八个新物种

Dorvilleidae 是在许多海洋环境中发现的多种环节动物，通常也与化学合成栖息地有关。一个 dorvilleid 属 Parougia 目前有 11 个被描述的物种，其中两个在喷口或渗漏处被发现：Parougia wolfi 和 Parougia oregonensis。本研究从太平洋的收藏中识别和描述了八种新的 Parougia 物种，所有物种都来自鲸鱼瀑布、热液喷口或约 600 米或更深的甲烷渗漏。使用来自线粒体（细胞色素 c 氧化酶亚基 I、16S rRNA 和细胞色素 b）和核（18S rRNA 和组蛋白 3）基因的 DNA 序列的形态学和系统发育分析来研究标本。六个同域 Parougia spp。发现于俄勒冈州的 Hydrate Ridge，而三种 Parougia 物种出现在不同类型的化学合成栖息地。在广泛的地理和水深范围内发现了两个新物种。另一个 dorvilleid 属，Ophryotrocha，以前曾被强调在深海环境中多样化。我们的结果记录了在各种化学合成环境中另一个 dorvilleid 属 Parougia 迄今为止未知的多样性。http://zoobank.org/urn:lsid:zoobank.org:pub:EC7EBBEA-2FB5-43D6-BE53-1A468B541A5C
