In Australia, the deep-water (bathyal and abyssal) benthic invertebrate fauna is poorly known in comparison with that of shallow (subtidal and shelf) habitats. Benthic fauna from the deep eastern Australian margin was sampled systematically for the first time during 2017 RV 'Investigator' voyage 'Sampling the Abyss'. Box core, Brenke sledge, and beam trawl samples were collected at one-degree intervals from Tasmania, 42°S, to southern Queensland, 24°S, from 900 to 4800 m depth. Annelids collected were identified by taxonomic experts on individual families around the world. A complete list of all identified species is presented, accompanied with brief morphological diagnoses, taxonomic remarks, and colour images. A total of more than 6000 annelid specimens consisting of 50 families (47 Polychaeta, one Echiura, two Sipuncula) and 214 species were recovered. Twenty-seven species were given valid names, 45 were assigned the qualifier cf., 87 the qualifier sp., and 55 species were considered new to science. Geographical ranges of 16 morphospecies extended along the eastern Australian margin to the Great Australian Bight, South Australia; however, these ranges need to be confirmed with genetic data. This work providing critical baseline biodiversity data on an important group of benthic invertebrates from a virtually unknown region of the world's ocean will act as a springboard for future taxonomic and biogeographic studies in the area.
在澳大利亚，与浅海（潮下带和陆架）栖息地相比，深水（半深海和深海）底栖无脊椎动物区系鲜为人知。2017年“调查者号”（RV 'Investigator'）“深渊采样”航次期间，首次对澳大利亚东部深海底栖动物区系进行了系统采样。在从塔斯马尼亚（南纬42°）到昆士兰南部（南纬24°）、深度从900米至4800米的区域，每隔一度采集箱式岩心、布伦克拖网和桁拖网样本。所采集的环节动物由世界各地各分类科的专家进行鉴定。列出了所有已鉴定物种的完整清单，并附有简要的形态学诊断、分类学说明和彩色图像。共采集到6000多个环节动物标本，分属50个科（47个多毛纲、1个螠虫纲、2个星虫纲）和214个物种。27个物种被赋予有效名称，45个被指定为cf.（注：相似种），87个被指定为sp.（注：待定种），55个物种被认为是科学上新发现的。16个形态种的地理分布范围沿澳大利亚东部边缘延伸至南澳大利亚的大澳大利亚湾；然而，这些分布范围需要通过基因数据来确认。这项工作提供了关于世界海洋一个几乎未知区域重要底栖无脊椎动物类群的关键基线生物多样性数据，将成为该地区未来分类学和生物地理学研究的跳板。
