摘要

在澳大利亚东海岸的深水中，描述了七个Circuratulidae新种。样本是在2017年5月/6月RV调查员航行IN2017_V03的一部分中收集的，使用布伦克雪橇和0.25 m2箱芯。本研究中报告的样本深度从约2100米的下陆坡到4170米的深海。这些采集提供了第一批在澳大利亚附近深水中描述的卷层多毛类。卷层虫科的新种有Aphelochaeta属（2）、Chaetocirratulus属（2、Chaetozone属（2和Kirkegaardia属（1））。每一个新物种都与其已知的同类进行了比较和对比。综述和讨论了3000米及以上深海中已知的双柱轮藻科。

New species of Cirratulidae (Annelida) from continental slope and abyssal depths off eastern Australia

Seven new species of Cirratulidae are described from deep waters off the east coast of Australia. Samples were collected as part of the RV Investigator voyage IN2017_V03 in May/June 2017 using a Brenke sledge and 0.25 m2 box core. Sample depths reported in the present study were from the lower continental slope of about 2100 m to abyssal depths up to 4170 m. These collections provide the first cirratulid polychaetes to be described from deep water off Australia. The new species of Cirratulidae are in the genera Aphelochaeta (2), Chaetocirratulus (2), Chaetozone (2), and Kirkegaardia (1). Each of the new species is compared and contrasted with their known congeners. The bitentaculate Cirratulidae known from abyssal depths of 3000 m and greater are reviewed and discussed.
