摘要:

蛰龙介亚目（Terebellomorpha）营管栖生活，其形态和栖息环境多样，从海滨至深海均有分布，尤其在潮间带和近岸环境蛰龙介种类异常繁多，地域性分布明显，是海洋底栖生态系统的重要组成成分。因系统演化的复杂性和分类系统的混乱造成大量属的并系和多系现象，使得蛰龙介亚目成为多毛类研究中难度较大的类群。中国海域蛰龙介亚目尚缺乏系统分类学研究，在渤、黄、东、南各海区的分布和区系特点鲜为人知。因此，有必要进行全面系统的分类学研究，在此基础上建立分子生物学和形态学证据相互支持的、更加接近自然演化历史的分类系统。

Abstract:

The suborder Terebellomorpha is a large group in the class Polychaeta of Annelida. These organisms are usually tubicolous, marine living, distributed from the seashore to the deep sea, with a high diversity of morphology and habitats. The species diversity is high in intertidal zone and shallow waters, with many endemic species. This suborder is an important benthic annelid group that plays a vital role in marine ecosystems and biodiversity. Because of their variable morphology, complicated habitats, and many complex genera, studying their taxonomy and phylogeny is challenging. The knowledge of their taxonomy, phylogeny, and faunal characteristics from the China seas is poor. This study aims to approach the phylogenetic relationship of the subgroup Terebellomorpha based on a systematic study of its fauna from the China seas and establish a more natural system.
