The monophyly of Sabellidae, the phylogenetic relationships of its lineages, and the composition of Sabellida have been debated for many decades. Most studies on sabellid phylogeny have focused on morphological features but little DNA work has been published to date. We performed analyses using maximum-parsimony methods that included 36 sabellids and members of previously related taxa. We integrated morphological and DNA sequence data to resolve relationships at different hierarchical levels (135 morphological features, fragments of the nuclear ribosomal RNA genes 18S and 28S, and the mitochondrial gene 16S). The results indicate the monophyly of Sabellida, including Sabellidae and Serpulidae. Monophyly of Fabriciinae and Serpulidae is assessed and the two groups are recovered as sister taxa, but with weak support. There is no significant support for the monophyly of Sabellinae. Relationships between members of the Sabellidae are still partially unresolved due to incongruence between partitions and low support for most clades. The evolution and transformation of certain characters within Sabellidae is explored. © The Willi Hennig Society 2010.
几十年来，缨鳃虫科的单系性、其谱系的系统发育关系以及缨鳃虫目的组成一直存在争议。大多数关于缨鳃虫系统发育的研究都集中在形态特征上，但迄今为止，很少有关于DNA的研究发表。我们使用最大简约法进行了分析，该分析包括36种缨鳃虫以及先前相关类群的成员。我们整合了形态学和DNA序列数据，以解析不同层次水平上的关系（135个形态特征、核糖体RNA基因18S和28S的片段以及线粒体基因16S）。结果表明缨鳃虫目的单系性，包括缨鳃虫科和龙介虫科。对法布里西缨虫亚科和龙介虫科的单系性进行了评估，这两个类群被确定为姐妹类群，但支持力度较弱。没有显著证据支持缨鳃虫亚科的单系性。由于不同分区之间存在不一致且大多数分支的支持度较低，缨鳃虫科成员之间的关系仍部分未得到解决。本文还探讨了缨鳃虫科内某些特征的进化和转变。© 威利·亨尼希协会2010年。
