We assess the phylogenetic position of Siboglinidae (previously known as the phyla Pogonophora and Vestimentifera, but now referred to Annelida) in parsimony analyses of 1100 bp from 18S rRNA, 320 bp from the D1 region of 28S rRNA, and 107 morphological characters, totaling 667 parsimony informative characters. The 34 terminal taxa, apart from six siboglinids, include polychaete members of Sabellida, Terbelliformia, Cirratuliformia and Spionida, plus two Aciculata polychaetes as outgroups. Our results contradict most recent hypotheses in showing a sistergroup relationship between Siboglinidae and Oweniidae, and in that the latter taxon is not a member of Sabellida. Furthermore, our results indicate that Sabellariidae is not closely related to Sabellida, that Serpulidae may be nested within Sabellidae, and that Alvinellidae is nested within Ampharetidae.
我们在简约分析中评估了西伯加虫科（以前称为须腕动物门和前庭虫门，但现在归为环节动物门）的系统发育位置，分析涉及来自18S rRNA的1100 bp、来自28S rRNA D1区域的320 bp以及107个形态学特征，共计667个简约信息特征。除了6个西伯加虫科物种外，34个终端分类单元包括缨鳃虫目、叶须虫目、盘管虫目和多毛纲矶沙蚕目的多毛纲成员，另外还有两个针虫目多毛纲物种作为外类群。我们的结果与最近的大多数假说相矛盾，显示出西伯加虫科和欧文虫科之间为姐妹群关系，且后一个分类单元不是缨鳃虫目的成员。此外，我们的结果表明，缨鳃蚕科与缨鳃虫目没有密切关系，螺旋虫科可能嵌套在缨鳃虫科内，而艾氏虫科嵌套在蛰龙介科内。
