Although polychaetes from the Bermuda Archipelago have been studied since the beginning of the twentieth century, syllids have been particularly neglected in this area, which is surprising considering this family is usually a dominant group in marine benthic ecosystems. To fill this knowledge gap, we have carried out an extensive analysis of Bermudan Syllidae, combining morphological and molecular data including four nuclear and mitochondrial markers (, , and ). We have identified and established the phylogenetic position of five new species, n. sp., n. sp., n. sp., n. sp. and n. sp., together with cf. . Overall, our results extend the knowledge on the diversity of Syllidae in Bermuda, increasing the number of species present in the area to 25. Our results also recover and as non-monophyletic genera, for which traditional diagnostic morphological features do not accurately reflect their evolutionary histories, and thus we propose that these groups should be reorganized based on molecular characters.
尽管自20世纪初以来就对百慕大群岛的多毛纲动物进行了研究，但在该地区，叶须虫科一直特别受到忽视，考虑到这个科通常是海洋底栖生态系统中的优势类群，这一点令人惊讶。为了填补这一知识空白，我们对百慕大叶须虫科进行了广泛分析，结合了形态学和分子数据，包括四个核标记和线粒体标记（、、和）。我们已经鉴定并确定了五个新物种的系统发育位置，即新物种、新物种、新物种、新物种和新物种，以及近似种。总体而言，我们的结果扩展了对百慕大叶须虫科多样性的认识，使该地区的物种数量增加到25种。我们的结果还发现和不是单系属，其传统的诊断形态特征不能准确反映它们的进化历史，因此我们建议应根据分子特征对这些类群进行重新组织。
