Marenzelleria Mesnil, 1896 is a small group of spionid polychaetes comprising five valid species, all of which appear similar to each other. The identification of worms based on morphological features is often confusing, and thus molecular data have been suggested as providing crucial additional diagnostic characters. Here we summarize and map available records of M. viridis (Verrill, 1873) worldwide, and, based on the analysis of fragment sequences of COI, 16S, 18S, 28S and Histone 3, report this species for the first time from Norway. We also summarize and map the records of Marenzelleria from North America, distinguishing those based on morphology and molecular data. We report new records for Marenzelleria sp. from Baffin Is., Nunavut, Canada, and for M. neglecta Sikorski Bick, 2004 from Washington, USA.
Marenzelleria Mesnil，1896 年是一个由五个有效物种组成的小型磷虾多毛纲动物群，它们彼此相似。基于形态特征的蠕虫鉴定通常令人困惑，因此分子数据被认为提供了关键的附加诊断特征。在这里，我们总结并绘制了全球范围内 M. viridis（Verrill，1873）的现有记录，并基于 COI、16S、18S、28S 和组蛋白 3 片段序列的分析，首次从挪威报告了该物种。我们还总结并绘制了来自北美的 Marenzelleria 记录，根据形态和分子数据对其进行区分。我们报告了来自加拿大努纳武特巴芬岛的 Marenzelleria sp. 的新记录，以及来自美国华盛顿的 M. neglecta Sikorski Bick，2004 的新记录。
