Supplementary material for Teixeira et al. 2025 (Perinereis cultrifera/rullieri cryptic complex) published in Invertebrate Systematics

Supplementary data and allignments (COI; 16S; 28S; concatenated) for for the work entitled: "A sea of worms: the striking cases of the European Perinereis cultrifera and P. rullieri (Annelida: Nereididae) species complexes, with description of 13 new species", published in Invertebrate SystematicsShort Summary:Annelids have been proving to be a substantial fraction of cryptic biodiversity, an issue that is revealing itself more widespread and frequent than previously thought.Perinereis cultrifera is commonly used as a model species, but the possibility of multiple unreported and undescribed cryptic species may compromise the accuracy and the interpretation of scientific data.Integrative taxonomy exposed overlooked morphological traits, with 18 different European Perinereis lineages uncovered, 13 formally described.The molecular data and respective taxonomic curation from this study can contribute for a wide range of analysis from metabarcoding, to complementing species identification, conservation efforts or even in large scale biomonitoring projects.

本数据集为发表于《无脊椎动物系统学》（Invertebrate Systematics）的论文《蠕虫之海：欧洲镰叶围沙蚕（Perinereis cultrifera）与P. rullieri（环节动物门：沙蚕科（Nereididae））物种复合群的显著案例，并记述13个新种》的补充数据与序列联配（细胞色素c氧化酶亚基I（Cytochrome c oxidase subunit I，简称COI）；16S核糖体RNA基因（16S rRNA）；28S核糖体RNA基因（28S rRNA）；串联序列）。
简短摘要：环节动物已被证实是隐存生物多样性的重要组成部分，该现象的分布广度与出现频率均超出此前学界认知。镰叶围沙蚕（Perinereis cultrifera）常被用作模式研究物种，但存在多个未被报道、未正式描述的隐存物种的可能性，或将影响科学数据的准确性与解读可靠性。本研究通过整合分类学手段揭示了此前被忽视的形态特征，共发现18个欧洲围沙蚕演化支，其中13个已完成正式记述。本研究产生的分子数据及对应的分类学编目成果，可广泛应用于宏条形码（metabarcoding）分析、物种鉴定辅助、物种保护工作，乃至大规模生物监测项目。
