Abstract

Taxonomy plays a central role in biological sciences. It provides a communication system for scientists as it aims to enable correct identification of the studied organisms. As a consequence, species descriptions should seek to include as much available information as possible at species level to follow an integrative concept of 'taxonomics'. Here, we describe the cryptic species Epimeria frankei sp. nov. from the North Sea, and also redescribe its sister species, Epimeria cornigera. The morphological information obtained is substantiated by DNA barcodes and complete nuclear 18S rRNA gene sequences. In addition, we provide, for the first time, full mitochondrial genome data as part of a metazoan species description for a holotype, as well as the neotype. This study represents the first successful implementation of the recently proposed concept of taxonomics, using data from high-throughput technologies for integrative taxonomic studies, allowing the highest level of confidence for both biodiversity and ecological research.

摘要

分类学在生物科学中起着核心作用。它为科学家提供了一种交流系统，因为它旨在实现对所研究生物的正确识别。因此，物种描述应该力求在物种水平上包含尽可能多的可用信息，以遵循“分类学”的综合概念。在这里，我们描述了来自北海的隐种 Epimeria frankei sp. nov.，并重新描述了其姊妹种 Epimeria cornigera。所获得的形态信息通过 DNA 条码和完整的核 18S rRNA 基因序列得到证实。此外，我们还首次提供了完整的线粒体基因组数据，作为模式标本和新标本的后生动物物种描述的一部分。这项研究代表了最近提出的分类学概念的首次成功实施，利用高通量技术的数据进行综合分类学研究，为生物多样性和生态研究提供了最高水平的置信度。
