Black corals (Anthozoa: Antipatharia) are an anthozoan lineage in the class Hexacorallia that occur across a wide range of habitats from the tropics to the poles and from surface waters to depths deeper than 8000 m. A new species of black coral, , collected with a remotely operated vehicle 357 m deep off Puerto Rico is recognized in the family Aphanipathidae. The new species is characterized by very long and loosely coiled primary branches and up to 0.5 mm tall spines with as many as 40 or more small conical tubercles. A phylogeny composed of 13 taxa that are closely related to the new species was reconstructed from 793 nuclear loci to show their systematic relationships. Our study integrated morphological and genomic data to show that this new species is distinct from other species in the genus Furthermore, our results add to the growing knowledge of black coral diversity, while further demonstrating the need for exploration in deep waters of the Caribbean Sea.
黑珊瑚（珊瑚纲：角珊瑚目）是六放珊瑚亚纲中的一个珊瑚虫类群，分布于从热带到极地、从表层水域到深度超过8000米的广泛栖息地。在波多黎各近海357米深处，通过遥控潜水器采集到一种新的黑珊瑚，属于隐角珊瑚科。该新物种的特征是具有非常长且松散盘绕的初级分支以及高达0.5毫米的刺，刺上有多达40个或更多的小圆锥形瘤。从793个核基因座重建了一个由13个与该新物种密切相关的分类单元组成的系统发育树，以显示它们的系统关系。我们的研究整合了形态学和基因组数据，表明这个新物种与该属中的其他物种不同。此外，我们的研究结果增加了对黑珊瑚多样性的认识，同时进一步证明了对加勒比海深水区进行探索的必要性。
