A new genus and two new species are described based on material collected from the mesophotic coral ecosystems of the U.S. Caribbean. The new genus Borikenella can be distinguished from other related genera such as Pseudaeginella, Paradeutella, Aciconula and Deutella by the combination of the following characters: pereopods 3 and 4 three-articulate, pereopods 5-7 six-articulate, mandible molar present, palp of the mandible with a setal formula 1-x-0, abdomen without appendages. The new species Liropus gurui, can be distinguished from the closely related L. japonicus mainly by the lack of anteroventral margin extended forward in pereonite 3, the lack of cleft and serration in the propodus of gnathopod 2, the longer pereopod 3 and the larger abdominal appendages.
基于从美国加勒比地区的中光层珊瑚生态系统收集的材料，描述了一个新属和两个新物种。新属Borikenella可通过以下特征组合与其他相关属如Pseudaeginella、Paradeutella、Aciconula和Deutella区分开来：第3和第4步足分三节，第5 - 7步足分六节，有下颌磨齿，下颌触须的刚毛公式为1 - x - 0，腹部无附肢。新物种Liropus gurui与近缘种日本Liropus japonicus的主要区别在于第3腹节的前腹缘不向前延伸，第2颚足的螯不具裂和锯齿，第3步足较长，腹部附肢较大。
