A new marine Sargassum-boring species of Limnoria (Limnoriidae) is described on the basis of specimens obtained at Kamogawa-shi, Chiba Prefecture, Japan. Limnoria aspera sp. nov. shares a reduced mandibular palp to a seta, algal-feeding, and the clavate shaped epipod of the maxilliped with the other species of non-mandibular-palp group. L. aspera sp. nov. differs morphologically from the congeneric species by secondary unguis of pereopods and unique carinae of pleonite 5 and pleotelson. We describe the sequences of the mitochondrial COI gene and the nuclear 28S rDNA gene. L. aspera sp. nov. differs by 14.218.0% in p-distance based on COI sequences from other Japanese species, L. furca and L. nagatai.
本文基于在日本千叶县Kamogawa-shi 获得的标本，描述了一种新的海洋马尾藻钻孔种 Limnoria（Limnoriidae）。Limnoria aspera sp. nov. 具有简化的下颌触须，以刚毛为食，以及大型颚足的棒状附肢，与其他非下颌触须组的物种相同。Limnoria aspera sp. nov. 在形态上与同属种的区别在于，它的游泳足的次生爪和独特的 5 节体节和pleotelson 的嵴。我们描述了线粒体 COI 基因和核 28S rDNA 基因的序列。Limnoria aspera sp. nov. 在 COI 序列上与其他日本种 Limnoria furca 和 L. nagatai 相比，差异为 14.218.0%。
