根据在日本千叶县鸭川市采集的标本，描述了一种新的海洋穿囊湖沼藻。粗沼螺Limnoria aspera sp. nov.与无颚须类的其他种共享一退化的颚须为刚毛，摄食藻类，以及颚足类的棍棒状上足。L. asperasp. nov.在形态上与同属种的不同之处在于其具有次足甲和pleonite 5和pleotelson的独特隆线。我们描述了线粒体COI基因和核28 S rDNA基因的序列。L. aspera sp. nov.与其他日本种的COI序列在p-距离上相差14.2-18.0%。furca和L.永台。
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 14.2–18.0% in p-distance based on COI sequences from other Japanese species, L. furca and L. nagatai.
