A new species of (Annelida: Serpulidae) is described based on specimens collected at the coastal Shonan area of Sagami Bay and the adjacent areas of Honshu, Japan. forms large aggregations in the intertidal rocky zone of warm-temperate Japanese shores. This species was referred to as (Baird, 1864) until the monotypic genus was synonymized with . This new species is formally described based on morphologically distinct Japanese specimens with supporting DNA sequence data. The calcareous opercular endplate of lacks a distinct talon, but some specimens have a slight rounded swelling on the endplate underside, while in other species of the complex a talon is present, usually extended, and with bulges. We examined sub-fossil tube aggregations of the new species and suggest that such aggregation stranded ashore is a good indicator of vertical land movements (uplift and subsidence) resulting from past events, such as earthquakes, in Honshu, Japan.
基于在日本相模湾湘南沿海地区和本州岛相邻区域采集的标本，描述了一种新的（环节动物门：龙介虫科）物种。该物种在日本暖温带海岸的潮间带岩石区形成大型群体。在单型属与合并之前，该物种被称为（贝尔德，1864年）。基于形态上有明显差异的日本标本以及支持性的DNA序列数据，正式描述了这个新物种。该物种的钙质鳃盖终板没有明显的爪，但有些标本在终板下侧有轻微的圆形肿胀，而在该类群的其他物种中存在爪，通常是延长的且有凸起。我们检查了新物种的亚化石管聚集体，并表明这种搁浅在岸上的聚集体是日本本州过去诸如地震等事件导致的垂直陆地运动（隆升和沉降）的良好指标。
