Abstract

Four new species of Daylithos (Flabelligeridae, Annelida) are described, based on specimens collected from rocks and corals of Japan and Malaysia. Daylithos, contains one species, D. parmatus, currently reported from Japan. However, the specimens described in previous reports were unable to be located and thus deemed lost. Therefore, it was unclear whether the specimens described as D. parmatus in those studies were, indeed, the species. In Malaysia, D. parmatus has also been known as popular species from corals. The specimens collected from Langkawi (Malaysia) showed clearly different characters from D. parmatus and other congeners. In this study, we describe four new species, Daylithos japonicus, D. amamiensis, D. sugashimaensis and D. langkawiensis, based on newly-collected specimens from several part of Japan and Malaysia. These new species can be discriminated from other congeners by body colour, presence of eyes, shape of dorsal shield, length of caruncle and arrangement of neurochaetae. We have also provided mitochondrial cytochrome c oxidase subunit I sequences of the new species.

太平洋珊瑚虫和钻岩多毛纲四新种(节肢动物，节肢动物科)

根据从日本和马来西亚的岩石和珊瑚中收集的标本，描述了四种新的日石(flabelligeriae，环节动物)。日石，含一种，parmatus，最近报道自日本。然而，以前报告中描述的标本无法定位，因此被认为已经丢失。因此，在这些研究中被描述为parmatus的标本是否确实是该物种尚不清楚。在马来西亚，D. parmatus也被认为是珊瑚中受欢迎的物种。从兰卡威(马来西亚)采集的标本显示出与parmatus及其同系物明显不同的特征。本研究基于日本和马来西亚部分地区的新采集标本，描述了4个新种:日本日石(Daylithos japonicus)、D. amamiensis、D. sugashimaensis和D. langkawiensis。这些新物种可以通过身体颜色、眼睛的存在、背盾的形状、腕骨的长度和神经毛纲的排列来与其他同类区分开来。我们还提供了新种线粒体细胞色素c氧化酶亚基I序列。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
