摘要

利用形态学和分子（细胞色素氧化酶亚单位 I（COI）基因）数据，描述了马来西亚半岛东海岸登嘉楼州的四个马菲莎新种。这些物种属于 Marphysa 的不同类群：属于 A 组（Mossambica），Marphysa merchangensissp.nov.和 Marphysa setiuensesp.nov.属于 B 组（Sanguinea），Marphysa ibaiensissp.nov.属于 E 组（Gravelyi）。Marphysa kertehensissp.nov.的特征是只有肢状链节，没有近圆形钩，有三种栉状链节，包括宽而粗的等齿和短而细的内齿，栉状支节有多达九根支丝。Marphysa merchangensissp.nov.的特征是有眼睛、不确定的近圆形钩、四种栉状链器（包括宽厚的等齿栉状链器具五枚长而粗的内齿）和栉状枝节具多达六根枝丝。Marphysa setiuensesp. nov.主要具有不识别的近圆形钩（在几个后方的链格上具有双齿），四种栉状链格，包括宽厚的无齿栉状链格（具有七个又粗又长的内齿），以及栉状支节（具有多达五个支丝）。Marphysa ibaiensissp. nov.具有全部双叉近圆形钩，五种栉状链器，包括具有 12 个短而细长内齿的异齿，以及具有多达 8 个支丝的栉状支节。这些基于形态学的新种命名得到了分子数据的充分支持。每个物种的栖息地描述也包括在内。

Four new species of Marphysa (Annelida, Eunicida, Eunicidae) from the east coast of Peninsular Malaysia

Four new species of Marphysa are described from Terengganu state on the east coast of Peninsular Malaysia, using morphological and molecular (cytochrome oxidase subunit I (COI) gene) data. These species belong to different groups of Marphysa: Marphysa kertehensissp. nov. belongs to Group A (Mossambica), Marphysa merchangensissp. nov. and Marphysa setiuensesp. nov. belong to Group B (Sanguinea) and Marphysa ibaiensissp. nov. belongs to Group E (Gravelyi). Marphysa kertehensissp. nov. is characterised by having only limbate chaetae, absence of subacicular hooks, three types of pectinate chaetae including wide, thick isodont with short and slender inner teeth, and pectinate branchiae with up to nine branchial filaments. Marphysa merchangensissp. nov. is characterised by the presence of eyes, unidentate subacicular hooks, four types of pectinate chaetae including wide, thick anodont pectinate chaetae with five long and thick inner teeth, and pectinate branchiae with up to six branchial filaments. Marphysa setiuensesp. nov. has mostly unidentate subacicular hooks (bidentate on several posterior chaetigers), four types of pectinate chaetae including wide, thick anodont pectinate chaetae with seven thick and long inner teeth, and pectinate branchiae with up to five branchial filaments. Marphysa ibaiensissp. nov. has bidentate subacicular hooks throughout, five types of pectinate chaetae, including a heterodont with 12 short and slender inner teeth, and pectinate branchiae with up to eight branchial filaments. The designation of these new species based on morphology is fully supported by molecular data. Habitat descriptions of each species are also included.

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.
