Abstract

Abstract Echiniscoididae are the only family of the clade Echiniscoidea residing in marine habitats. Their characteristic feature is the multiplication of claws on legs, commonly regarded as an adaptation to unstable tidal environment. Although DNA barcoding data indicated the presence of numerous unnamed candidate species within Echiniscoides about a decade ago, only recently have new species been formally described. In this paper, we present new genetic, morphological and morphometric data and establish five Echiniscoides species found in samples acquired from various tropical regions: Echiniscoides basalticus sp. nov. (Mauritius, Indian Ocean), Echiniscoides bufocephalus sp. nov. (Qatar, Indian Ocean), Echiniscoides lichenophilus sp. nov. (Dominican Republic, Atlantic Ocean), Echiniscoides musa sp. nov. (Brazil, Atlantic Ocean), and Echiniscoides trichosus sp. nov. (Rapa Nui, Pacific Ocean). We discuss the taxonomic importance of cuticular sculpturing in Echiniscoididae. Finally, we elevate all subspecies of Echiniscoides sigismundi to species level. The key to all echiniscoidids is provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:63154710-C3BA-402A-A11B-C211DAE59CAB

热带海洋异缓步动物新系(棘虫科)

摘要棘皮蝶科是棘皮蝶亚科中唯一一个生活在海洋栖息地的科。它们的特征是腿上爪子的繁殖，通常被认为是对不稳定潮汐环境的适应。尽管DNA条形码数据表明大约十年前在棘皮动物中存在许多未命名的候选物种，但直到最近才正式描述新物种。在本文中，我们提供了新的遗传、形态学和形态计量学数据，并建立了从不同热带地区采集的样本中发现的五种棘皮动物：基底棘皮动物（Echinicoides basticus sp.nov.）（毛里求斯，印度洋）、布头棘皮动物属（Echinocoides bufocephalus sp.nova.），musa Echinicoides sp.nov.（巴西，大西洋）和trichosus Echinocoides sp.nov.（Rapa Nui，太平洋）。我们讨论了棘皮动物科表皮雕刻在分类学上的重要性。最后，我们将棘皮动物的所有亚种提升到物种水平。提供了所有针剂的关键。http://www.zoobank.org/urn:lsid:zoobank.org:pub:63154710-C3BA-402A-A11B-c211dae59驾驶室

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.
