摘要

摘要带状蠕虫（线虫门）在世界各地的海洋中都有发现；然而，只有少数栖息在陆地、半陆地和淡水环境中。在我们的研究中，我们描述了Acteonemetes orientalis sp.nov.，一个Plectonemertidae Gibson的新种，1990年，也是在日本发现的第一个Plectenemertid。该物种是在日本海沿岸的超海岸带发现的，在那里很少有奈美特氏线虫的报道，它们栖息在岩石、消浪混凝土块、落叶和鱼群下。基于两个线粒体（16S rRNA和细胞色素c氧化酶亚基I）和两个核基因标记（18S rRNA、28S rRNA）的多基因座系统发育分析表明，A.orientalis sp.nov.与收集自佛罗里达州的细端单体鱼（Leptonemertes cf.chalicophora）形成了一个分支。尽管东方A.orientalis sp.nov.的外部和内部形态与一般诊断基本一致，但该物种的不同之处在于长鼻较大。根据分子和形态学数据，我们建议通过排除长鼻大小来修正Acteonemertes的诊断。ZooBank:urn:lsid:ZooBank.org：pub:BBBBE9549-5DCE-424F-9A39-930F8243C28B

At the edge of the sea: the supralittoral nemertean, Acteonemertes orientalis sp. nov. (Nemertea: Eumonostilifera: Plectonemertidae) from Japan

Abstract. Ribbon worms (phylum Nemertea) are found in oceans worldwide; however, only a few inhabit terrestrial, semiterrestrial and freshwater environments. In our study, we describe Acteonemertes orientalis sp. nov., a new species of Plectonemertidae Gibson, 1990 and the first plectonemertid discovered in Japan. The species was found in the supralittoral zone, from which nemerteans have rarely been reported and inhabits areas under rocks, wave-dissipating concrete blocks, and fallen leaves and stocks, along the coast of the Sea of Japan. Multi-locus phylogenetic analyses based on two mitochondrial (16S rRNA and cytochrome c oxidase subunit I) and two nuclear gene markers (18S rRNA and 28S rRNA) revealed that A. orientalis sp. nov. formed a clade with Leptonemertes cf. chalicophora collected from Florida. Although the external and internal morphology of A. orientalis sp. nov. is largely consistent with the generic diagnosis, this species differs in having a large proboscis. Based on the molecular and morphological data, we propose to amend the diagnosis of Acteonemertes by excluding proboscis size. ZooBank: urn:lsid:zoobank.org:pub:BBBE9549-5DCE-424F-9A39-930F8243C28B

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
