Abstract

The swimming crabs (family Portunidae) are distributed worldwide and commonly inhabit estuaries, mangroves, reefs, shallow and the deep sea. Previously, 75 species and 19 genera in this family were known to Taiwan. Our study examined specimens in Taiwanese waters, including the islands, collected between 2016 and 2020 or deposited in museums. Through the cytochrome oxidase subunit I DNA barcode marker and morphological examination, 71 species were identified. The minimum interspecific distances were greater than 4.09%, except in two unresolved groups: Charybdis miles (De Haan, 1835) and Ch. sagamiensis Parisi, 1916, as well as Thranita pelsarti (Montgomery, 1931) and Thr. prymna (Herbst, 1803). In addition, 14 species belonging to nine genera were confirmed as new records to Taiwan, viz. Carupa ohashii Takeda, 1993, Lupocyclus inaequalis (Walker, 1887), Luu. tugelae Barnard, 1950, Lupocycloporus minutus (Shen, 1937), Monomia gladiator (Fabricius, 1798), M. lucida Koch & Ďuriš, 2018, Podophthalmus minabensis Sakai, 1961, Thalamita gatavakensis Nobili, 1906, Tha. spinifera Borradaile, 1902, Thalamitoides quadridens A. Milne-Edwards, 1869, Tho. tridens A. Milne-Edwards, 1869, Thr. cerasma (Wee & Ng, 1995), Thr. coeruleipes (Hombron & Jacquinot, 1846) and Xiphonectes tuberculosus (A. Milne-Edwards, 1861). This study thus raises the total number of Portunidae species in Taiwan to 89.

台湾游蟹(甲壳纲:短尾目:梭子蟹科)的DNA条形码多样性估算及14条新记录描述。

游泳蟹(蟹科)分布于世界各地，通常栖息于河口、红树林、珊瑚礁、浅海和深海。台湾已知该科19属75种。我们的研究检查了2016年至2020年期间在台湾水域(包括岛屿)收集或存放在博物馆的标本。通过细胞色素氧化酶I亚基DNA条形码标记和形态鉴定，共鉴定出71种。最小种间距离均大于4.09%，除了两个未确定类群:Charybdis miles (De Haan, 1835)和Ch. sagamiensis Parisi(1916)，以及Thranita pelsarti (Montgomery, 1931)和Thr。prymna (Herbst, 1803)。此外，台湾新记录有Carupa ohashii Takeda(1993)、Lupocyclus inaequalis (Walker, 1887)、Luu.等9属14种。tugelae Barnard, 1950, Lupocycloporus minutus (Shen, 1937)， Monomia gladiator (Fabricius, 1798)， M. lucida Koch & Ďuriš， 2018, Podophthalmus minabensis Sakai, 1961, Thalamita gatavakensis Nobili, 1906, Tha。A.米纳-爱德华兹，1869,Tho。三叉戟A. Milne-Edwards, 1869, Thr。cerasma (Wee & Ng, 1995);(Hombron & Jacquinot, 1846)和Xiphonectes tuberlosus (A. Milne-Edwards, 1861)。本研究结果使台湾梭鲈科总种数增至89种。

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.
