Abstract

Abstract The genus Centroptilum Eaton, 1869 is widely distributed in the West Palaearctic region, but poorly diversified as it previously only encompassed two valid species, C. luteolum (Müller, 1776) and C. pirinense Ikonomov, 1962. The discovery of a new congener, C. volodymyri Martynov, Godunko and Palatov, sp. nov., is therefore remarkable; the new species is described based on larvae collected in Georgia, Turkey and Iran in 2012–2019. This new species can be distinguished by the structure of the cuticle with flattened, stretched shallow, triangular and semilunar-shaped corrugations; scales and their bases densely scattered on body surface; features of the mouth parts, including the presence of an expanded laterally labrum, in combination with segment III of maxillary palp and superlinguae of hypopharynx rounded apically, without any pointed projections at the tip; numerous small teeth scattered proximally in two rows along inner margin of the pretarsal claw; the shape of denticulation along the posterior margin of the abdominal terga, and the number of prominent posterolateral spines on tergum VII; and the shape of gills II–VII, with a distinctly concave posterior margin. Together with a morphological description, data on the distribution and mitochondrial cytochrome c oxidase subunit I gene (COI) barcode sequences of the species are provided. The species delimitation of C. volodymyri Martynov, Godunko and Palatov, sp. nov. and C. luteolum is tested using COI barcode sequences. The data obtained show that the new species can be distinctly recognised as a separate lineage. The habitat preferences associated with the different parts of the area of C. volodymyri Martynov, Godunko and Palatov, sp. nov. are described and compared. Distribution of C. volodymyri Martynov, Godunko and Palatov, sp. nov. confirms the connections between Caucasian and Asian fauna of Ephemeroptera, as already demonstrated in various families and genera. Short notes on the distribution of mayfly species common to the Caucasus, north-western Iran and Central Asia are presented. http://www.zoobank.org/urn:lsid:zoobank.org:act:1D2B7557-0DEC-4ACD-8CA3-A6B50FCC4A51.

1869年在格鲁吉亚、土耳其和伊朗发现的一种新物种(蜉蝣目:巴伊蝶科)

摘要:Centroptilum Eaton, 1869属广泛分布于西古北地区，但其多样性较差，因为之前只有C. luteolum (m ller, 1776)和C. pirinense Ikonomov, 1962这两个有效种。一个新的同族的发现，C. volodymyri Martynov, Godunko和Palatov, sp. nov.，因此是显著的;新物种是根据2012-2019年在格鲁吉亚、土耳其和伊朗收集的幼虫描述的。该新种的角质层结构为扁平的、伸展的浅的、三角形的和半月形的波纹;鳞片及其基部密散于体表;口部特征，包括有扩张的外侧唇，与上颌腭第三节和下咽上舌结合，顶部圆形，尖端无任何尖突;沿前爪的内缘近端散布的许多小齿在二排;腹第七节后缘齿状突起的形状和第七节突出的后外侧棘的数目;和鳃的形状II-VII，具有明显凹的后缘。结合形态学描述，提供了该物种的分布和线粒体细胞色素c氧化酶亚基I基因(COI)条形码序列的数据。利用COI条形码序列对C. volodymyri Martynov, Godunko and Palatov, sp. 11和C. luteolum进行了物种划分。获得的数据表明，新物种可以被清楚地识别为一个单独的谱系。本文描述并比较了C. volodymyri Martynov, Godunko和Palatov, sp. 11 .在不同地区的生境偏好。C. volodymyri Martynov, Godunko和Palatov, sp. 11 .的分布证实了蜉蝣目在高加索和亚洲动物群之间的联系，正如已经在不同科和属中证明的那样。简要介绍了高加索、伊朗西北部和中亚常见的蜉蝣种类的分布。http://www.zoobank.org/urn: lsid zoobank.org d2b7557-0dec-4acd-8ca3-a6b50fcc4a51行为:1。

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.
