A new species, Baetis majus Tiunova sp. nov., is described and illustrated based on larvae and reared adults discovered in the Russian Far East. The differential identification of this species was determined by the characteristics of other representatives of the genus Baetis Leach, including subgenera Baetis Leach and Tenuibaetis Kang Yang from Eastern and Western Palaearctic, Nearctic and Oriental regions. In addition to morphological studies, DNA barcoding of the described species with average intraspecific K2P distances to nearest neighbours is documented. We reconstructed the phylogenetic relationships of all available cytochrome c oxidase subunit I (COI) sequences of the subgenera of Baetis and Tenuibaetis from four regions. Bayesian analysis using 47 morphological characters additional to partial COI sequences did not allow to determine the species-group of the Baetis genus to which the described species belongs.
一种新的物种，即大型蜉 Baetis majus Tiunova sp. nov.，是根据在俄罗斯远东地区发现的幼虫和饲养成虫描述和说明的。通过与其他蜉属代表的特征进行比较，确定了该物种的差异识别，包括来自东、西古北界、新北界和东洋界的蜉属的亚属 Baetis Leach 和 Tenuibaetis Kang Yang。除了形态学研究，还记录了描述物种的 DNA 条形码，与最近邻的平均种内 K2P 距离。我们重建了来自四个地区的蜉属和 Tenuibaetis 亚属的所有可用细胞色素 c 氧化酶亚基 I (COI) 序列的系统发育关系。使用 47 个形态特征和部分 COI 序列的贝叶斯分析，无法确定描述物种所属的蜉属的物种群。
