Abstract

ABSTRACT Molecular data were used to revise the diversity of the genus Cryptomonas in Russia, using samples collected across nine geographic regions within Russia from 2015–2019. Several molecular markers were used: nuclear SSU, LSU and ITS2 rDNA, and plastid psbA. In total, 24 species of the genus Cryptomonas were identified in the country’s fresh waters based on 122 different strains. Six new species were identified and are described here (Cryptomonas matvienkoae sp. nov., C. furtiva sp. nov., C. paludosa sp. nov., C. ursina sp. nov., C. kisselevii sp. nov. and C. meshchorana sp. nov.), and three taxa are emended (Cryptomonas skujae, C. platyuris and C. obovata). These new and emended species group in clades with the previously described species or represent new lineages on the phylogenetic tree. Seven morphospecies, previously reported in Russia, are confirmed by molecular methods, and two unidentified taxa are also reported. HIGHLIGHTS Molecular investigations of the genus Cryptomonas in Russia revealed 24 species. Descriptions of three species were emended. Six species new to science were described.

俄罗斯隐单胞菌属（隐藻科）的分子多样性

摘要分子数据用于修正俄罗斯隐单胞菌属的多样性，使用了2015-2019年在俄罗斯九个地理区域收集的样本。使用了几种分子标记：核SSU、LSU和ITS2 rDNA，以及质体psbA。根据122种不同的菌株，在该国淡水中总共鉴定出24种隐单胞菌属。鉴定并描述了6个新种（隐单胞菌matvienkoae sp.nov.，C.furtiva sp.nov..，C.paludosa sp.nov.C.ursina sp.nov.%，C.kisselevii sp.nov'.和C.meshchorana sp.novy.），并校正了3个分类群（隐单孢菌skujae，C.platouris和C.obovata）。这些新的和修正的物种与先前描述的物种在分支中分组，或者在系统发育树上代表新的谱系。先前在俄罗斯报道的七个形态物种通过分子方法得到了证实，另外还报道了两个未鉴定的分类群。亮点俄罗斯隐单胞菌属的分子调查揭示了24种。对三个物种的描述进行了修订。描述了六个科学上新发现的物种。
