Abstract
In this study, we have performed morphological and molecular analyses of a phylogenetic group (VIG2) in the complex of Baikal cyclopoids that are morphologically similar to Diacyclops versutus, D. improcerus and D. galbinus. The first internal transcribed spacer (ITS1) and the mitochondrial cytochrome c oxidase subunit I (COI) were chosen as molecular markers. We have measured 27 morphological features and obtained values of 18 morphometric characteristics. We present an illustrated description of the females VIG2. We show that representatives of VIG2 belong to the new taxonomic group Diacyclops in Lake Baikal. Genetic and morphometric differences in the representatives of VIG2 from four locations are comparable to the intraspecific level of differences.
