Abstract

The variability of morphological characters and coloration features used for identification of the species Cobitis saniae has been studied using the materials from the collection of the Zoological Museum of Lomonosov Moscow State University, which includes voucher samples with genetically confirmed species status, in order to clarify the dynamics of the diversity of spined loaches in Transcaucasia in the anthropogenic period. Significant variability of many characteristics at the intraspecific level has been revealed. Previously proposed taxonomic keys do not allow to identify correctly C. saniae and C. faridpaki, which are accepted in the status of cryptic allopatric species differentiated by the analysis of the mitochondrial genome. The characters are suggested that make it possible to differentiate C. saniae from C. taenia and C. melanoleuca, inhabiting the basin of the Caspian Sea, and from two species known from water bodies within the modern range of C. saniae: Khvalynskaya spined loach C. amphilekta, common in the basin of the Kyzylagach Bay in the 1930s, and a new species C. derzhavini described from the Kura River basin.

根据博物馆收藏的数据，在人为时期内，居住在高加索地区的科布斯氏梭状棘突棘的多样性动态。I.哥白炎（Cobitidae）的形态变异和诊断特征

摘要

莫斯科罗蒙诺索夫动物学博物馆收藏的材料中研究了用于鉴定Sania Cobitis saniae物种的形态特征和着色特征的变异性，其中包括具有遗传学确认物种状态的凭证样本，以阐明人为时期高加索地区旋转泥lo的多样性动态。已经揭示出种内水平上许多特征的显着变异性。以前提出的分类密钥不允许正确识别C. saniae和C. faridpaki，这是通过线粒体基因组分析区分的隐性异源物种的状态。该字符建议，使它们能够区分C. saniae从C.绦虫和C.大熊猫，栖息在里海盆地，并从两个物种的现代范围内水体称为C. saniae：Khvalynskaya花鳅C. amphilekta，常见于1930年代的Kyzylagach湾盆地，以及一种从库拉河流域描述的新物种C. derzhavini。
