Abstract

The DNA-barcoding and chromosomal study of the eastern water bat, Myotis petax Hollister, 1912, from the earlier unexplored localities in the Russian Far East are carried out. The COI barcoding obtained for 18 from a total of 19 individuals captured in five localities in the Russian Far East showed the low nucleotide variability with the prevalence of the central, the most abundant haplotype. The chromosomal characteristics of eight M. petax specimens (2n = 44, NFa = 52) in the Russian Far East are clarified. The number and localization of NOR in karyotype of M. petax is described at the first time and differ from distributional patterns of NOR in the sibling species M. daubentonii Kuhl, 1819 that can be used as diagnostic feature. The considerable intraspecific variability in the distribution of heterochromatin material revealed is not typical of the genus Myotis, but it has been found in other species of the family Vespertilionidae.

俄罗斯远东地区peotis(翼翅目，狐蛉科)的dna条形码及核型新资料。

对俄罗斯远东地区早期未开发地区的东部水蝙蝠Myotis petax Hollister, 1912进行了dna条形码和染色体研究。从俄罗斯远东地区5个地点捕获的19个个体中获得的18个COI条形码显示，核苷酸变异性低，中心单倍型最丰富。澄清了俄罗斯远东地区8个M. petax标本(2n = 44, NFa = 52)的染色体特征。该研究首次描述了M. petax核型中NOR的数量和定位，与兄弟种M. daubentonii Kuhl, 1819中NOR的分布模式不同，可作为诊断特征。在异染色质物质分布上的相当大的种内变异性在Myotis属中并不典型，但在vespertilonidae科的其他物种中也发现了这种变异性。
