In an intermontane kettle at the southwestern spurs of the Bureinsky Mountain Range, in the Bureya River basin, the Ussuri white-toothed shrew has been recorded for the first time. This locality lies north of the previously supposed species distribution range in the south of the Russian Far East. The study of the female karyotype has allowed us to describe the morphology of the chromosomes of Crocidura lasiura (2n = 40, NF = 54). The karyotype differs from the earlier published information (2n = 40, NF = 56) on the number of subtelocentric autosomes. The data obtained expand the northern range limit of the Ussuri white-toothed shrew and show variability in the number of chromosome arms (NFа = 50, 52).
