The X chromosome is a medium-sized submetacentric. This karyotype corresponds to the Evoron vole of the Argi race (Kartavtseva et al. 2021 a). Chromosome numbers are assigned according to the previously published data for voles with 36 chromosomes: karyotype 2 n = 36 b. Without differential staining of chromosomes, we cannot confidently state which chromosomes underwent structural rearrangements and the type of these rearrangements. Body measurements of the Evoron vole from four populations (Table 2 and Fig. 2) show two groupings. The first group includes populations I and III, the second populations II and IV. Population IV studied by us for the first time is similar to population II. The Tyrma and Urgal rivers (population II) originate in the southwestern slopes of the Bureinsky Range and flow into the Bureya River (Fig. 1: A). In the lower reaches, the Tyrma River makes a sharp bend, inside which swampy lowlands overgrown with grass and tussock meadows with small areas of broad-leaved forests predominate (Fig. 1: B). Both populations (II and IV) are located in the western spurs of the Bureinsky Range. These populations may have a common origin. However, drawing the conclusion about the similarity of populations with those studied previously requires further morphological and genetic investigation. Karyotyping of one female (2 n = 36) revealed a similarity with the Argi chromosomal race of the A. evoronensis (karyotype 36 = 36 b) from populations II and III. The new records of voles in the Tyrma River valley expand the range of Evoron vole and indicates more southerly habitats than previously stated.	en	Kartavtseva, Irina V., Stepanova, Anastasia I., Sheremetyeva, Irina N., Pavlenko, Marina V., Frisman, Liubov V.
