“…Enamel pattern is complex (Figure 220c-e'): M1 with 5 (rarely 4) inner and 3-4 outer reentrant angles; T5 is either isolated or confluent to the AC; BR4 is usually obtuse and LR5 is normally deep. M 3 has 4 inner and 3-4 outer re-entrant angles; BR4 is feeble (Dokuchaev 2014); triangles T5-T6 are typically confluent (Bannikova et al 2010). Karyotype: 2n=44, NF=60; there are 16 pairs of bi-armed and 28 pairs of acrocentric chromosomes; both sex chromosomes are acrocentric (Vorontsov et al 1988, Kartavtseva et al 2008, Sheremetyva et al 2009).…”

As the most species-rich group of Palaearctic rodents, voles and lemmings are frequently used in various research endeavours of fundamental and applied significance. The present work integrates achievements of the genomic era with the traditional taxonomy and provides an authoritative and up-to-date taxonomic guide to the animal group which is of great interest to experts engaged in medical zoology, epidemiology, biostratigraphy, zooarchaeology, evolutionary research, population ecology, animal systematics, biodiversity conservation, museum collection management and many more biological subdisciplines. The text is supplemented by 331 illustrations and over one thousand references. Depicted are morphological details of skull and dentition of each of the 128 species and their distributions are mapped in detail. The book will allow the user to interpret intelligently and cautiously the interrelationships among species of voles and lemmings and to follow the anticipated taxonomic change with a critical eye.

“…Огнев описал подвид «Microtus oeconomus shantaricus» (Огнев [Ognev] 1914), а в наше время Н.Е. Докучаев доказал приоритет названия Alexandromys shantaricus над Alexandromys gromovi (Dokuchaev 2014;Dokuchaev and Sheremetyeva 2017). Ранее считалось, что в области восточносибирской части ареала A. oeconomus любые зубы с подобным слиянием принадлежат только этому виду, поскольку о виде «Microtus gromovi» Vorontsov et al, 1988 ничего не было известно (ни о наличии «экономусного слияния», ни о его распространении, кроме типового место обитания), а «Microtus limnophilus» Büchner, 1889 с таким же слиянием m1 (Приложение 4: Рис.…”

Far-Eastern grey voles Alexandromys (Rodentia: Cricetidae) from Medvezhyi Klyk cave Late Pleistocene–Holocene deposits, Primorskii Kray, Russia

The current paper describes material from Medvezhyi Klyk Cave Late Pleistocene–Holocene deposits that represented mostly by isolated teeth. The morphology and size variation of the first lower teeth (n = 542) were studied. There are Alexandromysfortis, A. cf. maximowiczii, A. cf. oeconomus, A. cf. mongolicus determined in the material. We could not determine the taxa due to uncertainty in a spatial variation of the species ranges during Late Pleistocene and Holocene, a broad variety of the m1 anteroconid shape among medium-sized species of voles, and supposed presence “archaic” and “deviant” morphotypes of m1. Geometric morphometrics methods were shown the broad variety of the m1 anteroconid shape without strict species-relation, i.e., each tooth shows proper anteroconid shape, which can repeat within limits in populations in and among species.
