“…Bramina (6 nipples) are unique for retaining both pectoral pairs but losing an inguinal pair; an identical situation is known in the Nearctic Microtus guatemalensis and M. ochrogaster (Niethammer 1972). Liu et al (2018) report 1 pectoral and 1 inguinal pair for Eothenomys (4 nipples) which contradicts Hinton (1923:147); this is typical of the Nearctic Microtus mexicanus. Further combinations of nipples were observed in Nearctic voles, along with up to 10 nipples in Ondatra (Niethammer 1972).…”

“…The baculum is well ossified and of characteristic arvicoline structure, i.e. consisting of a larger proximal baculum with an expanded base and 3 distal bones, of which the medial is the most prominent (for details see Yang et al 1992, andLiu et al 2018). Skull is heavy, deep and wide with distinctly bowed zygomata (ZgW/CbL=0.53-0.63).…”

“…The glans penis (length=3.6-4.4 mm, width=2.4-2.5 mm) is cylindrical and wide; its apex is truncate and the urethral lappet in the pennial crater has 3 terminal forks (Yang et al 1992). Dimensions (x̄±SD; mm) of proximal baculum in adult voles: length=2.12±0.21; length of medial and lateral distal bones=1.07±0.14 and 0.80±0.15, respectively (Liu et al 2018). The skull is rather deep and zygomatic arches are distinctly bowed (ZgW/CbL=0.56-0.62).…”

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.

The climbing mouse is a rare, small mammal listed as an endangered species on the China species red list. Molecular phylogenetic analyses and the evolutionary history of the genus remain unexplored because of the extreme difficulty in capturing individuals and their narrow distribution. Here, we collected 44 specimens, sequenced one mitochondrial and eight nuclear genes, and integrated morphological approaches to estimate phylogenetic relationships, delimit species boundaries, and explore evolutionary history. Molecular analyses and morphological results supported the validity of these four species. Here, we describe two new species, Vernaya meiguites sp. nov. and Vernaya nushanensis sp. nov., and recognize Vernaya foramena, previously considered a subspecies of Vernaya fulva, as a valid species. The estimated divergence time suggests that the climbing mouse began to diversify during the Pliocene (3.36 Ma).

Spatial patterns and determinants of species richness in complex geographical regions are important subjects of current biogeography and biodiversity conservation research. Glires are small herbivorous mammal species with limited migratory ability that may serve as an indicator of biodiversity and ecosystems. Herein, we aimed to evaluate how multiple ecological hypotheses could explain the species richness patterns of glires in China. Initially, we constructed a mapping grid cell operating units of 80 × 80 km 2 which covered China's land mass and mapped the distribution ranges of the 237 glires species that had recorded. The glires taxa were separated into three response variables based on their distribution: (a) all species, (b) nonendemic species, and (c) endemic species. The species richness patterns of the response variables were evaluated using four predictor sets: (a) hydrothermal characteristics, (b) climatic seasonality, (c) habitat heterogeneity, and (d) human factors. We performed regression tree analysis, multiple linear regression analysis, and variation partitioning analyses to determine the effects of predictors on spatial species patterns. The results showed that the distribution pattern of species richness was the highest in the Hengduan Mountains and surrounding areas in southwest China. However, only a few endemic species adapted to high‐latitude environments. It was found that there are differences about the determinants between nonendemic and endemic species. Habitat heterogeneity was the most influential determinant for the distribution patterns of nonendemic species richness. Climatic seasonality was the best predictor to determine the richness distribution pattern of endemic species, whereas this was least affected by human factors. Furthermore, it should be noted that hydrothermal characteristics were not strong predictors of richness patterns for all or nonendemic species, which may be due to the fact that there are also more species in some areas with less precipitation or energy. Therefore, glires are likely to persist in areas with characteristics of high habitat heterogeneity and stable climate.
