From the perspectives of biodiversity conservation and management, there is an urgent need to have at hand current synopses of classification and distributions of species. In this paper, we review and summarize the classifications, Chinese and English names, type specimens, type localities and distributions of China’s lizard fauna to promote scientific exchange and species conservation among relevant people in China and internationally. As of December 31, 2020, a total of 230 species of lizard, belonging to 44 genera and 12 families, have been recorded from China, including 4 invasive species: 2 in the family Gekkonidae, 1 in Iguanidae and one in Dactyloidae. There are 115 endemic species, accounting for 50% of this group. The proportion of endemic species to China was the highest in the family Eublepharidae (84.62%), and the number of endemic species to China was the highest in the family Agamidae (42 species). The species distributions and classification in the “Fauna Sinica (Reptilia 2): Squamata (Lacertilia)” were updated. Among the provincial administrative units, there is a larger number of species in the southern provinces, such as Yunnan, Guangdong, Guangxi and Taiwan. Sichuan, Yunnan, and Taiwan harbour relatively more endemic species than others. A total of 154 species of lizards were first discovered in China, and the type localities of these species are concentrated in Yunnan, Taiwan, Tibet, Xinjiang, and Sichuan.

New finds of the lizards of Eremias multiocellata complex became known for extreme southeast of Kazakhstan. In 2006-2007 re recorded the lizards in the mountain valleys of Kegen and Tekes Rivers creossing an intermountain depression located between Ketmen’ and Terskey-Alatau at altitude 1850-1950 m a.s.l. Morphological analysis revealed the reliable differences of the specimens collected from other species of multiocellata complex inhabited the close areas – E. stummeri from Issyk-Kul’ Depression and E. kokshaaliensis from Sary-Dzhaz River Basin of Kyrgyzstan. Morphological peculiarity of the populations recorded may be caused by their isolative position in extreme southeast of Kazakhstan and needs future elucidation.

The distribution and habitat characteristics of two Eremias species (E. arguta and E. stummeri) from contiguous areas of southeastern Kazakhstan, northeastern Kyrgyzstan, and western Xinjiang, China, were analyzed using GIS modeling. We show that both species are dry-steppe-adapted xerophilous lizards with sclerophilic and partially petrophilic specialization. In spite of the visible similarity of the ecological niches (ENs) occupied by E. arguta and E. stummeri, the latter differs in a number of key variables. While most of the precipitation variables, the radiation of the winter and off-season months, and afternoon (PM) humidity are most important for E. arguta habitats, the habitats suitable for E. stummeri are limited by temperature variables, radiation during most of the year, and morning (AM) humidity. Differences on this scale indicate the way in which these lizards are adapted to different ecosystems — E. arguta to the plains and E. stummeri to the mountains — and support the views on their different zoogeographical accessory. Avisible correspondence of the distributional pattern of the two Eremias species to the mountain piedmonts and low foothills, with Pliocene-Quaternary concreted pebble deposits and the loess strata, permit us to consider mountain trails as the most likely means by which the species expanded in the Late Cenozoic period. Pronounced isolation of the populations in the Northern and the Central Tien Shan intramontane depressions appears as a factor from at least the Late Pliocene (E. stummeri) and the Middle Pleistocene (E. arguta) periods; and the association of the lizard habitats with loess deposits has given rise to the suggestion that there was an absence of serious change in their ranges during the Last Glacial Maximum (LGM). Low precipitation, a high annual temperature range and the high aridity of the climate in general beyond the ENM optimum of E. arguta all point to severe conditions for lizards surviving already in the eastern part of the Ily Basin and explain the limited species distribution in the highly arid deserts of Xinjiang. In terms of methodology, our data highlights the lack of a ‘generalized set’ of BIOCLIM parameters in the ecological niche modeling of the mountain species. In particular, moisture and solar radiation as well as the relief variables play an important role in the ecological health of the poikilothermic xerophilous species inhabiting mountain areas.

The status of Eremias stummeri in China has been a matter of controversy for over two decades, although it is well acknowledged that this species occurs in Northeast Kyrgyzstan and Southeast Kazakhstan. To date, whether its occurrence extends to the adjacent Chinese region (possibly in the Ily River Valley) has not been confirmed yet. To overcome constraints on field surveys imposed by the region’s remoteness and rugged terrain, we targeted areas of further field inventories by estimating the potential distribution of the species. Ecological niche modeling (ENM) enabled us to predict a continuous distribution area from Kazakhstan to the Chinese part of the Ily River Valley in Zhaosu county for the species’ occurrence. We conducted extensive field surveys in the predicted area. In 2017, for the first time, the occurrence of E. stummeri in China was confirmed with a single find in Zhaosu county. Further morphological and multilocus phylogenetic analyses congruently supported the taxonomic status of the recently discovered population as E. stummeri. In contrast to its distribution continuity between Kazakhstan and China, the ENM indicates distribution discontinuity between Kazakhstan and Kyrgyzstan. This geographic distribution pattern of E. stummeri is supported by morphological and molecular evidence, which highlights that individuals from China and Kazakhstan are more closely related to each other than to those from Kyrgyzstan. The mismatch between mitochondrial and nuclear phylogeographic pattern implies that historical mitochondrial introgression occurred from E. stummeri individuals from Kyrgyzstan to those from Kazakhstan.

Four species from the E. multiocellata-complex occur in Kyrgyzstan and southeastern Kazakhstan. e taxonomic state of the populations from Kazakhstan is ambiguous. e results of comparative morpho- logical analysis (habitus, color pattern on the dorsal side of the body, metric and meristic characters) in the E.stummeri from two localities in Kyrgyzstan (including type locality) and south-eastern Kazakh- stan are presented. Signi cant di erences were revealed in Sq., G. and L. /L. cd features. As a result, the racerunners from the southeastern Kazakhstan are morphologically identi ed as E. stummeri. Our ob- servations and the analysis of the museum collections con rm independent speci c states of three allo- patric species of E. multiocellata-complex in Kyrgyzstan and Kazakh Tien Shan.

We provide an integrative analysis of the diversity of the E. multiocellata—E. przewalskii species complex in Central and Middle Asia using morphological and molecular (COI DNA-barcoding) data. We report preliminary data on mtDNA variation within this group and clarify the taxonomic status and distribution of the members of the species complex. We also provide a description of a new Eremias species from Eastern Kazakhstan and western Mongolia, where it occurs in sympatry with E. multiocellata sensu stricto, from which it can be clearly differentiated using both morphological and molecular characters. The new species, described as Eremias dzungarica sp. nov., is assigned to the subgenus Pareremias on the basis of the following features: subocular not reaching mouth edge; one frontonasal; two supraoculars; the row of small granular scales between supraoculars and frontal with frontoparietals absent; distance between the femoral pore rows being wide; femoral pore rows not reaching knee-joint; coloration pattern with light colored ocelli with black edging. The new species can be distinguished from its congeners on the basis of the following morphological attributes: a mediumsized lacertid lizard, maximum snout-vent length (SVL) = 64.5 mm, tail being ca. 1.5 times longer than body length (SVL), hindlimbs relatively long (hindlimb length to SVL ratio 0.46); subocular scale not reaching mouth edge, in touch with 6–8 supralabials; males with bright coloration consisting of 2–3 dorsolateral rows of light-colored ocelli with thick black edging; the ventral row of ocelli in life is greenish to bluish; dorsal pattern consisting of black irregular blotches along the middorsal line. We also report on the high genetic and morphological diversity of E. multiocellata in Mongolia and China, synonymize E. m. bannikowi with the nominative form E. m. multiocellata, discuss variation within E. przewalskii, synonymize E. p. tuvensis with the nominative form E. przewalskii, provide new data on E. cf. reticulata and E. m. tsaganbogdensis, confirm validity and clarify distribution ranges of E. stummeri, E. szczerbaki and E. yarkandensis and discuss further progress on taxonomic studies of the E. multiocellata—E. przewalskii species complex.

The Kokshaal racerunner, Eremias kokshaaliensis Eremchenko et Panfilov, 1999, together with other central Asian racerunner species, is included in the Eremias multiocellata complex. In the present work, for the first time, the results of the analysis of historical mitochondrial DNA (barcode) are presented and the taxonomic status and preliminary phylogenetic relationships within the complex are specified. We present, for the first time, the results of the molecular analysis using historical DNA recovered from specimens of several species of this complex (paratypes of the Kokshaal racerunner and historical collections of the Kashgar racerunner E. buechneri from Kashgaria) using DNA barcoding.

This book shows a comprehensive picture of the reptiles, excluding snakes, living in Europe, North Africa, Middle and Near East and Central Asia. The bulk of the book is an annotated checklist and a distributional atlas of approx 500 species of lizards, crocodiles, turtles and terrapins, and amphisbaenians, living in the Western Palearctic. Information on distribution, subspecies, chorotype and main references are provided for each species, as well as 226 colour maps showing the global distribution of the species on a grid of one degree. For each species map the bibliographic and original sources (more than 850 sources are listed) are indicated. A further 83 maps show the distribution of all genera and main species groups of Palearctic reptiles. Beside the checklist and the atlas, in some additional chapters the following arguments are treated: Materials and methods; status of knowledge on the Palearctic fauna; composition of the Western Palearctic reptile fauna (including a statement on biodiversity and species richness); descriptive biogeography (including a discussion on the Palearctic region boundaries based on reptile distribution and the herpeto-geographic sectors of the Western Palearctic); conservation status. A list of more than 730 references quoted in the text and high quality colour plates including photos of the most of the supraspecific taxa living in the study area completes the book.

By the PAAG electrophoretic spectra of Coomassi-stained 61-73 bands from 4 “tissues” (heart, skeletal muscle, kidney, liver proteins) for each of 17 specimens representing at least 3 or 4 species, (Eremias vermiculata Blanf., E. przewalskii Str., E. sp. and E. multiocellata Gunther) were compared.Most of the specimens were collected in Mongolia. Their tree, based on several measures of genetic distances, showed the order of the species listed above, with E. sp., the closest to the point of divergency, and situated between E. przewalskii and the specimen of E. multiocellata from several localities and biotypes. The genetic similarity of the biotypes of the last species is discussed in regard with other data on the body size and proportion, pholidosis, coloration.

The whole mitochondrial genome was determined from a viviparous racerunner, Eremias stummeri, which was collected from southeast Kazakhstan. The mitogenome sequence was 19 602 bp in size, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a control region, which is similar to the typical mtDNA of vertebrates. Mitochondrial genomes analyses using maximum parsimony and Bayesian analyses yielded identical phylogenetic trees, indicating a close phylogenetic affinity of the sampled taxa in genus Eremias. Monophyly of both Eremias and its viviparous group is recovered. The complete mitogenome sequence of E. stummeri provides fundamental data for resolving phylogeneitc and genetic problems related to Eremias viviparity.
