The Cadastre of the Genetical Fund is the of cial directory on biodiversity – the annotated check-list of living creatures registered on the territory of the country, re ecting the current state of the biotic inventory. The present volume IV is devoted to the chordates and contains general distributional data about representatives of ve classes of vertebrate animals: ray- nned shes (Actinopterygii), amphibians (Amphibia), reptiles (Reptilia), birds (Aves), and mammals (Mammalia). This volume completes the national faunal inventory (the check-list of all invertebrate animals is presented in volumes II and III). In total, there are listed 602 species (with all local subspecies) represents 325 genera belongs to 119 families. There are also included 14 species doubtfully recorded in Kyrgyzstan, and 36 species names are expunged from faunal list. Each taxon name is supplied with the main synonymy, most accepted Russian, Kyrgyz, and English names. Data on current distribution within Kyrgyzstan and endemicity level are provided for each species (subspecies), as well as main references. The guide book also contains 74 color photographs in the annex. It is destined for experts in ecology, zoologists, specialists and employers of the institutions for the management of the natural resources, nature conservation and biological education.

Takhar Province of Afghanistan was previously known to harbour only two species of amphibians and eight species of reptiles with no record of snake species. From 2020 to 2021, we collected herpetological data from the Province and identified 14 species and specimens representing species complexes (Bufotes viridis complex and Trapelus agilis complex), with first records of Testudo hors fieldii (Testudinidae), Paralaudakia badakhshana (Agamidae), Pseudopus apodus (Anguidae), Tenuidactylus caspius (Gekkonidae), Eumeces schneideri (Scincidae) and Varanus griseus (Varanidae). In addition, we report the first province records of snakes, includ ing Eryx tataricus (Erycidae), Hemorrhois ravergieri (Colubridae), Natrix tessellata (Natricidae) and the venomous species Naja oxiana (Elapidae). These records connect and supplement previously obtained data of these species from surrounding provinces and neighbouring countries. Our data reveal that Takhar Province is home to at least 20 species of amphibians and reptiles with a strong affiliation to the Turanian chorotype. All these data are a significant source of information for the diversity of herpetofauna in Afghanistan and subsequent biodiversity research in the Central Asiatic region.

The rapid racerunner, Eremias velox, is a widely distributed lizard from the northern Caucasus across entire Central Asia eastward to China. It is increasingly common to accept E. velox as a species complex in its entire range. To date, published morphological and molecular systematic hypotheses of this complex are only partially congruent, and its taxonomic status and evolutionary history are still far from clear. The mitochondrial cytochrome b gene and 12S rRNA sequences were used to evaluate the taxonomy of this complex, with particular attention to the phylogenetic placement of populations in northwestern China. Examination of the phylogenetic analyses recovers seven distinct, biogeographically discrete, and well-supported clades, revealing genetically identifiable populations corresponding to some previously morphology-defined subspecies. Chinese E. v. roborowskii appears to have split from other Central Asian rapid racerunner lizards well before differentiation occurred among the latter taxa. Specifically, we corroborate that there are two subspecies occurring in China, i.e., E. v. velox and £. v. roborowskii. We recommend a novel subspecific status for the phenotypically and genetically distinct populations in southern Aral Sea region of Uzbekistan previously assigned to E. v. velox. Finally, each of the three independently evolving lineages from Iranian Plateau should be recognized as three species new to science under the general lineage concept.

The background species of the saurofauna of the southeastern periphery of the Tersk Sands in the early 1980s were Phrynocephalus guttatus (Gmelin, 1789), Eremias velox (Pallas, 1771) and Eremias arguta (Pallas, 1773). Research conducted in 1983–1984 showed that each of them had different preferred biotopes: Phr. guttatus – blown sands, E. arguta – fixed sands, E. velox – scattered shrubbery. At the turn of the 20th and 21st centuries, Phr. guttatus completely disappeared in the study area on the southeastern periphery of the Tersk Sands, and after 2008 - E. velox. Currently, the territory is inhabited by E. arguta and the widespread Lacerta strigata Eichwald, 1831. The rapid changes in the composition of the saurofauna can be explained primarily by the strict biotopic confinement of lizards in conditions of total steppification of the Terek sands. The transformation of landscapes brought stenobiont species, in the conditions of the Eastern Pre-Caucasus psammophile species of Turanian genesis, to the brink of extinction and created favorable conditions for eurybiont and/ or steppe forms. If existing trends continue, we can expect the complete disappearance of such obligate psammophiles as Phr. mystaceus (Pallas, 1776) and Phr. guttatus in the Terek Sands. They may be followed by Trapelus sanguinolentus (Pallas, 1814) and E. velox. In this case, biotopic preferences of a species determine their current and prospective sociological status.

Der Nordosten Irans, ein faszinierendes Gebiet, einerseits durch die immense Ausdehnung arider (Hoch-) Ebenen und Hügelländer, andererseits durch die überraschende landschaftliche Vielfalt unmittelbar südlich des Kaspischen Meeres. So kontrastieren die beeindruckend dichten Hyrcanischen Wälder und das über 5000 m hohe Elburs-Gebirge die endlosen, staubtrockenen Weiten im Landesinneren. Dementsprechend groß ist auch die dortige Artenvielfalt: Knapp 60 Reptilien- und Amphibienarten konnten im Zuge der 14-tägigen Exkursion auf der 4000 km langen Rundtour beobachtet werden.

We present an annotated checklist for a total 241 reptiles and 22 amphibians including 5 frogs, 9 toads, 7 newts and salamanders, 1 crocodile, 1 worm lizard, 148 lizards, 79 snakes and 12 turtles and tortoises, includes the most scientific literature up to August 2014 and also based on several field surveys conducted in different Provinces of Iran from 2009 to 2014. We present an up-to-dated checklist of reptiles and amphibians in Iran. We provide a comprehensive listing of taxonomy, names, distribution and conservation status of all amphibians and reptiles of Iran. This checklist includes all recognized named taxa, English names for classes, orders, families, species, subspecies along with Persian names for species, including indication of native and introduced species. For the first time we report two non-native introduced reptiles from natural habitats of Iran. Of the total 22 species of amphibians in Iran, 6 (27.2%) are endemic and of the total 241 species of reptiles, 55 (22.8%) are endemic. Of the 22 amphibians species in Iran, 3 (13%) are Critically Endangered, 2 (9%) are Vulnerable and of the 241 reptile species 3 (1.2%) are Critically Endangered, 4 (1.6%) are Endangered and 10 (4.1%) are Vulnerable. Accordingly, this paper combines significant aspects of taxonomy, common names, conservation status and distribution of the Iranian herpetofauna.

The work provides new information on the distribution and abundance of reptiles in some landscapes of Turkmenistan. The results of the study are following: the registration of new records to clarify the distribution; the discovery of the Afghan awl-headed snake (Lythorhynchus ridgewyi) on the Kaplankyr chink, which moves the boundary of the species distribution from the previously known nearest places (in the vicinity of the village of Kukurtli (former Sulfur Plant) and from the solonchak hollows of Unguz (Shestopal, Akgaev, 2013) to 220 km to the north-west; sunwatcher living in the north of Turkmenistan is identified as nominate subspecies — Phrynocephalus helioscopus helioscopus. Data on the number of reptiles are provided, the most interesting of them are observations in the southern part of the Sarykamysh depression. The density of desert species such as Trapelus sanguinolentus aralensis) and (Eremias intermedia) is twice higher and for Eremias lineolata is 20-times higher in comparison with adjoining territories.

We present a comprehensive summary of the distribution of the lizards of Iran accompanied by an annotated checklist. The updated maps of distribution of all 146 species of 41 genera of 11 families are based on all available bibliographic records, catalogues of museum collections and our own field observations. The final dataset used for the distribution maps contains 8525 georeferenced records and cover 41% of the country when plotted on a grid of 0.25° × 0.25° resolution. The dataset is publicly accessible through GBIF portal (http://www.gbif.org/dataset/7db4f705-61ae-4c6e-9de2-06674e7d46b2). Following the latest biogeographic division of the country, ~53% of the species (76 species) inhabit the Iranian Province, ~41% (60 species) the Western Asian mountain transition zone, ~9% (13 species) the Turanian Province, and ~18% (27 species) the Arabian Province. In addition, ~2% (3 species) reach Iran from the Indo-Malay biogeographic region and ~2% (3 species) are believed to have been introduced to Iran by humans. Endemic species (46) represent ~32% of the known species diversity. The most species-rich family of lizards in Iran is Lacertidae with 47 species, followed by Gekkonidae (41), Agamidae (18), Scincidae (15), Phyllodactylidae (10), Sphaerodactylidae (4), Eublepharidae and Uromastycidae (3), Anguidae and Varanidae (2), and Trogonophidae with one representative.

The composition and distribution of the vertebrate fauna of Afghanistan remain poorly documented and in recent decades little new data have become available due to a series of wars and the resulting unstable security conditions. As Afghanistan returns to some semblance of normalcy, baseline faunistic data will be particularly important for establishing national conservation priorities as well as for placing Afghan taxa into their broader phylogenetic and zoogeographic contexts. We here provide an updated checklist of the herpetofauna of Afghanistan based in part upon biodiversity archives of specimen records from several museum and private collec- tions as well as literature references and field research. The herpetofauna of Afghanistan consists of 118 species and subspecies belonging to 58 genera and 21 families. Seven species are endemic to the country, whereas 18 taxa have to be delet- ed from previous lists of the Afghan herpetofauna. Afghanistan’s primary zoogeo- graphic relationship to the Palearctic Region is reaffirmed but with secondary influ- ence from the Oriental Region. Immediately following the checklist, two sections provide information about species probably occurring in Afghanistan and previous- ly mentioned species that are now recognized as absent.
