A survey on the geogtraphical variation of scalation in the Sand lizard was done by means of both univariate (ANOVA) and multivariate (Canonical discriminant Analysis and cluster of the Mahalanobis distances among centroids). Our results show the existence of two clearly separated groups, in concordance with previous authors. Lacerta agilis garzoni is enough differentiated to by considered a valid subspecies. Lacerta agilis argus is a mere synonym of Lacerta agilis agilis. Lacerta agilis chersonensis despite their overall similarity in pattern and coloration to the so-called Balcanic group belongs to the Caucasic one. Data on the currently known habitat and chorology of Lacerta agilis garzoni are given.

After being voted «Reptile of the year 2020» the sand lizard (Lacerta agilis) was featered extensively in the publications and on the websites of the relevant specialist organizations in Germany, Austria, Switzerland and Luxembourg (- not least in this magazine -), and it has repeatedly served as an attractive advertising medium for the protection of our amphibians and reptiles in the daily press. Nevertheless, numerous activities and conferences fell victim to the pandemic last year. And so it seems only logical to give the sand lizard a second chance. For this reason the German Society for Herpetology and Herpetoculture (DGHT), in cooperation with the Austrian Society for Herpetology (ÖGH), the Coordination Center for Amphibian and Reptile Protection in Switzerland (karch), the Natural History Museum Luxembourg (MNHN) and the Nature and Biodiversity Conservation Union Germany (NABU), annouce the sand lizard «Reptile of the Year 2021».

A first complete list of the reptile type specimens preserved in the Museo Nacional de Ciencias Naturales (CSIC) of Ma-drid (updated until 15 July 2012) is provided. The collection houses a total of 319 type specimens representing 24 taxa belonging to 6 families and 12 genera. There are 22 taxa represented by primary types (19 holotypes, 2 neotypes and 1 lectotype) and at least one paratype, and only two taxa are exclusively represented by one secondary type (paratype). The collection is specially rich in Spanish endemisms. Special attention is deserved by the type series of many subspecies of Podarcis lilfordi described by A. Salvador and V. Pérez-Mellado. All type specimens are housed in the Herpetological collection except Blanus mariae and Psammodromus occidentalis type series and Psammodromus hispanicus (neotype) which are preserved in the DNA/Tissues Collection.

The contact zones of the distribution ranges of closely related reptile taxa are the source of valuable data on the microevolutionary processes in populations, the history of regional faunas origin, and the environmental prefer- ences of the studied forms. Our study is focused on the genetic structure of the populations of sand lizard, Lacerta agilis Linnaeus, 1758, at the Crimean peninsula. This lacertid species inhabits the mountain (afforested) and plain (steppe) parts of the Crimea, being abundant or common in many areas. Lacerta agilis is represented in the Crimea by two subspecies: the widely distributed Eastern (L. a. exigua Eichwald, 1831) inhabiting a large part of Northern Eurasia, and the endemic (L. a. tauridica Suchow, 1927) residing in the Crimean mountains. Mitochondrial hap- logroup affiliation corresponding to one of the subspecies (L. a. tauridica, L. a. exigua or L. a. chersonensis) was established for 225 L. agilis individuals from 81 localities in the Crimea and adjacent mainland territories. The nu- cleotide sequences of the complete cytochrome b gene of mitochondrial DNA (1143 bp) were studied in 75 L. agilis individuals from 68 localities. The genetic distance between both subspecies inhabiting the Crimea revealed by used molecular marker comprised 2.8%, which indicates their early divergence approximately at the transition of Early to Middle Pleistocene (ca. 1 Mya). L. a. tauridica is characterized by a comparatively deep genetic structure. Haplotypes occupying isolated positions on the phylogenetic tree of this subspecies were found in the south-west- ern part of the Crimean Mountains, what might be explained by the localization of L. agilis microrefugia in areas least affected by the Late Pleistocene cooling. Genetic structure of L. a. exigua is more homogeneous. Another important result of our study was an identification of zones of haplogroups «exigua» and «tauridica» coexistence localized along the northern and eastern margins of the Crimean Mountains. The portion of the «exigua» hap- logroup in local populations decreases southward and westward. The observed pattern of the spatial distribution of haplogroups seems to be a result of the hybridization zone formation between the sand lizard subspecies during the Holocene expansion of L. a. exigua. Ecological niches modeling for L. agilis subspecies and analysis of morpho- logical variability of the lizards support the hypothesis of L. a. exigua and L. a. tauridica hybridization in the area of contact of their ranges in the eastern part of the Crimean Mountains.

Les Reptiles des Pyrénées traite en détail les 32 espèces protégées présentes sur l’ensemble de la chaîne (France, Espagne et Andorre). Cette faune herpétologique est le résultat d’une entreprise natu­raliste combinant enquête bibliographique et reportage photographique. Elle propose une vaste synthèse de données relatives à plusieurs champs disciplinaires – systématique, ­taxi­nomie, biogéographie, écologie, biologie… – jusque-là dispersées dans plusieurs centaines d’articles et ouvrages. Les variations phénotypiques et les particularités écologiques des serpents, lézards et tortues occupant l’espace pyrénéen y sont illustrées par de très nombreuses photo­graphies exclusivement réalisées in situ, de 2 m à 3 143 m d’altitude. Des cartes de répartition précises (mailles UTM 10 km × 10 km), basées sur des sources scientifiques, complètent et éclairent le propos biogéographique. Les espèces et sous-espèces endémiques ou subendémiques de la chaîne, de même que celles qui y ont un statut particulier (très localisées, vulnérables…), ont fait l’objet d’une attention par­ti­cu­lière et les menaces qui pèsent sur les reptiles des Pyrénées sont largement exposées. Cet ouvrage sera précieux pour les pyrénéistes, naturalistes et gestionnaires d’espaces naturels de la chaîne (parc national, réserves, sites Natura 2000, parcs naturels régionaux…), qui disposeront là d’une mine d’informations sur le sujet.
