The unique isolated population of racerunner Eremias arguta transcaucasica in Armenia is under strong human pressure and seeks urgent conservation measures. The population has a limited area (approximately 9 hectares) on the shore of Lake Sevan, in vicinity of a settlement. Հայաստանում բազմագույն մողեսիկի միակ և մեկուսացված պոպուլյացիան գտնվում է մարդածին գործոնի ուժեղ ազդեցության ներքո, և անհրաժեշտ են անհապաղ միջոցառումներ նրա պահպանության համար: Պոպուլյացիան գտնվում է Սևանա լճի ափին, բնակելի տարածքից ոչ շատ հեռու և գրավում է 9 հա տարածք: Единственно известная изолированная популяция разноцветной ящурки в Армении находится под сильным антропогенным прессом и требует срочных мер по ее охране. Популяция занимает ограниченную площадь (около 9 гектаров) на берегу озера Севан недалеко от населенного пункта.

Ilya S. Darevsky co-described 70 taxa (three genera, 46 species, 21 subspecies) in 44 publications belonging to five orders, eight families of amphibians and reptiles during his career in herpetology. Of this number, three taxa are fossil and 57 taxa are currently considered as valid. By the regions where new taxa were discovered Southeast Asia and Western Asia (includes Caucasus and Asia Minor) dominates. The largest number of descriptions was published in the Russian Journal of Herpetology.

The final part of a series of papers on the lizards of the Caucasus, that have been published in previous years. The paper reports on the life habits, capture and keeping in terraria of several lizards of Soviet Transcaucasia. In these respects the agamid Phrynocephalus helioscopus persi- cus and three species of the lacertid genus Eremias occuring in that area (i. e. strauchi, velox, pleskei) are discussed. Finally a !ist of all lizard species and subspecies actually known to occur in this region is given.

Many regions of the former USSR still re- ceive little attention from Western visitors, herpetologists not excluded. For the Cau- casus Mountains this is all the more sur- prising since the area forms a zone where northern and Middle Eastern flora and fauna meet, and which is thus of considera- bly zoogeographical interest. Presently we find three larger states in the Caucasus: Georgia, Azerbaijan and Arme- nia. Turkey borders to the southwest, Iran to the southeast, and in the north it is the Russian federation. Various smaller parts claim independence. The Black Sea forms the natural western boundary, the Caspian Sea the eastern one. Herpetologically the Caucasus is historically well-known because of the work of Darev- sky and collaborators on the rock lizards (at the time still in the large genus Lacerta, now in Darevskia) and the discovery of the first case of parthenogenesis in vertebrates (DAREVSKY, 1967; DAREVSKII, 1978; DAREVSKY & KULIKOVA, 1961). Below we will concentrate on the results of our field trip to Georgia during the last two weeks of June 2003. Predictably, because of our common interest in the group, the lacertids will receive the most attention.

The lacertid genus Eremias Fitzinger in Wiegmann,1834,consists of approximately 36 species of racerunners,distributed throughout the desert and semi-desert regions from northern China,Mongolia,Korea,central and southwest Asia to southeastern Europe.This short review represents the history of taxonomic studies in the genus Eremias,including affirmation of the genus and its species,distribution characteristics,phylogenetic relationships and historical biogeography.Traditional taxonomic methods,as well as new approaches(mtDNA analysis) are discussed.Future potential research projects on Eremias are outlined,such as phylogeny,phylogeography and speciation process.

An overview of the cases of introduction (both accidental and intentional) of amphibians and reptiles in the Caucasus and Crimea is provided. The introduction cases are systemized in accordance with the goals and ways of introduction and with regards to the expected scale of the impact and its nature. No negative consequences of the introduction of amphibian and reptile species in the Crimea and Caucasus are currently observed on any of the known examples. No cases of species naturalization, which the “invasion” term can be applied to, have been revealed. The importance of allochthonous populations as experimental sites to study microevolutionary processes and ecological adaptations of the species in new environmental conditions is discussed.

Elements of the herpetofauna are in the author`s opinion of great importance for the zoogeographical division of the Palaearctic region. It is suggested that this region be divided into the following four subregions: 1/ arctic, 2/ boreal Euro-Siberian, 3/ bo- real Himalayan-Manchurian and 4/ Mediterranean-Central-Asiatic.
