A look at the Family Lacertidae

Darevskia

Rock Lizards


Introduction

The genus Darevskia is a relatively new one, having been established within the last ten years or so. Most if not all of its species were formerly considered members of the Lacerta genus, and indeed are still by some authorities. I am as yet uncertain as to the characteristics that led to the creation of this genus from the genus Lacerta, but it seems to be based on lizards from Asia Minor and Caucasus and to contain a fair number of parthenogenetic species. There seems to be a dearth of information on the species listed here, whether on the Net or in print: only Rogner mentions some of them. The www.lacerta.de website contains some excellent photographs, but I am not sure that much work has been done with captive Darevskia lizards. Some at least should be adapt well to captivity, as they are often species accustomed to harsh winters and the cooler climates of Europe, and can therefore be kept outdoors for at least some of the year with the attendant benefits of natural sunlight.

Owing to the difficulty of obtaining information, it should be noted that some of the measurements and common names in these notes are "extrapolations", ie intelligent guesswork based on the measurements of the species and/or genus that the individual species was once held to belong to or the Latin name. The common name is not as important as such, but measurements are and therefore I have tried to show an "extrapolated" size by adding a question mark. I am also indebted as usual to the EMBL database for the distribution details of these species.

Fritz Jürgen Obst, Ferdinand Enke Verlag, Stuttgart 1986. A German-language equivalent but with a rather wider definition of Europe which includes the Transcaucasus, and useful details on the distribution of subspecies. Now apparently out of print.

Reptiles and Amphibians of Europe, Walter Hellmich, Blandford Press, London 1962. Taxonomy is rather outdated but useful on details of appearance, habitat and subspecies.

This Finnish site provides a useful cladistic of the relations between the various Darevskia species.
