Abstract
An electrophoretic investigation of 17 gene loci in 11 populations of Meditteraneans lacertids (Podarcis muralis, P. tiliguerta, P. hispanica, P. sicula, "Archaeolacerta" bedriagae) completed with a dendrogram after unweighted pair groups' arithmetic average cluster analysis of NEI genetic identity values, show: - important differences between Podarcis muralis and Podarcis tiliguerta, apparently sufficient to justify the maintenance of this taxon at the specific level; - important differences between animals of Archaeolacerta, Podarcis and Lacerta s. str. (MAYER et TIEDEMANN, 1982) which would allow to raise Archaeolacerta at a generic statute. This study allows equally to establish the diminution of percentage of polymorphic loci for micro-insular P. tiliguerta populations according to the removal from Sardinia and the estimate separation's time. A tentative phylogenetic explanation is done by the authors.
