The paper deals with interpretation of the notion "microphylogenesis reconstruction" and conditions ensuring a relative reliability of the latter. A consistent description of the Lacertaagilis area of distribution and itsprobable history as well as comparison of these data with those on phenogeography and microtaxonomy of the species permitted the history of formation of the recent L. agilis area of distribution to be reconstructed. It gave reasons to raise the question on imperfection of the now adopted intraspecies taxonomy ot L. agilis.
