The paper provides data on the location of the type specimens of Lacerta agilis var. orientalis Kessler, 1878: 7 syntypes were identified in the collection of the Laboratory of Herpetology of the Zoological Institute of the Russian Academy of Sciences (ZISP). The belonging to the type series is clearly indicated by the dates of their collection, localities and collectors. It is shown that according to the “International Commission on Zoological Nomenclature” (4th edition) this published valid name should be considered for L. a. brevicaudata Peters, 1958 and L. a. grusinica Peters, 1960 as the senior subjective synonym, and for L. a. exigua Eichwald, 1831 as the junior subjective synonym. To preserve the stability of the nomenclature, we designate specimen ZISP No. 22902 from Pyatigorsk as the lectotype of Lacerta agilis var. orientalis. From this point on, this trinomen should be regarded as a junior subjective synonym for L. a. exigua, which complies with recommendation ICZN Art. 74A “Agreement with previous restriction. In designating a lectotype, in order to preserve stability of nomenclature an author should act consistently with, and in any event should give great weight to, previously accepted taxonomic restrictions of the application of the name”. A description of the external morphology of the lectotype and its photograph are given.
