Abstract

The Kashgar Racerunner Eremias buechneri Bedriaga, 1907 is a member of the taxonomically most complicated group, i.e. E. multiocellata – E. przewalskii complex, together with about a dozen of other species inhabiting predominantly arid landscapes of Central Asia. Eremias buechneri is one of the poorly studied representatives of this diverse group of species. This species was described in 1907 by Jakob von Bedriaga based on the study of specimens collected in Central Asia by N.M. Przewalsky and M.W. Pewzow. This species is practically not present in the collections of museums around the world and is known from a limited number of specimens. We clarify the composition of the type series used in in the original description of this species in accordance with article 72.4.1 of the International Code of Zoological Nomenclature and we propose to consider as a type series the specimens mentioned by the author in his description of 1907, with catalogue numbers in the collection of the Zoological Museum (since 1931, the Zoological Institute) clarified from the results of the N.M. Przewalsky expedition reported by Bedriaga (1912) and thus to expand the type series to 59 specimens (1 lectotype and 58 paralectotypes). Of these, four paralectotypes are lost (ZISP 7264.9, 7279.6, 7089.4 and 7264.4) and four specimens are in very poor condition, almost destroyed (ZISP 8286.1–4). Thus, the actual number of specimens currently stored at the Zoological Institute is 55. The paratype E. buechneri ZISP 9131 has been genotyped. Molecular genetic identification of specimens in the type series from different parts of the range appears promising as a future avenue of research.
