SYSTEMATICS AND GEOGRAPHIC HISTORY OF THE GENUS PYRGUS IN THE PALAEARCTIC REGION (LEPIDOPTERA, HESPERIIDAE) by R. DE JONG Rijksmuseum van Natuurlijke Historie, Leiden Abstract A systematic and Zoogeographie study on the Palaearctic species of the genus Pyrgus, comprising a taxonomie review, a description of the geographic variation and a reconstruction of the geographic history.

Scope The present study is an attempt to reconstruct the geographic and, in a few cases, the evolutionary history of the Palaearctic species of the genus Pyrgus, on the basis of their recent ranges and geographic variation patterns. The author believes that the high morphologic and ecologie diversity of Pyrgtis can be understood as, at least partially, the result of geographic isolation and subsequent differentiation of former geographically connected populations. The history of Pyrgus, reconstructed in this way, clearly shows the enormous impact of the alternation of Glacial and Interglacial Periods during the Pleistocene, on the distribution and differentiation of the members of Pyrgus. Details of the history, how- ever, are often vague. The history of Pyrgus is discussed in relation to the general history of the Palaearctic fauna. This leads towards a Zoogeographie classification of the Pyrgus species into faunal types; a comparison is made with a classification into distributional types. As taxonomie research must provide the basic facts for the reconstruction of the history, only taxonomically well-known groups can be selected for a historic-zoogeo- graphic study. The Palaearctic members of the genus Pyrgus are such a group. This is mainly due to the work of Rambur (1837-1842), who discovered the great importance of the male genitalia for the identification of the species, of Reverdin (from 1910 onwards), of Warren (1926, 1953) and of Evans (1949). Moreover, Alberti, Kauffmann, Opheim, Picard, and others have contributed to our knowledge, in dealing with detail problems. Nevertheless, there still exists much disagreement about the taxonomy of Pyrgus, especially with regard to the delimitation of species and subspecies. Therefore, it was necessary to review the taxonomy of Pyrgus, before a Zoogeographie study of the genus could be made. It must be emphasized, however, that this review is not the aim of the present study, but only a means to permit a reconstruction of the geographic and evolutionary history of this interesting group, which has fascinated the author for many years. l.b. Taxonomie categories The influence of the application of the biological species concept on the number of species within the genus Pyrgus in the Palaearctic becomes apparent, when we compare the 32 species recognized by Warren (1926) on the base of a typological species concept, with the 19 species recognized by Evans (1949) who accepted a
