Abstract. 355 species belonging to 46 beetle families are listed from the Duna-Dráva National Park. Porcinolus murinus (Fabricius, 1794) (Byrrhidae) is reported from Hungary for the first time. With four figures. Introduction Before the political changes happened in Hungary and Croatia in the early 1990s, the Dráva river was a hardly accessible frontier zone between the two countries. This is the main reason why the riverine forests were maintained in an extent unusual in Hungary and why certain stretches of the river were left unregulated. Fortunately, this situation has not altered in the last years, so this region was declared as part of the Duna-Dráva National Park in 1996. Although the Dráva-sík (= Drava Plain) in geographical sense is part of the Alföld (Great Hungarian Plain), a number of plants and animals, which are found mainly in hilly regions, occur in this region. This is due to the comparatively high precipitation, the less extreme maximum and minimum temperatures and the comparatively large extension of forests. A summary of physical features of the area and the history of the research is given by UHERKOVICH (1997). The exploration of the beetle fauna of what is now the Duna-Dráva National Park dates back to 1984 and 1985 when two volumes were published on the flora and fauna of the Barcsi Borókás (= Barcs Juniper Woodland) Landscape Protection Area. Of the families treated in the present paper, 38 species of Coccinellidae and four species of Endomychidae were written up by MERKL (1985). Later, in 1989-1991, a three-year collecting project was carried out in the Béda-Karapancsa Landscape Protection Area, also resulting in a volume. The author listed 118 species belonging to 22 families (MERKI 1992). Further data from the area are found scattered in HORVATOVICH (1976, 1979, 1980, 1981, 1982). The collecting data reported in the above-mentioned papers are not repeated here in detail. As for the Drava region, a considerable list of species was published from Kétújfalu by SÁR (1992), but the area investigated by him is beyond the border of the national park. This paper is devoted to listing 355 species belonging to 46 families found in the territory of the Duna-Dráva National Park. The overwhelming majority of the investigated material was collected in the 1990s by the staff of the Janus Pannonius Museum, Pécs (S. Horvatovich, S. Nógrádi, J. Sár and Á. Uherkovich). Other persons (amateurs and professionals) were also involved in the project and the material collected by them was shared between the Janus Pannonius Museum and the Hungarian Natural History Museum.
