Majer, József and Krčmar, Stjepan: Geographical distribution of Tabanids (Diptera: Tabanidae) of the Drava river along the Somogy County (Hungary), the Koprivničko-križevačka and one part Virovitičko-podravska County (Croatia) - Somogy-megye (Magyarország), Kapronca- és részben Verőce-megye (Horvátország) Dráva-menti bögölyeinek földrajzi előfordulása

184 JÓZSEF MAJER and STJEPAN KRĈMAR There are pastures, pet lands, common oak wood, white willow and black poplar forests. The Tabanids were primarily collected by means of an entomological net on the car or by hand in a car and by the Malaise traps. Collected Tabanids were stored in 70% alcohol, and only later dried, and pinned. All the Tabanids collected in Croatia are kept in the insect collections of the Department of Biology in Osijek. Also, specimens collected in Hungary are deposited in the insect collections of Department of General and Applied Ecology, Faculty of Science Pécs University. The sampled specimens were determined according to the key CHVÁLA et al. (1972), MAJER (1987), and OLSUFJEV (1977). The used classification follows Palaearctic Catalogue (CHVÁLA, 1988). 1.

The determined species were classified into genera: Chrysops, Atylotus, Therioplectes, Hybomitra, Tabanus, Heptatoma, Philipomyia and Haematopota. On the Croatian side of the Drava some species proved to new for the regional fauna of the Atylotus fiavoguttatus (Szilády, 1915), Hybomitra distinguenda (Verrall, 1909), Heptatoma pellucens (Fabricius, 1776) and Haematopota italica Meigen, 1804. The species Atylotus fiavoguttatus was represented by 1 specimen within the sample. They were collected in Legrad (XM 42), 28 July 2005 (19 ). Beside the region along
