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

GEOGRAPHICAL DISTRIBUTION OF TABANIDS 195 7-3. Fig.: Occurrence of Philipomyia aprica Meigen, 1820 (sign X) and Philipomyia graeca Fabricius, 1794 (sign O) - along the Drava river in Somogy County Drava River, this species was also recorded in eastern Croatia and in the Mediterranean part of Croatia (MAJER et al. 1995; KRĈMAR, 1999). The second new species is Hybomitra distinguenda collected at the locality in Brodic (XL 79), 18 June 2005 (19 ). This species appears exclusively on the mountain massifs of Eastern Croatia, in habitats overgrown with woods of oak and beech (KRĈMAR & MIKUSKA, 2001). The third new species is Heptatoma pellucens collected on the localities: Legrad (XM 42), 28 July 2005 (19 ), Ferdinandovac (XM 70), 20 August 2005 (19 ). This species inhabits various types of biotopes and never occur in large number. Finally, fourth new species in the Croatian side is Haematopota italica collected on the two localities: Novaki (YL 07), 18 June 2005 (19 ) and Ferdinandovac (XM 70), 20 August 2005 (19 ). Also, Haematopota italica inhabits various types of biotopes especially near water but is never a common species. Upon the basis of the data published in entomological periodicals and on the basis results of this study along Hungarian and Croatian sections of the Drava river 42 species of Tabanids was determined (Table 1). Occurrence of every each species registered along the Drava River was illustrated on the UTM 1-7 maps (Figs). Discussion The review of the references and of the articles published in entomological periodicals and also on the basis of this study 42 species of horse flies were determined for the flooded areas on Hungarian and Croatian sections of river Drava. The collected sample contains four new species for the study area of which Atylotus flavoguttatus is recently been found in Croatia for the first time (MAJER et al. 1995). This species lives in most Mediterranean countries and in Asia from where they fly as far as into Central Europe (CHVÁLA et al. 1972).
