ABSlRACT: The faunistic research of horse flies in Bosnia and Herzegovina during 2003 resulted in the recording of 30 species, of which Atylotus loewianus, TabanUs bijarius, T. paradoxus, T. rupium, Heptatoma pellucens, f{aematopota pandazisi and H. scutellata are new to Bosnia and Herzegovina. The total number of species of the family Tabanidae currently known in Bosnia and Herzegovina increased to 54. ((EY WORDS: Fauna, Tabanidae, Diptera, Bosnia and Herzegovina

INTRODUCTION Finalization of the project "Fauna Europaea" demanded an urgent elaboration of the horse flies fauna (Diptera: Tabanidae) from the new states in the region of the Central and Western Balkans. The first version was based on the literature data from the previous research, as well as on the basis of the horse flies collections of S. Krcmar and 1. Mikuska. These resulted from the research made in the eighties and early nineties (1991) before the disintegration of the former Socialist Federal Republic of Yugoslavia. During the 1990s no further studies of the horse flies fauna were made because of war operations in this region. Also, the collection which was housed in the Earth Museum in Sarajevo was destroyed during the war and, therefore, not studied by us. Altogether 47 horse flies species from the Bosnia and Herzegovina were determined, 34 species based on literary records, and 13 species were preserved in the collections (Krcmar et at. 2002). Furthermore, some species common in the neighbour states, and clearly expected to occur in Bosnia and Herzegovina as well, were still not recorded from this area. All these facts initiated in 2003 an intensive faunistic research of the horse flies in Bosnia and Herzegovina, the results of which are presented here.

MATERIAL AND METHODS The faunistic research of horse flies in Bosnia and Herzegovina was camed out in 2003 from May to the middle of August. Horse flies were collected at 25 sites covering 12 fields on the UTM grid of Bosnia and Herzegovina. Specimens were collected from the cattle, mostly from the cows. Also netting horseflies in the car and on the windows inside the buildings along the roads was common. Samples were stored in 70% alcohol, and only later dried, and pinned. Of the total number of 399 collected specimens, 396 have been identified and classified following the monograph of Chvala et al. (1972), and the Palaearctic Catalogue (Chvala 1988).

RESULTS Altogether 396 specimens were identified, representing 30 species of horse flies classified in 9 genera (Silvius, Chrysops, Atylotus, Therioplectes, Hybomitra, Tabanus, Heptatoma, Haematopota and Philipomyia) of the subfamilies Chrysopsinae and Tabaninae (Table 1). The majority of specimens, 168 (42,42%), belonged to the genus Tabanus Linne, followed by the genus Atylotus Osten-Sacken with 74 specimens (18,68%), Hybomitra Enderlein with 63 specimens (15,90%), Haematopota Meigen with 49 specimens (12,37%), Philipomyia Olsufjev with 33 specimens (8,33%), Silvius Meigen 4 (1,01 %), Chrysops Meigen 3 (0,75%), and finally the genera Therioplectes Zeller and Heptatoma Meigen with only a single (0,25%) collected specimen. Seven species of horse flies were new for the fauna of Bosnia and Herzegovina: Atylotus loewianus, Tabanus bifarius, T paradoxus, T rupium, Heptatoma pellucens, Haematopota pandazisi arid H. scutellata (for details see Table 1).

Subfamily: Tabaninae Atylotus loewianus (Villeneuve, 1920) - 749: Stijena (WK 78) 1O.VII.2003 49; Lovnica (BQ 62) 22.VII.2003 1 9; Stavci (BQ 72) 1.

This species is known in southern Europe (Spain, France, and Italy including Sicily) and North Africa (Morocco). In the East Mediterranean it is known in Lebanon, Cyprus and Turkey, and in the south-east Europe in Bulgaria and Romania. The northern border of its area of distribution lies in Central Europe, in Hungary, Czech Republic, Germany and Belgium (Chvala et a1. 1972; Parvu 1993; Kili~ 1998). Recorded also from Croatia and Montenegro, the bordering states of Bosnia and Herzegovina (Krcmar et al. 1996, 2002). In Croatia it is the most abundant species within the genus Atylotus. For a long period in 2003, from 10 July to 12 August, at 7 sites covering 5 UTM fields.

Rather a common species in the Mediterranean, from Bulgaria and Turkey to Spain, also North Africa (Morocco, Tunisia), eastwards as far as Iran (ChvaIa et a1. 1972; Parvu & Giray 1984). The northern border of its area of distribution lies in Central Europe, in Hungary, Czech Republic, Austria and Germany (Chv:ila et al. 1972). In Bosnia and Herzegovina found at 2 sites only, though the species is very probably much more widely distributed in Herzegovina.

A South European species recorded from Spain, France, Italy, Greece and Albania, distributed north to Switzerland, Germany, Austria, Hungary and south Poland (Chv:ila et al. 1972). This species often flies in late summer very low over the ground in late ev~ning during dusk and early after nightfall, and females attack horses and homed cattle only after sunset (ChvaIa et a1. 1972). In Bosnia and Herzegovina it was collected at 2 sites, near Jablanica and ZavidoviCi; in Jablanica taken in August inside a restaurant on windows, altogether 34 specimens, 109 and 240". In ZavidoviCi only 1 dead female was found in the city, also on a window. There is another large black horse fly without eyes bands collected on 15 June 2003 on the Pepelari mountain (BQ 61); resembling Tabanus paradoxus in the main key characters, but obviously different; furthermore, caught very early, already in June.

A Mediterranean medium-sized blackish species known in Spain, France, Italy, Albania, Greece and Macedonia, eastwards to Turkey, Armenia and Azerbaijan (Chv:ila et a1. 1972; Leclercq 1965). It has been recorded also in the neighbour Croatia and Montenegro (Kremar et a1. 1996; Kremar et a1. 2002). Northern border of its area of distribution lies in Switzerland, Germany, Austria and Slovenia (ChvaIa et al. 1972; Moucha 1959; Kremar & Bogdanovic 2001). Heptatoma pellucens (Fabricius, 1776) - 1 9: Stavci, ZavidoviCi (BQ 72), l.VIII.2003 19, leg: A. Mikuska. A common Palaearctic species which occurrence in Bosnia and Herzegovina has been expected. It has been recorded in Croatia at 19 sites (Krcmar, 1999; Kremar & Mikuska 2001); not yet found in Serbia and Montenegro, but its occurrence there is also very probable. The only female was netted on the back of a cow. Haematopota pandazisi (Krober, 1936) - 1 9: Jablanica (YJ 23) 8.VIII.2oo3 1 9, leg. J. Mikuska.
