Empidoidea (Diptera): genera and species new to Hungary L. Papp and M. Földvári Empidoidea (Diptera): genera and species new to Hungary — Four genera of the empidoid flies with two species each of Atelestidae, Hybotidae and Dolichopodidae, and seven species of Empididae are recorded as new for the Hungarian fauna. Six species are proposed to be deleted from the Hungarian list in lack of voucher specimens (or as misidentifications). Key words: Atelestidae, Hybotidae, Empididae, Dolichopodidae, faunistic survey, new records, Hungary. INTRODUCTION The aim of the project "Large blank spots in the Diptera fauna of Hungary" is to collect and to publish species representing dipterous families formerly not recorded from Hungary. Furthermore, species representing not recorded genera are also targets of our activity. Four years of the project (OTKA T30242, 1999-2002) is a reasonable period of time, for which a fair support is provided for true faunistical studies. The results will hopefully be included also in the "Checklist of the Diptera of Hungary" . New findings from the preparatory period have already been published (Papp 1999). In 1999, the first year of the project, these collectings resulted in capturing specimens of numerous genera and species new for the fauna of Hungary; a part of them is reported in this paper. The first significant work on the empidoid flies of Hungary is Thalhammer's (1900) faunistic list. Unfortunately, more than two-thirds of the locality data are out of the borders of the modern Hungary. In addition, a majority of the data was his own data and he was far less good at identifying than collecting dipterous specimens (for instance, knowing some about the life-habits of the species of Wiedemannia, we simply cannot imagine an occurrence of W. zetterstedti (Fallén) in any places in Budapest). There was very little done on these families in the following decades to the big fire in the HNHM in 1956, which annihilated also the collections of Empidoidea. In the last years of the sixties, Dr Mihály Wéber began to work on the empidoid families, which resulted in the publication of two volumes in the series Fauna Hungáriáé: the family Empididae (inch Atelestidae and Microphoridae genera) in 1975 and Dolichopodidae in 1989. He published also several scientific papers on them. Very recently, just after the death of our esteemed fellow-dipterist Dr. M. Wéber the collection of Empidoidea, he had possessed, was returned/given to the Diptera collection of the HNHM, through the courtesy of Prof. Dr. József Majer (Pécs University). All
